SCOPE The material defined by this specific
3、ation is a laminate consisting of a solid vinyl film, an expanded vinyl layer and a texturized polyester fabric. 2. APPLICATION WSS-M2F156-C was developed for Global commercial vehicles and truck seating applications that require high wear and flexibility resistance. WSS-M2F156-C4 was released origi
4、nally for material used in interior trim as perforated covering for seat applications in commercial vehicles and trucks. Any other applications must be evaluated by the appropriate product engineer with functional testing and approved by Materials Engineering. 3. REQUIREMENTS In addition to the requ
5、irements listed herein, this material shall meet all requirements of the WSS M8P3-E1/E3 or latest Performance, Flexible Polymeric Film, Interior Quality specification. Laminated materials must meet the lamination requirement per WSS-M8P3-E3 or latest performance specification. 3.1 APPROVED SOURCES T
