Harris, NA Controlled document at www.MATS Copyright 2016, Ford Global Technologies, LLC Page 1 of 7 POLYETHERIMIDE (PEI) MOLDING COMPOUND, WSS-M4D716-B1 1. SCOPE The material defined by this specification is a
2、long term high heat resistant thermoplastic injection molding compound based on polyetherimide (PEI). This material exhibits high dimensional stability and excellent electrical properties. This material is self-extinguishing (SE) without flame retardant additives. 2. APPLICATION This specification w
3、as released originally for material used for the fuse box and headlamp reflectors. 2.1 LIMITATIONS This material does not contain UV stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss. No metallized regrind is allowed. 3. REQUIREMENTS 3.1 APPROVED SOURCES This s
4、pecification is part of the Ford Co-Managed Buy (CMB) agreement. Tier 1 Molders who are participating under the CMB agreement must use one the following approved sources (deviations require approval from Raw Materials Purchasing and Materials Engineering): The approved source for this specification
5、is Sabic Ultem AUT200. Molders not on the CMB program or regions without CMB are required to use materials listed on the Ford Approved Source List (ASL), and are encouraged to use the CMB sources listed above.

6、n is listed on the drawing, CAD file, or other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer 3.2 CONDITIONING AND TEST CONDITIONS All test values are based on material conditioned for not less than 24 h prior to testing i
7、n a controlled environment of 23 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material should occur in the conditioning environment or soon after removal. 3.3 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms from initial material approval shall constitute the
8、reference standard and shall be kept on file at the designated material laboratory. The material supplier shall ensure that all future material supplied to the specification shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions.
