On the molding process of ethylene tetrafluoroethylene copolymer

1, the crystalline material, the moisture absorption is small. It can be processed by the usual thermoplastic processing method.

2, poor mobility, easy to decompose, decomposition of corrosive gases. It should be strictly controlled that the molding temperature should not exceed 350 degrees, and the mold should be heated to 100-150 degrees. The resistance of the gating system to material flow should be small. The thin and simple products of 0.7-0.8 mm thick can be formed.

3, transparent granular material, injection molding, extrusion molding. The molding temperature is 300-330 degrees above 350 degrees. High speed and low pressure should be molded, and attention should be paid to mold release.
