Abstract

1431370 Laminates BURMAH OIL TRADING Ltd 4 April 1973 [6 Jan 1972] 661/72 Heading B5N [Also in Division C3] Laminates suitable for use as sound proofing materials in automobiles comprise (A) a vacuum formable elastomeric sheet comprising (1) an elastomeric copolymer or terpolymer of ethylene with at least one higher α-olefin and (2) 700 to 2000 parts by weight per 100 parts of elastomer of a filler of specific gravity at least 2 bonded to (B) a spacer or backing material. The elastomeric sheets may be bonded by adhesives to polymeric foams, e.g. polyurethane foams, felt or other non-woven fabrics, or mineral fibres. The elastomer may be a copolymer of ethylene with at least one C 3-10 α-olefin and optionally a conjugated or non-conjugated diene, and may be blended with polypropylene, high density polyethylene, chlorosulphonated polyethylene or extender oil. The filler may be barium sulphate chalk or slate dust.
