Additional Information
Processing Techniques/Extruding techniques
It is recommended to use a low smoke zero halogen special screw,with a length to diameter ratio of L/D=20~25 and a compression ratio of1.1~1.3. Because the actual temperature of the melt is related to the lengthdiameter ratio, compression ratio and screw structure of the extruder, theappropriate extrusion temperature should be selected according to the specificsituation of the extruder.
The recommended setting temperatures for each zone of theextruder are as follows:
Zone Z1 Z2 Z3 Z4 Head Die
Temp. (℃) 120 130 140 140 150 150
Using Method
(1)When using this product, mix the A and B components evenlyand drop them into the hopper.
If color is required, the cable factory can use polyethylenebase color masterbatch and materials
within 8 hours after unpacking.
(2)This product should not be shut down for a long time. If itis shut down for a long time, it is
recommended to stop and clean the screw before starting upagain.
(3)To ensure sufficient crosslinking of the material, it isrecommended that the cable be placed in
a 70°C water bath or steam room for 6~8h, or at a constanttemperature and humidity (23°C, 50%)
for 7 days. The specific placement time is adjusted according tothe thickness of the product and
the crosslinking degree of the material, so as to meet theperformance requirements of the cable.
