Quick Details

CAS No.: 9002-88-4	Other Names: High density polyethylene	MF: [C2H4]n
	Grade Standard: Industrial Grade	high density polyethylene: HDPE

Specifications

1. HDPE of high quality low rate
2. Density 0.956 g/cm3
3. Melt mass-flow rate 0.04 g/10 min

High density polyethylene HDPE
1. This kind of corrugated pipe is mainly used for underground water drainage system.
2. It is fully computer/instrument controlled, automatic production line. It features high and stable output capacity, and highly automatic production range is Φ 90~Φ 200mm.
3. Different types of extruders can be selected to match with the production line according to the material properties.
4. The forming system of this line consists of mould and corrugator. The mould blocks can be easily changed and they may have air or water cooling system. The belling process can also be realized on line. High precision cutting can be guaranteed by rotation type cutting machine
