PVC material is polyvinyl chloride material, which is currently the second largest general-purpose plastic in production and the most widely used plastic. PVC itself is also a colorless and transparent hard material, but it is much more brittle than PC, and its transparency is not as good as that of PC. Other The mechanical properties are also far from PC. But PVC can be added with a lot of plasticizers, and after adding, it can be made into soft PVC. The so-called hard PVC is the polyvinyl chloride PVC plastic with less than 5 kg of plasticizer added in 100 kg of PVC resin powder.

HDPE features are as follows：

1, HDPE has excellent resistance to most life and industrial chemicals, it can resist strong oxidant, acid, alkali salt and organic solvent corrosion and dissolution.

2, HDPE does not absorb moisture and has good waterproof steam property, can be used for moisture-proof and impermeable or packaging.

3, HDPE has good electrical properties, especially high insulation dielectric strength, so that it is very suitable for wire and cable. Medium to high molecular weight classes have excellent impact resistance at room temperature and even at temperatures as low as -40F.

4, HDPE has good machinability and heat sealing.

5, HDPE has a high degree of paper-like, crisp and open, hardness of LDPE film 4~5 times. Its surface hardness, tensile strength, rigidity and other mechanical strength close to PP, tougher than PP.

6, HDPE is non-toxic and odorless, can also be used for food, clothing, knitwear and other packaging materials, affordable, low price
