The actual advantages of polymer shaped parts: non-adhesion, under the effect of liquid nitrogen, its application temperature can reach below 269 ° C, and it still has a certain impact toughness. Odorless, odorless, non-corrosive, with physiological recycling and physiological adaptability. High wear resistance of polymer shaped parts: because of its distinctive molecular formula, the wear resistance is higher than that of ordinary metal products, polymer shaped parts are 6.6 times of carbon steel, 5.5 times of stainless steel, 27.3 times of copper, 6 times of polyester. PE sheet has the characteristics of resistance to most daily life and industrial grade chemicals. Some types of chemicals can cause chemical corrosion, such as corrosive reducing agents (concentrated sulfuric acid), aliphatic hydrocarbons (xylene), and halide hydrocarbons (carbon tetrachloride). The polymer does not absorb moisture and has good moisture resistance and vapor resistance, and can be used for packaging.
HDPE polymer shaped parts have very good electrical properties, especially the insulation layer volume resistivity is high, making it very suitable for cable and wire. Medium to high molecular weight grades have very good impact resistance, at room temperature and even at low temperatures of -40F, and the characteristic characteristic of various grades of HDPE is the moderate integration of four basically independent variables: relative density, relative molecular mass, relative molecular mass spread, and additives. Different metal catalysts are used to produce polymers with customized unique properties. This independent variable is closely combined to produce HDPE grades for different primary uses; Achieve a good balance in performance. It has excellent organic chemical reliability and can resist the corrosion of most acids, alkalis, organic chemical aqueous solutions and boiling water. Electrical equipment insulation performance is good.
The actual advantages of polymer shaped parts: stable acids, at a certain temperature, concentration value can resist acid, alkali, salt and other corrosive substances and organic solvents.
