LINING SHEET FOR CEILING OF VEHICLE AND LAMINATED BODY HAVING LINING SHEET

摘要

PURPOSE: To obtain a thin lining sheet with uniform thickness for the ceiling of a vehicle by providing a partially bridged thermoplastic elastomer obtained by dynamically heat-treating a mixture composed of specified poly-1-butene resin, olefinic thermoplastic elastomer and so on in the presence of organic peroxide. CONSTITUTION: A lining sheet for the ceiling of a vehicle is formed by [I] 5-40wt. parts poly-1-butene, [II] 50-80wt. parts olefine thermoplastic elastomer, and [III] 5-30wt. parts polypropyrene resin (the total weight of components [I], [II], and [III] is 100wt. parts). The olefine thermoplastic elastomer [II] comprises 30 90wt parts ethyleneα-olefine copolymer rubber (a) and 10-70wt. parts polypropyrene resin (b) (the total weight of components (a) and (b) is 100wt. parts). The sheet is a partially bridged thermoplastic elastomer obtained by dynamically heat-treating the above mixture in the presence of organic peroxide.
