2、AMLESS INSTRUMENT PANEL 1. SCOPE The material defined by this specification is a dry blended, slush molded polyvinyl chloride or polyvinyl chloride alloy skin that is UV stabilized, heat stabilized, and has excellent low temperature ductility used for soft doors or seamless instrument panels. 2. APP

3、LICATION This specification was released originally to be used as a flexible molded skin for the seamless instrument panel over foam and plastic substrate for the 2010 Fusion/Milan/MKZ. 2.1 LIMITATIONS If the plastic substrate is an olefin based material, the substrate must be pretreated with either

4、 adhesion promoter, flame, or plasma treatment and no slip agent should be present unless validated with the slip agent. If the plastic substrate is a styrenic based material, the PVC should not come in direct contact with the substrate or chemical compatibility testing must be performed. No topcoat

5、 is required, but may be painted for two-tone applications and must be tested to WSS-M2P188-A1. 3. REQUIREMENTS This material must also meet the requirements in WSS-M15P45-B and also WSS-M2P188-A1 if painted. The final assembly must meet the IP and PAB SDS requirements for each new vehicle program.
