Properties Of Hdpe Pipes

chemical property
Polyethylene is resistant to multiple organic solvents and various acids and alkalis, but does not exhibit antioxidant properties such as nitric acid. Polyethylene can be oxidized in an oxidizing environment.
physical property
Polyethylene can be considered transparent in the thin film state, but when it exists in bulk, due to the presence of a large number of crystals inside, it will undergo strong light scattering and become opaque. The degree of crystallization of polyethylene is influenced by the number of its branches, with the more branches, the more difficult it is to crystallize. The melting temperature of polyethylene crystals is also affected by the number of branch chains, distributed in the range of 90 ° C to 130 ° C, with the more branches, the lower the melting temperature. Polyethylene single crystals can usually be prepared by dissolving high-density polyethylene in xylene in an environment above 130 degrees Celsius.
