Rubber 101: Types of Rubber
Endurawear® is Sioux Rubber & Urethane’s proprietary rubber that is specifically engineered to enhance the performance of your machinery, increase equipment life, and keep maintenance costs down. Industrial rubber products play a significant role in various industries, offering a wide range of solutions. Endurawear® is designed to provide excellent impact and abrasion resistance for plates, pulleys, and liners.
SBR (Styrene-Butadiene Rubber)
SBR is the most common type of synthetic rubber in use today. SBR is a versatile rubber that can be used in various forms and is most suitable for sheets, gaskets, and rubber seals. SBR with special additives has moderate resistance to ozone, UV rays, and weathering. SBR rubber has incredible tensile strength, withstanding stretching force without deforming, splitting, or breaking. SBR rubber comes in a variety of durometers with around 60 shore “A” being used most often on drive rollers, pulleys, impact bins/pads, and skirt boarding. One of the most notable advantages of SBR is it has very good impact and abrasion-resistant characteristics. This property makes SBR rubber a preferred choice for applications where materials need to withstand wear and tear caused by friction, abrasion, or surface contact. A good example is about 50% of all car tires are made from various types of SBR’s.
Natural rubber is relatively low-cost lining material for both corrosion and abrasion protection. This type of rubber is a versatile and elastic material made from the latex sap of rubber trees. Its exceptional elasticity and resilience make it valuable in various industrial applications. This type of rubber is used in items like conveyor belts, seals, and industrial hoses because it can endure stretching and compression without losing its original shape. Moreover, its natural origin and biodegradability make it a sustainable choice. High resilience, 40-50 durometer, the soft natural rubber exhibits superior abrasion resistant qualities compared to other lining materials. Soft natural rubber offers excellent protection from many corrosive materials. Material is available in red or black if color contamination is a consideration. Typical applications include pump housing, fan systems, lining, and parts tumbling barrels. Constant to intermittent temperature limits are 150 ° to 180 °F.
Neoprene is a synthetic rubber polymer, commonly employed for corrosion protection in various industrial applications. This commercial and machine rubber option is waterproof and provides an effective barrier against moisture. Neoprene offers moderate resistance to UV radiation, making it a suitable choice for outdoor applications where prolonged exposure to sunlight may occur. This type of rubber is a versatile and reliable material, offering durability, flexibility, and other valuable properties. In addition to chemical resistance and low permeability to gases, Neoprene offers excellent resistance to oils. It is employed in a wide range of industries and applications where safeguarding against corrosion is essential for equipment longevity and safety. Constant temperature limit is 200°F. Neoprene is compatible with many chemicals for corrosion protection.
Chlorobutyl rubber is a synthetic rubber compound, a great machine and commercial rubber product. Chlorobutyl rubber linings provide reliable protection against both chemical corrosion and abrasion, helping extend the lifespan of equipment, maintain product quality, and ensure safety in various industrial processes and environments. This lining offers excellent resistant to a wide range of corrosive environments over other elastomers. It is also available in a high-temperature compound with 300°F + capability.This type of rubber is used in tire liners and seals for machines that work with chemicals.

word for it:
It is hard to beat from the aspect of economy, abrasion resistance, lining integrity, and high temperature resistance. [Sioux Rubber] has done an excellent job of installing and testing rubber liners that we have used in our scrubbers and reactors… delivery times are accurate… and the quality of the job is top notch.

What is durometer?
Durometer is one of several measures of the hardness of a material. Hardness may be defined as a material’s resistance to permanent indentation. The durometer scale was defined by Albert F. Shore, who developed a measurement device to measure Shore hardness in the 1920s. The term durometer is often used to refer to the measurement as well as the instrument itself. Durometer is typically used as a measure of hardness in polymers, elastomers, and rubbers.
