Introduction of molding properties of PE plastics

Tapes PE Pipe Supplier to explain the characteristics of Polyethylene (PE): corrosion resistance, electrical insulation (especially high-frequency insulation), chlorination, chemical crosslinking, irradiation cross-linking modification, glass available Fiber reinforced. Low-pressure polyethylene has a high melting point, rigidity, hardness and strength, low water absorption, good electrical properties, and radiation resistance; high-pressure polyethylene has good flexibility, elongation, impact strength and permeability; Ultra-high molecular weight polyethylene has high impact strength, fatigue resistance and wears resistance. Low-pressure polyethylene is suitable for making corrosion resistant parts and insulating parts;

Molding characteristics:

1. Crystallized material, low moisture absorption, no need to fully dry, excellent fluidity, fluidity is sensitive to pressure, the high-pressure injection should be used during molding, material temperature is uniform, filling speed is fast, the pressure is sufficient. It is not suitable to use a direct gate to prevent shrinkage Uneven, the internal stress increases. Pay attention to the location of the gate to prevent shrinkage and deformation.

2. Shrinkage range and shrinkage value are large, the direction is obvious, easy to deform and warp. The cooling speed should be slow, the mold is set with a cold material, and there is a cooling system.

3. Heating time should not be too long, otherwise, decomposition will occur.

4. When the soft plastic part has a shallow side groove, it can be forced to demould.

5. The melt may break and it is not suitable to contact with organic solvents to prevent cracking.
