DECEMBER 2010 Page 2 of 4 4.2 Manufacture The polyisocyanate foam is a polyurethane modified cellular plastic and shall be processed as a rigid foam in bulk form for fabrication into molded parts. 4.3 Description This product is manuf
10、actured as a high performing energy/impact absorbing rigid foam to be used behind the bumper fascia application on Navistar trucks. Product may come with or without adhesive for mounting. If a release liner is used with adhesive, the paper shall release easily and cleanly from the foam. 4.4 Color Sh
11、all be light blue unless otherwise specified. 4.5 Property And Performance Requirements 4.5.1 Density: (ASTM D 3575, Suffix W, Method B) Type I - 0.043 g/cm(2.7 lb/ft) min 4.5.2 Compression Strength: Vertical (ASTM D 1621) Type I - 248 kPa (36 PSI) Temperature Compression Value 25% Compression Value

Specimens will not dis
14、solve, delaminate or exhibit other objectionable characteristics. 4.8 Pressure Sensitive Adhesives Generally, adhesives supplied to this specification only need to adhere until assembly is complete. In those cases where better, more durable performance is required, then the adhesive shall meet TMS-6
15、929. In both cases the adhesive needs to survive the environment the impact foam is intended for without causing any detrimental effects to the performance of the impact foam. Please contact Materials Engineering if further guidance is required. NUMBER: TMS-6513 TITLE: Impact Energy Absorbing Foam R
