Wilson, NA Controlled document at www.MATS Copyright 2018, Ford Global Technologies, LLC Page 1 of 10 POLYCARBONATE (PC), OPTICAL GRADE, HIGH MELT FLOW, EXTERIOR WSS-M4D1052-B1 POLYCARBONATE (PC), OPTICAL GRADE,
2、LOW MELT FLOW, EXTERIOR WSS-M4D1052-B2 POLYCARBONATE (PC), OPTICAL GRADE, LOW MELT FLOW, INTERIOR WSS-M4D1052-B3 1. SCOPE The material defined by this specification is a thermoplastic injected molded compound based on polycarbonate. These are non UV-stable materials. 2. APPLICATION WSS-M4D1052-B1 th
3、erefore it requires a UV stable coating for exterior applications. Long term exposure to direct sunlight will cause yellowing. This material should be evaluated for potential incompatibility with other materials that they may come in contact with. Refer to the appropriate performance specification.
4、HALS (Hindered Amine Light Stabilizers) IS PROHIBITED IN PC AND PC/ABS RESINS. HALS UV stabilizer degrades the polymer in the presence of moisture causing cracking/crazing of the resin. WSS-M4D1052-B1 only: These materials should not be considered for parts with snap-in features or features that are
5、 notch-sensitive, as they tend to break in these types of applications. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification 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 req
6、uire approval from Raw Materials Purchasing and Materials Engineering). 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. Only the sources identified on the Approved Source Lis
7、t can be used when this specification 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.

8、ogies, LLC Page 2 of 10 Approval of new sources requires the completion of the latest version of the FMD template. Data should be submitted at the time as the specification data package. Only one FMD package is required per trade name approved, FMD is not required for each manufacturing site. FMD is
9、 required for new site approvals that do not have an existing FMD record. 3.2 CONDITIONING AND TEST CONDITIONS All test values are based on material conditioned for not less than 24 h prior to testing in a controlled environment of 23 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material
10、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 reference standard and shall be kept on file at the designated material laboratory. The material s
11、upplier 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. 3.4 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS 3.4.1 Many 4D resin specifications prior to 2011, i
12、dentified 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 established using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test. 3.4.2 This
13、 specification is based on virgin material and does not allow the addition of recycled content (PIR/PCR). 3.4.3 The use of regrind is permitted, for economic / environmental reasons. Part manufacturers using this specification must complete DV and PV testing with the maximum allowable amount of regr
14、ind and the maximum allowable regrind content must be specified on the engineering drawing. Any changes to what is specified on the drawing (no specific amount implies zero regrind) must be approved by Materials and PD Engineering through the formal Ford Motor Company process (SREA) or Engineering N
15、otice. 3.4.4 Performance Criteria: WSS-M4D1052-B1 split screen at 2000 cm-1, Strongest absorption band in the spectrum should bottom out in the 10 to 20 % transmittance range. Supplied spectrum should span a standard sheet of copy paper, preferably in landscape mode, with the x-axis delineated well
16、so that the location of the absorption bands in cm-1 can be determined. TGA (% by weight, Room temperature to 900 C in nitrogen at 15 C /minute, cool to 600 C then 900 C in air at 15 C /minute, on plot, report Weight % loss in Nitrogen, Weight % loss in Air, and % Ash) Specific Heat Capacity, Cp (J/

GENERAL INFORMATION The information given below is prov
19、ided for clarification and assistance in meeting the requirements of this specification. Contact for questions concerning Engineering Material Specifications 4.1 APPROVAL OF MATERIALS Suppliers desiring approval of their materials shall first obtain an expression of interest from Purchasing, Design
20、 or Product Development, and Materials Engineering. The supplier shall submit a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of the Material Specification. Tested mat
21、erial samples must be available for review upon request and kept for a minimum of one year. Upon request, the supplier will review the associated quality control documents (Process Failure Mode and Effects Analysis, Control Plans, Certification testing) with Ford. 4.2 SUPPLIERS ONGOING RESPONSIBILIT
22、Y All materials must be equivalent in all characteristics to the material upon which approval was originally granted. Prior to making any changes to the material originally approved, whether or not such changes affect the materials ability to meet the specification requirements, the supplier shall n
23、otify the affected Supplier Technical Assistance (STA), Purchasing, and Materials Engineering activities of the proposed changes (with reasons) by submission of a completed Suppliers Request for Engineering Approval, SREA. For parts and components using Ford Engineering Material Specifications, all
24、samples tested to the specifications for Design Verification (DV), Production Verification (PV) and Production Part Approval Process (PPAP) sign off must be kept until Job 1. 4.3 RESTRICTED SUBSTANCE MANAGEMENT STANDARD Substance restrictions imposed by regulations or Company direction applies to th
25、e materials addressed by this document. The restrictions are identified in the Restricted Substance Management Standard WSS-M99P9999-A1 which is updated yearly. It is the suppliers responsibility to comply with this standard on a continuing basis through IMDS and or GMAP reporting. 4.4 ENVIRONMENTAL
