Processing Guide
Recommended Processing Parameters
1
Drying and dehumidification:
- Mix the A and B Component evenly, drop them into the hopper. Please use EVA masterbatch if color required(it should be dried). The material must be use up within 2 hours after unpacking.(It can’t be dried.)Avoid to bring the external water in during the process.
- Screw Type: Suggest to use PVC screw
- Pay-off Speed: Without the effect of smoothness and performance, the faster,the better.
2
Extrusion Temperature：
- Mark: Zone1 130±10 Zone2 160±10 Zone3 180±10 Zone4 180±10 Neck 200±10 Head 200±10
- ontrol the melt temperature of Insulation at 200±10℃ .The extrusion temperature needs to be adjusted according to the actual situation.
3
Cross-linking:
- Natural Cross-link:Temperature 15-25℃,cross-link will be finished around 7days.When temperature is higher than 25℃,cross-link will be finished around 3days.
- Water bath or Steam:Control the temperature around 60℃,cross-link will finished about 4 hours. (the thickness of the test piece is 1mm) Full performance test,water bath (steam)60℃, more than 8 hours, ensure the material is fully cross-linked.
