APPLICATION This specification was released originally for material used for exterior ornamentation applicat

3、ions that are fully painted (i.e.: bodyside moldings, claddings, rocker panels, wheel lips). Any color additives need to be reviewed and approved by the raw material supplier and Ford Materials Engineering. 2.1 LIMITATIONS This thermoplastic polyolefin elastomer material does not contain ultraviolet

4、 (uv) stabilizers, and must be used in painted exterior applications only. 3.
