Rubber Sheets
Information
Rubber has good resistance to mild acids and alkalis, salts, and chlorine solutions. It has poor resistance to oils and solvents and is not recommended for use with ozone. Its temperature range is very limited.
Rubber with textile inserts suitable for current applications, without specific heat-resistance characteristics. Good resistance to ozone and atmospheric agents. It is usually cut and used for industrial lining. It is the most popularly used rubber on the market.
