Abrasion Resistant and Protection from chemicals and solid
Abrasion Resistant Polyurethane Linings
Polyurethane liners, urethane coatings and urethane customized molds are produced from proprietary formulations and processing techniques. Urethane liners are often used when wear issues need to be solved and often save equipment from costly downtime and maintenance. The many outstanding physical properties of urethane along with its varied applications make it a material of choice.
Types Of Polyurethane Liners
ISM manufactures drop-in, bolt-in, magnetic, sheet and bonded cast polyurethane liners. Urethane can be bonded to a variety of materials to enhance the lifespan of manufactured parts and equipment.
Liners are often used for:
- Metal hoppers
- Chutes
- Grain bowls
- Discharges
- Bins
- Pipes and Fittings
- Trailers
- Road maintenance equipment
Cast lined are bonded for ultimate adhesion and protection. Bolt-in liners are perfect for protecting both small and large applications. This application allows for certain segments of the liner to be removed based upon wear allowing you to replace only sections that are needed. Magnetic Liners can be easily placed to aid in a variety of wear patterns. Large magnets hold panels in place giving your application a lot of flexibility. Sheet liners are a great option for customers looking to create a liner on-site to specific dimensions and needs. We can also create sheets in specific shapes too.

Abrasion Resistant Linings
Customized Cast Urethane
Our in-house machine shop allows us to easily manufacture a cast mold to meet your specific liner needs. Cast urethane is economical as there is little to no tooling costs. Our facility can handle both small and large production runs to meet your needs. Plus, we can handle the stripping of old polyurethane liners which will save your operation time and money. After the stripping process, our machinists are able to repair parts and materials needing a bonded urethane liner.
What's The Difference Between A Cast Urethane Liner And A Spray-In Liner
At ISM, all of our liners are cast urethane liners. We do not manufacture urethane spray-in liners. Many people think cast urethane liners and spray-in liners have comparable characteristics and durability. However, this is simply not the case. Cast urethane liners are much thicker than spray-in liners, often ranging in thickness from ¼” to 1”. All of our cast urethane is custom-made to fit our client’s application and design needs. Plus, cast urethane is cured in a high-temperature oven ensuring its high performance and amazing durability. Simply put, cast urethane liners far exceed the wear life of spray-in liners.
Advantages of Polyurethane Compared to Other Materials
Polyurethane Material Advantages
| vs Plastic | vs Rubber | vs Metal |
