SCOPE These specifications define the mi
3、nimum durability requirements of foams and foam tapes made of various materials including polyurethane, polypropylene foam and pressure sensitive adhesive tapes. 2. APPLICATIONS WSS-M99P48-A1 - The materials defined by this specification are for interior, exterior or underhood applications not cover
4、ed by any other specification. The materials are typically but not limited to a flexible polyether polyurethane or polypropylene foam. WSS-M99P48-A2 The materials defined by this specification are for foam laminated or tack sewn in applications in interior applications. The specification includes fo
5、ams laminated or tack sewn in to vinyl, leather or fabric and are typically but not limited to slab stock flexible polyether polyurethane foams. These must contain a flame retardant for the flame lamination process. For Lamination Requirements refer to WSS-M8P18-B1/B4 and WSS-M8P3-E1/E3. WSS-M99P48-
6、A3 The materials defined by this specification are foam tapes for interior, exterior and underhood applications not covered by any other specification (excludes tape performance specifications for emblems, badges and body side moldings). The foam may be from the same source as those in WSS-M98P48-A1
7、 with a pressure sensitive adhesive (PSA) applied to one or both surfaces. The PSA must be tested on the intended substrate. The supplier providing the final product will be listed on the Ford Material Database (FMD) though all sub-suppliers must provide data to the requirements below if requested.
8、2.1 LIMITATIONS WSS-M99D48-A1 Excluded from this specification are headliner (WSS-M15P27-F/latest), instrument panel (WSS-M15P45-B/latest), acoustical and thermal assemblies and energy absorbing (WSS-M99P32-C/latest), seat cushion (WSS-M15P20-B1/B2/latest), headrest and seat armrest foams (WSS-M15P2
9、6-D/latest) or whose performance is specified separately. WSS-M99P48-A2 These foams may not be made of polyurethane polyester foam since they are not durable when exposed to heat and light. WSS-M99P48-A3 These foam tapes do not contain a biocide and shall not be used in applications where odor or mi
10、ldew control is required, for example Climate Control. Excluded from this specification are tape performance for emblems and badges (WSS-M11P65-A/latest and body side moldings (WSS-M11P65-A2/latest) or whose performance is specified separately.
