"BSB” fenders manufacture from different type of rubber compound according to the requirements of site conditions. Base of these compounds are different such as natural rubber and synthetic rubbers like SBR, EPDM or blend of them .Final compound have excellent U.V resistance, ozone resistance aging, abrasion resistance, resistance of seawater and extreme climate conditions, etc. and final production have specification according to customer request and international standard.
