Uncured rubber stocks are used for production of various rubber articles.
Uncured rubber stocks are manufactured from the following elastomers: SIR, BR, SBR, NBR, SCR, EPDM.
Depending on the type of rubber the stocks are designed to operate in air, aqueous medium, weak acid and alkaline solutions as well as in contact with oils and fuels.
Uncured rubber stocks are available in rolled sheets (thickness of a sheet is 8,0-12,0 mm) and in calendered cloth (thickness is 0,9-3,0 mm).
Choice of stock grade depends on its application and working conditions.
