SBR (Styrene-Butadiene Rubber)
The most common type of synthetic rubber in use today. SBR comes in a variety of durometers with around 60 shore “A” being used most often on drive rollers, pulley’s, impact bins/pads and skirt boarding. It has very good impact and abrasion resistant characteristics. 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. High resilient, 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.
In addition to chemical resistance and low permeability to gases, Neoprene offers excellent resistance to oils. Constant temperature limit is 200 °F. Neoprene is compatible with many chemicals for corrosion protection.
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° + capability.
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.
