Package: DCH31A in stripe or pellet form can be packed in carton box with PE film inside or according to customer’s requirements. The compound should be stored in clean, dry, draughty warehouse.

Product description:

I. IllustrationDCH31A based on CPE and also blended with other additives has heat -resistance, flame-retardant,oil-resistance, cold-resistance, weathering-resistance, and good mechanical properties after cured. It is in accordance with XH-31A Type Jacket in GB7594-87 standard, i.e. heavy-duty flame-retardant rubber jacket under 90℃. Cable jacket made by DCH31A is the first ideal substitution of CSM Compound because of its excellent properties, good extrusion rubber surface and lower cost.

II. ApplicationDCH31A with excellent heat-resistance, ozone-resistance,smooth extrusion, longer-term storage performance, etc, is suitable for Medium Voltage Rubber Cable Jacket instead of CSM Compound.

Processing conditionContinuous vulcanization production method is preferredCompression ratio of extruder: 1.1:1-1.5:1Length-diameter ratio: 6:1-16:1(hot feed is suggested if lower than 10:1)Temperature of extruder: 60-80℃Temperature of curing pipe: 165-185℃
