Processing Guide
Recommended Processing Parameters
1
Mixing:
- Mix the A and B Component evenly, drop them into the hopper. Please use PE masterbatch if color required(it should be dried). The material must be use up within 8 hours after unpacking.(It can’t be dried.)Avoid to bring the external water in during the process.
2
Screw Type & Pay-off Speed
- Screw Type: Single flight PVC screw
- Pay-off Speed: Without the effect of smoothness and performance, the faster,the better.
3
Extrusion Temperature:
- YHS-101W90: Zone1 130±10 Zone2 150±10 Zone3 180±10 Zone4 180±10 Neck 180±10 Head 200±10
- Control the melt temperature of Insulation at 200±10℃.The extrusion temperature needs to be adjusted according to the actual situation.
4
Cross-linking:
- Natural Cross-link:Temperature ≥35℃,Humidity≥90%,cross-link will finished around 24hours.(Above cross-link time based on the insulation thickness ≤ 1mm) Water bath or Steam:Control the temperature around 90℃,cross-link will finished about 4hours. (Above cross-link time based on the insulation thickness ≤ 1mm)
