High density polyethylene (abbreviation: HDPE)

High-density polyethylene (HDPE) is produced using a low-pressure polymerization process. It is linear, has a density of 0.94-0.965q/cm³, and a crystallinity of 80%-95%. It is a white powder or granule.

Compared with low-density polyethylene, its molecular chain has no branches and has an almost linear structure. The molecules are regularly arranged and tightly packed. Therefore, it has high crystallinity and high density, with a relative molecular mass of hundreds of thousands to hundreds of thousands. , the melt flow rate range is narrow.
