SCOPE The material defined by this specification is a low gloss, medium impact, rigid thermoplastic polyolefin ela

3、stomer (TPO) injection molding compound, mineral (talc) filled, UV stabilized and high scratch resistant for interior use. 2. APPLICATION This specification was released originally for material used for an unpainted instrument panel with a non-seamless passenger airbag. 2.1 LIMITATIONS This material

4、 should not be used as an instrument panel substrate with a seamless passenger airbag. This material is not to be used in applications requiring painting because it contains internal anti-scratch additive. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part

5、 producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1.1 Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s), which indicated that the mean and +/- 3 sigma values were to be reported. The specification

6、minimum, maximum or range was established using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test to meet specification limits. 3.1.2 This specification is based on virgin materials. Materials with post-consumer, post industrial, or repolymerised recycl

7、ed materials as defined by WRS-M99P42-A1 are preferred and should be used whenever feasible. 3.1.3 The use of regrind is permitted, for economic / environmental reasons, with compliance as indicated in Ford Engineering CAD and Drafting Standard E-4. 3.1.4 Materials used in interior applications must

8、 meet the requirements outlined in WSS-M99P2222-C1/Latest, Performance, Vehicle Interior Environment Quality Material/Component Requirements. Data must be included in material submission package.

13、ol for one hour. Conduct a tactile evaluation and report any tackiness. Visually evaluate and report any spewing or other exudation. After exposure the material shall show no fading or color change in excess of specified AATCC rating. In addition, there shall be no cracking, crazing or other deterio

14、ration. Use regional choice colors for initial approval and report color house used. See Table 2 for additional color durability submission requirements. 3.3.2 Resistance to Scratch and Mar (FLTM BO 162-01, Specimen I) Scratch Rating 2 at 2N, max Whitening/Color Change Rating 1 at 15N, max Marring R
