Fit Tolerance Limit Battery Compression Pads
Fit Tolerance Limit Battery Compression Pads Microcellular Foam Polypropylene Resin Description Flame-retardant polypropylene microcellular foam (MPP) is a porous foam material made by using polypropylene (PP) as the substrate to form a large number of micron-sized bubbles in the body through clean supercritical carbon dioxide technology. Ingredients Polypropylene resin, flame retardant, air (Note: The CO2 gas in the bubble has been replaced by air before leaving the factory)
