2. Description of Polyolefin:
Chemical cross-linkable POE compound for cables and wires, based on POE resin, is produced and pelletized by special technology with adding special stabilizing agent, modifier, halogen-free flame retardant, cross-linking agent and other special additives. The compound has well thermal deformation resistive and mechanical properties. It suits the cables and wires manufacturers who have rubber production lines, and need not irradiate.
3. Processing of Polyolefin:
The compound could be processed in common rubber extruder, and the recommended processing temperature is 100°C.The user could adjust the temperature properly according to extruder and wires and cables surface status.
Vulcanize processing of the compound could refer to rubber. The details of extrude speed, Vulcanize temperature and time could be adjusted properly according to the equipments and cross-linked status.
4. Storage and transport of Polyolefin:
Packing: 25kg/bag, PE membrane inside bag and craft outside bag.
Avoiding in direct sunlight and weathering.
Storage place should be clean, cool, dry and ventilated.
