SCOPE:The mater
2、ial defined by this specification is a 3 ply laminated deadener,composed of asphalt rubber mastic and an antiblocking agent on bothsurfaces to prevent blocking during shipping and storage. TheESB-M5G19-C1 and ESB-M5G19-F1 materials have polyethylene film onone side and kraft paper on one side. The E
3、SB-M5G19-C2 and ESB-M5G19-F2 have polyethylene or polyester film on both sides.2. APPLICATION:This specification was released originally for materials used as floorpan deadeners. The ESB-M5G19-C1 and ESB-M5G19-F1 are generallyused in thicknesses of 0.1 in (2.5 mm) and 0.08 in (2.0 mm), bothwith and
4、without fiber pads as a deadener and sound barrier.The ESB-M15G19-C2 and ESB-M5G19-F2 are more pliable and can be usedin thicknesses down to 0.06 in (1.5 mm) where lower weight orgreater flexibility is desired.3. REQUIREMENTS:ESB-M5G19-C1 and ESB-M5G19-F1 were originallydesignated ESB-M5G19-C and ES
