SCOPE The material defined by this specification is a GEMSTONE pattern, needled non-woven polyester fabric with acrylic binder and it is two-tone printed. 2. APPLICATION This specificatio
3、n was released originally for material used as a cover material for headliners. Limitations This cover material must always be bonded 100 % to a substrate material to form a composite (localized or spotty adhesion is unacceptable) in order to meet flammability requirements. Any other application mus
