TWO-LAYER THERMOPLASTIC ELASTOMER SHEET

摘要

Disclosed is a two-layer thermoplastic elastomer sheet comprising a skin layer [I] and a reverse surface layer [II], each layer being composed of a thermoplastic elastomer containing a polyolefin resin (A) and an .alpha.-olefin copolymer rubber (B), wherein a difference [(I B) - (II B)] between the amount (I B) of the .alpha.-olefin copolymer rubber (B) contained in the thermoplastic elastomer of the skin layer (I) and the amount (II B) of the .alpha.-olefin copolymer rubber (B) contained in the thermoplastic elastomer of the reverse surface layer (II) is in the range of 5 to 85 parts by weight. The two-layer thermoplastic elastomer sheet of the invention is excellent in vacuum forming properties and can provide molded products excellent in the soft touch and having appearance of softness, appearance of flexibility and appearance of warmth. The sheet of the invention can be widely used for interior automotive trim such as an instrument panel.
