2、 RUBBER/POLYURETHANE ESH-M11P19-BFOAM, PRESSURE SENSITIVE FILM WITH BIOCIDE1. SCOPEThis s pecification defines the bond requirements for sponge-expandedcellular rubber or polyurethane foam gaskets of varying densities with apressure sensitive backing, treated with biocide and with or without apolyes

3、ter film backing, to plastic substrates.2. APPLICATIONThis specification was released originally for material for assembliesrequiri ng a gasket with a pressure sensitive adhesive on one side. Thepressu re sensitive adhesive is intended as an assembly aid. It should beused only where the seal is mech

REQUIREMENTS3.1 PEEL STRENGTH, Plastic Membrane to Panel, min(ASTM D 903, except as specified below)Te st Method: Standard test panel to be injection molded smoothsurfaced polypropylene ESB-M4D63-A. Adhere 150

5、mm length of the 12.7mm wide specimen to the test panel using a rubber covered steelroller. (The steel roller must be 83.0 +/- 2.5 mm in diameter and44.5 +/- 1.3 mm in width, covered with rubber approximately 6 mm inthickness having a durometer hardness of 80 +/- 5. The weight of theroller which app

6、lies pr essure to the specimen shall be 2.05 +/- 0.05kg. T he roller should be constructed so that the weight of thehandle is not added to the weight of the roller during use.) Pass theroller, without application of additional pressure, over the gasketle ngthwise once in each direction at the rate o

7、f approximately 50mm/ s. Allow 20 +/- 5 minutes before resuming test. Apply maskingtap e to the top surface of the foam to reduce the friction betweenthe foam surfaces when the specimens are bent 18 0 deg with respect tothemselves.3.1.1 As Received 0.44 N/mm width3.1.2 Heat Aged 0.44 N/mm widthTest

8、Method: Condition the test panel with the specimenadhered for 7 days in a mechanical convection oven at 88 +/-2 C. Allow a 4 h recovery at 23 +/- 2 C and 50 +/- 5 %relative humidity before determining peel strength.ENGINEERING MATERIAL SPECIFICATIONESH-M11P19-BWP 3948-b Page 2 of 3 3.1.3 Humidity Ag
