Typical values were tested on the 1mm sample strip by squeezing film extrusion after mixing compound of A & B (at percentage of95:5) and be boiled in 90℃ water for four hours.
*Especially, these typical values were tested by press moulding sample under the condition of 180±2 ℃, 15min, and pressure over 15Mpa, then boiled in 90℃ water for four hours.
Recommended Processing Technique
1. Extrusion Equipment
Most extruders for PVC and PE suit for 4214/4214B.
The recommended equipment and processing technique is as following.
Ratio of length and diameter 18—25:1
Diameter 45—120mm
Ratio of compressing 1.5—3.5
Ratio of elongation 1:1.0—1:1.5
Filtering mesh 40/60/40
2. Extruder processing temperature and other related settings
Temperature Setting: Specific processing temperature should be based on different equipment and pressing conditions, reference settings are as following:
Feeding section（℃） | Compression Section（℃） | Measurement Section （℃） | Die head and Mould （℃） |
150~165 | 165~175 | 175~190 | 190~200 |
Die head setting: Squeezing extrusion style, half-tubing extrusion style and tubing extrusion style
Cooling water temperature: Should not be less than 25℃,gradual cooling water tank is recommended.
3. Crosslink
After extrusion and cooling, the cable can be crosslinked by immersed in hot water (90℃) or exposed in low pressure vapour. The time required for crosslink is based on the thickness of the insulation and the coil size, the thicker the insulation and the greater the coil size, the longer the crosslink time required. The crosslink time can be calculated according to the equation of 4hr/mm for 90℃.
