2、Global Technologies, LLC Page 1 of 2 POLYURETHANE (PUR) FOAM, RIGID, 37 kg/m3ESB-M2D356-B 1. SCOPE The material defined by this specification is a fast curing, two part, foamed-in-place polyether polyurethane foam. This foam is formulated to be free of chloroflourocarbons (CFC). 2. APPLICATION This

3、specification was released originally for material used in the A and D pillars of the 1992 Crown Victoria to seal against wind noise and dust. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS

4、 Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.4 TEST SPECIMEN The following material properties shall be determined on specimens taken from molded test blocks or parts where possible. The specimen shall be free

9、d-point and parallel to a side of a 150 x 150 x 25 mm test sample. Expose in a mechanical convection oven as indicated. 3.4.5 Aged Weight Loss, max 7% (Average of 3 test samples) Test Method: Weigh a 100 x 100 x 25 mm sample to the nearest mg (W1). Expose for 24 h at 120 +/- 2 C in a mechanical oven

10、. Remove sample and reweigh (W2) after 30 minutes in a desiccator. % Weight Loss = (W1- W2) x 100 W13.4.6 Cold Slam Resistance No adhesion (FLTM BV 101-02, 10 cycles, failure or foam 3 test samples minimum) cracking Test Method: .
