It’s hardly surprising the Hoja de caucho SBR (red rubber) is one of the most widely used gasket materials. Firm and smooth, it conforms readily to mating surfaces. Good tensile strength and abrasion resistance ensure durability, providing it’s not used in the wrong places. Here’s what you should know about using red rubber gasket material.
SBR is a copolymer of styrene and butadiene and has properties similar to Natural Rubber. It has good abrasion resistance, excellent impact strength, very good resilience and a high tensile strength. The temperature range of SBR is -40˚F to 180˚F. SBR can be compounded for use as lining rubber, conveyor belt covers and other extremely demanding applications.
