2、ologies, LLC Page 1 of 8 THERMOPLASTIC POLYOLEFIN ELASTOMER (TPO), WSS-M4D550-A11 18% TALC FILLED HIGH IMPACT, MOLDED IN COLOR, INTERIOR 1. SCOPE The material defined by this specification is a low gloss, high impact, rigid thermoplastic polyolefin elastomer (TPO) injection molding compound, mineral

3、 (talc) filled, UV stabilized, high scratch resistant for interior applications that require low temperature ductility. 2. APPLICATION This specification was released originally for material used for the 2008 Focus instrument panel with a seamless deployable passenger airbag. 2.1 LIMITATIONS Seamles

4、s airbag applications do not allow the use of regrind. This material is not to be used in applications requiring painting because it contains an anti-scratch additive. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Company

5、s 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 minimum, maximum or range was establis

6、hed 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 recycled materials as defined by WRS-M99P42-

7、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 meet the requirements outlined in WSS

8、-M99P2222-D1/Latest, Performance, Vehicle Interior Environment Quality Material/Component Requirements. Data must be included in material submission package. 3.1.5 Performance Criteria: Parts using this specification shall meet the appropriate performance specification, WSS-M15P4-F/Latest for Hard,

Conduct a tactile eva

13、luation 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 deterioration. Use regional choice colors for

14、 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 Rating 2 at 2N, max These values are de
