Abstract

The basic material, e.g. polyolefins, with an evenly dispersed cross-linking agent is extruded under pressure and temps. below reaction levels, into a reaction chamber where the cross-linking action is effected under controlled temp. and press. using heaters and a piston. The cross-linked material is then passed to an injector for moulding. A flexible system for processing material into cross-linked high polymers without complex sealed pressure reaction units.
