Which materials are very important in the EV Battery Pack structure? Microcellular Polypropylene Foam Pad compress pad gap pad

Description:

Microcellular Polypropylene Foam Pad has an impressive compression set — the ability of a material to resist permanent deformation under compressive loads in the battery. The performance of specially engineered polyurethane- and silicone-based foams will outlast the lifespan of the battery, which isn’t true for other potential materials solutions such as other elastomers. Another advantage is foam’s remarkable operational temperature range, much larger than most other rubbers. 

• Fire retardant grade reaches HF-1 (t> 10 mm)
