⚠️ CRITICAL INDIANA FILING DEADLINE WARNING

Indiana’s statute of limitations for asbestos-related disease claims is TWO YEARS from the date of diagnosis — not from the date of exposure.

Under Ind. Code § 34-20-3-1, if you or a family member has been diagnosed with mesothelioma, asbestosis, or another asbestos-related disease linked to work at the Uniroyal Mishawaka Rubber Plant, you may have as little as two years from that diagnosis date to file a civil lawsuit in Indiana courts. Once that deadline passes, it cannot be extended — your right to compensation may be permanently lost.

Asbestos bankruptcy trust fund claims may be filed simultaneously with your civil lawsuit under Indiana law, and most trusts have no strict statutory filing deadline — but trust fund assets are finite and depleting as claims mount. Every month you delay is a month closer to reduced recoveries.

Do not wait. If you have been diagnosed, contact an asbestos attorney in Indiana today.

Asbestos Exposure at Uniroyal Mishawaka Rubber Plant: What Former Workers Need to Know

A mesothelioma diagnosis changes everything — and if that diagnosis is connected to work at the Uniroyal Mishawaka Rubber Plant, you need to understand exactly what your legal options are and how quickly they can disappear.

For decades, the Uniroyal Mishawaka Rubber Plant employed thousands of workers from St. Joseph County in rubber manufacturing operations. Many of those workers — and their families — are now facing mesothelioma, asbestosis, and other life-threatening diseases linked to asbestos exposure in Indiana’s industrial sector.

If you or a family member worked at the Uniroyal Mishawaka plant and has been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related disease, you have legal rights under Indiana law. You may be entitled to compensation through personal injury lawsuits filed in Indiana courts, asbestos trust fund claims, or settlements. Under Ind. Code § 34-20-3-1, Indiana’s two-year statute of limitations begins running on the date of your diagnosis — not your last day of work. This page explains what happened at the Mishawaka facility, who may have been exposed to asbestos-containing materials, what diseases result from that exposure, and what steps to take next under Indiana’s legal framework for asbestos litigation.

Understanding Your Rights: Indiana Asbestos Lawsuit Filing Deadline

The Two-Year Clock Starts at Diagnosis

Indiana law provides a two-year statute of limitations for filing asbestos-related disease lawsuits. Courts have interpreted this provision in ways that catch workers and families off guard:

The clock starts on your diagnosis date — not your last exposure
The clock starts on your diagnosis date — not when symptoms first appeared
If you delay seeking medical confirmation of your condition, you may unknowingly trigger this deadline before you ever speak to an attorney

Example: If you were diagnosed with mesothelioma on January 15, 2025, you have until January 15, 2027 to file your lawsuit. After that date, Indiana courts will dismiss your claim as time-barred — regardless of how clear your exposure history may be.

Why This Deadline Matters for Gary, Lake County, and St. Joseph County Workers

Workers at northern Indiana industrial facilities — including the Uniroyal Mishawaka plant in St. Joseph County, U.S. Steel Gary Works, and Bethlehem Steel Burns Harbor in Lake County — often worked with asbestos-containing materials for decades before receiving any diagnosis. The latency period between initial exposure and mesothelioma diagnosis can span 20 to 50 years. Workers who spent their careers in northern Indiana’s industrial corridor may not realize they have a diagnosable asbestos-related condition until years after the exposure that caused it — and by then, the two-year clock is already running.

Asbestos Trust Fund Claims Have No Statutory Deadline — But Assets Are Depleting

Indiana law and federal trust fund rules allow you to file bankruptcy trust fund claims simultaneously with your civil lawsuit, and most asbestos trust funds have no strict statutory filing deadline. However:

Trust fund assets are finite — they do not replenish as new claims are filed
As more claims are filed nationwide, individual recovery percentages decline
Delaying a trust fund claim means accepting a smaller recovery share when your claim is eventually filed

The strategy under Indiana law is to act on both fronts simultaneously: file your civil lawsuit before the two-year deadline expires, and file trust fund claims before assets are further depleted.

What Was the Uniroyal Mishawaka Rubber Plant?

From U.S. Rubber to Uniroyal — A St. Joseph County Industrial Institution

The Mishawaka rubber plant traces its origins to the late 19th and early 20th centuries, when Mishawaka emerged as a national center for rubber goods manufacturing. The facility operated under several corporate identities over its long industrial history — including the United States Rubber Company — before becoming part of the Uniroyal brand, one of the most recognized names in American industrial rubber production.

At its peak, the facility:

Employed thousands of workers from St. Joseph County and surrounding northern Indiana communities
Produced industrial belting, footwear, and specialty rubber compounds
Operated as a cornerstone of Mishawaka’s manufacturing economy for much of the 20th century
Ran continuously through the era when asbestos-containing materials were most heavily used in American industry

Many workers spent entire careers at this plant, working alongside fathers, brothers, and neighbors in a close-knit northern Indiana manufacturing community. The facility’s decades-long operational history — particularly during the mid-20th century — coincides precisely with the period when asbestos-containing materials were standard throughout American industrial facilities.

The Asbestos Era in Indiana’s Industrial Corridor

The Uniroyal Mishawaka plant operated contemporaneously with other major asbestos-impacted Indiana facilities including U.S. Steel Gary Works, Bethlehem Steel Burns Harbor, Inland Steel East Chicago, and Cummins Engine Columbus. Workers who spent careers in northern Indiana’s industrial corridor — moving between facilities or working for contractors who also served those sites — may have faced cumulative asbestos exposures across multiple locations.

