PYG FOAM developed PO and PF foam, which is applied to the upper, lower, and side panels of electric vehicle (EV) battery packs to provide thermal insulation and protect against shocks and vibrations. PO Foam
PO foam is a type of foam material featuring low compressive stress, slow rebound performance, and good thermal insulation. It can be placed on the upper and lower covers. This strategic placement enables it to effectively absorb shock and vibration, ensuring that the battery remains stable and safe during its operation.
PF Foam PF foam is a high - performance closed - cell material. It is produced by mixing and granulating polyolefin raw materials with various fillers, followed by radiation cross - linking after extrusion and high - temperature foaming. It can be used for buffering around the battery and to ensure the stability and safety of the battery during use.
