ABSTRACT:
A method of producing a molded plastic-rubber composite comprising injection or transfer molding a substantially linear crystalline low pressure solution olefin polymer so that it is brought, in a molten state, into contact with a prevulcanized rubber component containing up to 70 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.
