Application

Performance

Use Methods

1. Mixing: Mix the Component A and Component B evenly, add them into the hopper. If the color required, use the EVA base materials (the color masterbatch should be dried). The material should be use up within 2 hours after unpacking.(It can’t be dried.)The external water can’t be brought in during the process. 

2. Threaded Rod Type: Low smoke halogen free special screw Compression Ratio： 1.5±0.2 

3. Extrusion Temperature：

Control the melt temperature at 160±10℃. The extrusion temperature needs to be adjusted according to the actual situation. 

4. Double Color Cable:Color line can use Component A and EVA base materials together,without or with a small number of Component B. 

5. Pay-off Speed: Without the effect of smoothness and performance, the faster,the better. 

6. Cross-link: Natural crosslink or Water bath(Steam). Natural Crosslink: Temperature 15-25℃, crosslink will be finished around 7days. When temperature is higher than 25℃, crosslink will be finished around 3days. Water bath or Steam: should control the temperature around 60-70℃ in order to keep it from sticking together, it will finish about 4hours. The thickness of the test piece is 1mm. If thickness >1mm, the crosslink time should be adjusted according to actual situation. Full performance test, water bath (steam) 65 ℃, more than 8 hours, to ensure the material is fully crosslinked.

Package, Transport and Storage: 

Package：Vacuum packed. Transport: Can’t be exposed to the sun or rain, or suffer mechanical damage. Storage：Should be stacked on the backing plate in a clean and dry warehouse. Valid Period：6 months.
