Features

Good mechanical properties, electrical properties, strong acid and alkali resistance, good chemical stability, but low softening point. Suitable for making thin plates, wire and cable insulation layers, seals, etc.

Forming characteristics

1. Amorphous material, low moisture absorption, poor fluidity. In order to improve fluidity and prevent air bubbles, the plastic can be dried in advance. The mold pouring system should be thick and short, the gate section should be large, and there should be no dead ends. The mold must be cooled and the surface should be chrome-plated;

2. Due to its corrosive and fluid characteristics, it is best to use special equipment and molds. All products must be added with different types and quantities of additives as required;

3. Extremely easy to decompose, it will be more easily decomposed by contact with steel and copper at 200 ° C, and corrosion will escape during decomposition. Irritating gas. Small molding temperature range

4. When using the nozzle of the screw type injection machine, the hole diameter should be large to prevent dead angle stagnation. It is best not to have inserts.
