DPE board (high density polyethylene sheet) melting point is about 130 ℃. It has good mechanical strength. It has good heat resistance and cold resistance, good environmental stress crack resistance. It is advised that the range of melting temperature is 200-250℃. The melting temperature is 220℃-260℃. The relative density is 0. For materials with larger molecules, 941-0, it has higher rigidity and toughness and good chemical stability. It can use carbide cutter tool or diamond cutter to cut. Dielectric properties. Hardness is about 30-45HRC.
