Material properties

Low density, strength and stiffness, hardness and heat resistance are better than low-pressure polyethylene, can be used at about 100 degrees. Good electrical properties and high frequency insulation are not affected by humidity, but become brittle at low temperatures, not resistant to aging Suitable for making general mechanical parts, corrosion-resistant parts and insulating parts

Molding performance

1. Crystalline material, low hygroscopicity, prone to melt fracture, long-term contact with hot metal easily decomposed.

2. The fluidity is good, but the shrinkage range and the shrinkage value are large, and it is easy to produce shrinkage holes, dents and deformation.

3. Cooling speed, casting system and cooling system should be slowly cooling, and pay attention to control the molding temperature. The material temperature is low direction direction is obvious. Especially low temperature and high pressure, mold temperature is less than 50 degrees, the plastic parts are not smooth, easy to produce Poor welding, leaving marks, warpage easily occur above 90 degrees

4. The plastic wall thickness must be uniform to avoid lack of glue, sharp corners, to prevent stress concentration.
