一、 Different kinds
1. HDPE: High Density Polyethylene ("HDPE" for short), also known as low pressure Polyethylene, is a kind of translucent with high crystallinity and non-polar surfaces to a certain extent. It is a non-polar thermoplastic resin with high crystallinity.
2. MPVE: MPVE double-wall corrugated pipe is a new municipal sewage pipe pioneered and developed by Kangtai Plastic Technology Group in China. It is made of polyvinyl chloride and polyethylene polymerization and has independent intellectual property rights.
二、 Different functions
1.HDPE: has good heat resistance and cold resistance, good chemical stability, but also has high rigidity and toughness, good mechanical strength. Dielectric properties, environmental stress cracking resistance is also good. The hardness, tensile strength and creep properties of low density polyethylene are better than those of low density polyethylene. Good wear resistance, electrical insulation, toughness and cold resistance. Not as strong as HDPE.
2. MPVE: compared with HDPE double-wall corrugated pipe, the comprehensive performance is better than the existing double-wall corrugated pipe products, which is of great significance for the development of double-wall corrugated pipe. And achieve 20-25% material saving, 10-25% cost reduction. Suitable for rain sewage pipe and low pressure rural irrigation pipe.
三、 Different emphasis
1.HDPE: HDPE has excellent resistance to most domestic and industrial chemicals.
2. MPVE: With better water tightness, lighter quality and lower overall cost, it has the tendency to replace HDPE double-wall bellows.