Former Uniroyal Mishawaka workers may have also worked at:

Other rubber manufacturing facilities in Indiana
Steel mills in Lake County (Gary, Burns Harbor, East Chicago)
Power generation and boiler facilities
Automotive and machinery manufacturing plants

If you worked at multiple Indiana industrial facilities, your asbestos exposure history may be more complex than a single-site case. An experienced Indiana asbestos attorney can help identify every potential exposure source and every liable party — not just Uniroyal.

Why Asbestos Was Used in Rubber Manufacturing Facilities

Heat-Intensive Production Created Demand for Asbestos-Containing Materials at Every Stage

Rubber manufacturing runs on sustained, extreme heat — and that created substantial demand for thermal insulation throughout every rubber plant in America during the 20th century.

Core manufacturing processes that generated intense heat:

Rubber mixing — Large internal mixing machines (Banbury mixers) required precise high-heat environments to process raw rubber compounds
Calendering — Rubber compounds ran through heated steel rollers at extreme temperatures to produce sheets of uniform thickness
Vulcanization — Steam-driven equipment operating above 300°F cured and hardened rubber products

All of this equipment required insulation. For most of the 20th century, asbestos-containing materials were the insulation of choice for industrial steam systems and high-heat manufacturing equipment. Manufacturers selected these products because they were inexpensive, highly effective as thermal insulators, readily available from major national suppliers, and easy to install and maintain.

What the workers installing and maintaining those materials were never told: the manufacturers who supplied them had known for decades that asbestos caused fatal disease. Cost savings and production speed took priority over worker safety.

Extensive Steam Infrastructure Created Multiple Exposure Points Throughout the Facility

Beyond the process equipment itself, a large rubber plant like the Uniroyal Mishawaka facility required extensive steam delivery systems throughout the building:

Steam supply and return lines
Flanges, valves, and boilers
Pipe fittings and connections
Boiler rooms and equipment vaults

Every linear foot of those systems was a location where asbestos-containing pipe insulation, block insulation, fitting covers, and gaskets may have been applied — and periodically torn out during maintenance and repair. Workers performing routine maintenance, emergency repairs, or equipment modifications may have been exposed to asbestos fibers released during these tasks.

Asbestos-Containing Materials Allegedly Present at Uniroyal Mishawaka: Products and Manufacturers

Based on industrial operations conducted at rubber manufacturing plants of this era and documented exposures at comparable Indiana facilities — including U.S. Steel Gary Works, Inland Steel East Chicago, and Bethlehem Steel Burns Harbor — workers at the Uniroyal Mishawaka Rubber Plant may have been exposed to asbestos-containing materials supplied by several major manufacturers.

Pipe Insulation and Block Insulation — Johns-Manville and Owens-Illinois

Johns-Manville Corporation — the nation’s largest manufacturer of asbestos-containing insulation products for most of the 20th century — is alleged to have supplied pipe insulation, block insulation, and sectional pipe covering to rubber manufacturing facilities throughout Indiana. Workers at the Mishawaka plant may have been exposed to Johns-Manville asbestos-containing materials on steam lines, boiler systems, and process equipment.

Johns-Manville’s distribution network extended throughout Indiana, and the company’s products are alleged to have been present at major Indiana industrial facilities of this era including U.S. Steel Gary Works and Inland Steel East Chicago. The same distribution channels that supplied the Gary steel corridor also served northern Indiana manufacturing facilities.

Owens-Illinois (later part of Owens Corning) manufactured asbestos-containing insulation products including “Kaylo” pipe insulation, which reportedly contained chrysotile asbestos. Kaylo was widely distributed to industrial facilities throughout Indiana during the mid-20th century — including facilities in Lake County, Porter County, and St. Joseph County — and may reportedly have been present at the Uniroyal Mishawaka plant.

Flooring, Ceiling Tile, and Insulation — Armstrong World Industries

Armstrong World Industries manufactured floor tile, ceiling tile, and insulation products that reportedly contained asbestos. Armstrong products were common in Indiana industrial facilities throughout the mid-20th century. Workers at the Mishawaka plant may have encountered Armstrong asbestos-containing materials in shop floor tile, ceiling tile in administrative and shop areas, and insulation wrapping on process equipment.

Insulating Cement and Finishing Products

High-temperature insulating cements and finishing compounds — many of which reportedly contained asbestos — are alleged to have been used to insulate irregular surfaces such as elbows, tees, and valve bodies throughout the plant. Products from the following manufacturers are alleged to have released asbestos fiber during mixing, application, and removal:

Combustion Engineering — high-temperature insulating materials for boiler and steam system applications
Eagle-Picher — specialty refractory and insulation products
W.R. Grace — asbestos-containing insulating compounds and coatings

Gaskets, Packing Materials, and Valve Seals — Garlock and Crane Co.

Steam systems required regular maintenance of flanges, valves, and pumps. Gasket materials and valve packing used throughout the plant during the mid-20th century reportedly contained asbestos.

Manufacturers allegedly supplying these materials:

Garlock Sealing Technologies — asbestos-containing gasket and packing materials for steam systems
Crane Co. — valve packing and seal materials reportedly containing asbestos

Workers who routinely cut, installed, or removed these materials may have been exposed to asbestos-containing products during each maintenance or repair task. The same Garlock and Crane products documented in asbestos litigation involving U.S. Steel Gary Works and Cummins Engine Columbus are alleged to have been supplied to rubber manufacturing facilities throughout Indiana during this era.

Boiler Refractory and Insulation Linings

Boilers at the facility required refractory linings and related insulation products, many of which reportedly contained asbestos during the mid-20th century. Manufacturers commonly cited in Indiana asbestos litigation for products of this type include:

Combustion Engineering — refractory bricks and insulation linings reportedly containing asbestos
Eagle-Picher — high-temperature refractory products
