2、 EPDM FOAM CORE 1. SCOPE The material defined by this specification is a sealing tape consisting of a closed cell foamed mixture of butyl rubber and E.P.D.M, coated on both faces with butyl rubber adhesive, with a release liner on one face. 2. APPLICATION This specification was released originally a
3、s a material for use in conjunction with mechanical retention to seal RIM material of the quarter module to the painted sheet metal in the 1986 Ranger Supercab vehicles. The material is not recommended to be used on the interior glass surface application because it contributes to the formation of li
4、ght scattering film on the glass surface. 3.

Age the assembly as outlined above. Clamp the 90 peel test fixture equipped wi
15、th ball bearing track allowing for a continuous 90 peel angle of the tape from the panel. Place the test panel into the fixture. Insert the extended end of the tape into the crosshead jaw. Initiate jaw separation at a rate of 300 mm/min. Continue the test until all the tape has been removed from the
16、 panel. Record the average peel force. The mode of failure should be reported. 3.13 PAINT COMPATIBILITY No evidence of migration stain, pinholing, blistering or softening of the paint film. Test Method: A 150 mm length of tape shall be placed in contact with a 75 x 230 mm steel panel painted with wh
17、ite ESB-M50J1OO enamel, per ESB-M2P4-A. Use current production paints as identified by the Body and Electrical Product Engineering Office expose the assembly to a temperature of 88 +/- 1 C for 2 weeks. Remove the tape and examine the area directly below and adjacent to the contact area. 3.14 LOW TEM
18、PERATURE FLEXIBILITY No Cracking Test Method: Condition a 150 mm length of tape for 2 weeks at 88 +/- 1 C. Then condition the material in a cold chamber at -29 C for 4 h and bend 180 around a temperature conditioned 25 mm mandrel. 3.15 STORAGE STABILITY The material shall be stored at temperatures b
19、elow 41 C away from all sources of heat and sunlight. Heat greatly accelerates aging. The minimum shelf life will be 6 months if it is stored at 23 +/- 2 C. When these materials are stored at temperatures below 23 C, they shall be conditioned at room temperature 24 h prior to application. Adequate c
20、onditioning permits the material to obtain its optimum application properties. 3.16 RELEASE PAPER The tape sealer shall have a suitable release paper which shall be readily removed, but shall not pull off in shipping and handling. There shall be no transfer of the release agent to the tape after 6 m
21、onths of storage at 23 +/- 2 C.
