PE sheet is the polyethylene sheet, that is the ethylene polymer, the daily see the PE sheet in our view is like plastic. Because PE sheet has excellent corrosion resistance, so in the chemical industry, construction and other fields have a wide range of uses. PE sheet has excellent resistance to most of the characteristics of life and industrial chemicals. Certain types of chemicals can produce chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance and can be used for packaging applications.PE board specific features are as follows:
1, crystal material, moisture absorption is small, do not need to be dry, excellent mobility of the pressure-sensitive, easy to use high-pressure injection molding, the material temperature uniform, filling speed, full pressure should not use direct gate to prevent contraction Uneven, increased internal stress. Note Select the gate position to prevent shrinkage and deformation.
2, the contraction range and shrinkage value are high, the direction of obvious, easy to deformation warping. Cooling speed should be slow,that has the mold set cold material, and a cooling system.
3, the heating time should not be too long, otherwise it will break down, burns.
4, soft plastic parts have a shallow side of the groove, It can be forcibly removed from the mold..
5, may occur melt fracture, not with organic solvents to prevent cracking.
