METHOD FOR MAKING ARTICLES BY RADIO FREQUENCY WELDING

摘要

Surfaces of a blend of (1) unvulcanized chlorosulphonated polyethylene and/or chlorinated polyethylene, (2) a bituminous petroleum derivative of softening point in excess of 100 DEG C. and an asphaltene content in excess of 25% by weight and (3) a noninterfering anti-blocking agent are joined by radio frequency dielectric welding.
