ABSTRACT:
A method of producing a moulded plastic-rubber composite comprising injection or transfer moulding a thermoplastic high pressure polymerized ethylene polymer so that it is brought, in a molten state, into contact with a prevulcanized rubber component containing up to 55 per cent by volume of a rubbery olefin polymer.
The plastic-rubber composite produced by this method may be used in applications in which hitherto rubber-metal composites have been used, for example valve diaphragms, tire valve bodies, shock absorbers, engine mountings, vibration dampers, compression springs, torsion bushes, flexible drive couplings etc., of which the following is a specification.
