APPLICATION These specifications were released originally for materials used in an extruded form as welts or moldings with or without core inserts, for trimming and/or sealing interi

4、or automotive body assemblies such as seats, headlinings, and window openings. The ESB-M1G6-A/ B were released for welts with a hollow core, and the ESB-M1G6-A2/ B2 were released for welts with a polyethylene core. 3. REQUIREMENTS Material specification requirements are to be used for initial qualif

5、ication of materials. 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.4 APPEARANCE (FLTM BI 109-01) The color, pattern, and finish shall match the approved Design

6、Center master sample, or shall be as specified on the engineering drawing. Metallic or pearlescent appearances shall be obtained by incorporating metallic or pearlescent particles throughout the basic vinyl formulation.
