High Density Polyethylene (HDPE for short) is a non-polar thermoplastic resin with high crystallinity. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial or chemical preservation properties, and will produce chemical and acid resistant fermentation products. Corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride), resistant to acidification and fermentation.<\/p>\n
The market is divided into industrial grade HDPE, food grade HDPE and medical grade, which are suitable for different product grades. This is true even at room temperature and even at a low temperature of -40F. HDPE is a thermoplastic polyolefin produced by copolymerization of ethylene. Although HDPE was launched in 1956, this general-purpose material is still being developed for its new use. Thermosetting plastic \u00abis heated to a certain temperature and becomes a solidified state. Even if it continues to be heated, its state cannot be changed. Therefore, there are environmental issues. And food grade products, this plastic is recommended not to return to the stove.<\/p>\n
Main features<\/p>\n
The unique characteristics of various grades of HDPE are the proper combination of four basic variables: density, molecular weight, molecular weight distribution and additives. Different catalysts are used to produce customized polymers with special properties. The combination of these variables produces HDPE grades for different purposes; achieving the best balance in performance.<\/p>\n","protected":false},"excerpt":{"rendered":"
