Goodwest has been rubber lining tanks for more than 50 years. Rubber linings are a premium form of corrosion protection for some of the most severe chemical and abrasive environments.

Natural and butyl rubber linings withstand a variety of high-concentration acids and are the optimum choice for high heat and abrasive environments. Additionally, the elasticity of a rubber lining easily accommodates thermal expansion and contraction as well as vibration.

The major benefit of a rubber lining is simply its thickness. Linings for rubber lined tanks are usually applied at a thickness of about 1/4". Thinner-film materials may have similar chemical or abrasion resistance, but when they start to degrade the chemical and/or media quickly reaches the steel. When a rubber lining finally begins to degrade only the exposed surface is attacked while the rubber underneath remains as good as new. This fact allows plenty of time for the problems to be fixed prior to substrate failure.

While many rubber linings may look the same, there are a wide variety of polymers and ingredients that allow them to perform well in different environments. For each polymer (natural rubber, chlorobutyl, bromobutyl, neoprene, nitrile, viton, etc.) there are a variety of different blends and hardnesses.

We install linings manufactured by Goodyear Rubber (Goodwest's sister company), Blair Rubber Co., and Polycorp.

Rubber linings are cut to size and applied by hand in sheets. For irregular shapes and optimum adhesion, they are applied in an un-vulcanized state and then usually cured using heat. The heat reacts with the adhesion system to create an extremely aggressive bond to the steel. Rubber lining tanks can also be chemically-cured without the use of heat for patches or when abrasion resistance is not a concern. Pre-cured tank lining sheet rubber is also applied to flat substrates when a heat cure is difficult or cost prohibitive.

In addition to rubber lining tanks, the following types of equipment are often rubber lined: pressure vessels, tanker trailers, rail cars, hoppers, chutes, pipe, impellers, filter plates, and valves.

Details are incredibly important when something as small as a pinhole in a tank lining can cause disaster. Each type of rubber lining has different properties that are critical to understand. Each substrate requires different application techniques.

Goodwest has some of the most skilled and experienced applicators of rubber linings and other specialty materials in the industry. Each type and sub-type of lining material has unique characteristics and requirements for successful mixing and application.

This knowledge comes from Goodwest's decades of experience applying rubber linings to tanks.

Goodwest has an extensive quality control process to verify and re-verify finished products are free of defects. QC procedures employed during the coating application process include temperature & humidity monitoring, thickness testing, holiday testing, and hardness testing.
