PE is also called polyethylene, polyethylene is divided into low molecular weight and high molecular weight two kinds, low molecular weight is generally liquid, colorless, tasteless, insoluble in water, density of 0.92 g/cm 3, can do lubricating oil and paint; High molecular weight is generally solid, milky white, thermoplastic, hand feel wax, density between 0.92 ~ 0.96 g/cm 3.
Polyethylene has good corrosion resistance and insulation performance. High density polyethylene has the characteristics of rigidity, hardness and mechanical strength, can be used as containers,
Pipes, and high frequency electrical insulation materials, used in radar and television. It is insoluble in water, water absorption is very small, is to some chemical solvents, such as toluene, acetic acid, and so on, only at 70 degrees above the temperature to slightly dissolve. However, the microform polyethylene can melt or solidify between 15℃ and 40℃ with the change of temperature. When the temperature rises, it melts and absorbs heat. When the temperature drops, it solidifies and gives off heat. And because it absorbs very little water, is not easy to damp, insulation properties, so it is a good building material. The fine polyethylene mixed in cement can be used as walls and floors, using its characteristics of endothermic melting and exothermic solidification at normal temperature, when the room temperature rises, it melts and absorbs heat; When the temperature drops, it solidifies and gives off heat. This will keep the temperature of the room stable. Therefore, it is a good heat storage material.
The strength of
Polymer Polyethylene fiber is the highest synthetic fiber, its strength can reach the same specification steel wire 1.5 times, and the elongation is very low, and can be comparable to the fracture elongation of metal wire. The rope made with it has the characteristics of ultraviolet radiation resistance, salt water resistance, acid and alkali resistance, fatigue resistance, climate temperature difference resistance, prolong the service cycle, etc.
Polymer polyethylene cable with super strength and special high quality performance has become the preferred products in special industries, product applications: national defense, special ships, offshore oil, ocean transportation and other fields.
