APPLICATION WSS-M4D993-B1 This specification was released originally for material used for intake manifolds and GOR/FEM. This material is formulated to have enhanced welding properties. WRS-M4D993-B2
5、/B3 This specification was released originally for materials containing post consumer or post industrial recycled resin content. This material is used for intake manifolds. 2.1 LIMITATIONS This material absorbs and retains moisture. Part design and tolerances must accommodate changes in part dimensi
6、ons and physical properties due to moisture absorption or loss in the service/assembly environment. This material does not contain UV stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss. This material is not suitable for direct long term exposure to engine coolan
7、t, or direct exposure to strong acids or bases. It is not sutable for use above 150 C. 3. REQUIREMENTS 3.1 APPROVED SOURCES 3.1.1 This specification requires the use of approved sources.
