Processing Guide
Recommended Processing Parameters
1
Use Methods
- 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 2 hours after unpacking.(It can’t be dried.)Avoid to bring the external water in during the process.
2
- Screw Type: equal distance&unequal depth single flight screw
- Compression Ratio：1.5±0.2
- Pay-off Speed: Without the effect of smoothness and performance, the faster,the better.
3
- Cross-linking:Water bath or Steam:Control the temperature around 50℃,cross-link will finished about 6hours. (the thickness of the test piece is 1mm) Full performance test,water bath (steam) 50℃, more than 10 hours, ensure the material is fully cross-linked.

Package, Transport and Storage:
- ①Package：Packed by aluminium foil bag.
- ②Storage：Should be stacked in a clean and dry warehouse.
- ③Valid Period：12 months.
