The material of the chemical plastic barrel is high-density polyethylene, also called low-pressure polyethylene, or HDPE. This material is not very good for welding with a plastic welding torch. You can use iron to burn and iron the plastic of the same material. You can also use high pressure Polyethylene [LDPE] or EVA plastic is hot-pressed, and this material is softer and has better toughness. This material is currently not glued and can not be adhered to. It is not available all over the world. If it must be adhered, it must be surface treated to be adhered. .
HDPE (High Density Polyethylene): HDPE is a non-polar thermoplastic resin with high crystallinity. The appearance of the original HDPE is milky white, with a certain degree of translucency in the thin section. PE has excellent resistance to most household and industrial chemicals. Certain types of chemicals cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride).
The polymer is not hygroscopic and has good water vapor resistance, and can be used for packaging purposes. HDPE has very good electrical properties, especially high dielectric strength, making it very suitable for wire and cable. Medium to high molecular weight grades have good impact resistance, at room temperature and even at -40F low temperature
Chemical plastic barrels use hollow-grade low-pressure polyethylene. There are many grades of such raw materials. The uses of different production areas and different production areas are different. The quality is also different.
