Flame retardant polyethylene cable compound

YHS62019

Flame retardant polyethylene sheath material (YHS62019) is made of high-purity polyethylene as the base material, adding halogen-free high-efficiency flame retardants, antioxidants, lubricants and other auxiliary agents, and mixing and plasticizing granulation. This product not only has excellent flame retardant properties, but also has good extrusion processability. It has been proved by environmental stress and thermal stress cracking test that the material has excellent resistance to cracking. It is suitable for flame retardant 35KV and 35KV and above Insulation material for power cables.

Recommended

Extrusion Process

When the storage environment is wet or the production surface is required to be high, the particles can be dried in a hot air hopper at 70℃ for 1-2 hours.

It is recommended to use a low compression ratio screw extrusion with a compression ratio of 1.2-2.0:1.Before extrusion, the screw should be cleaned to ensure the cleanliness of the product. It is recommended to use 80 mesh or 100 mesh filter screen to avoid impurities in the extrusion process, and to ensure the melt pressure to obtain a good appearance and material density.As the difference between the actual temperature of the melt and the indicated value of the temperature control table varies with the type of extruder, the user is requested to select the appropriate temperature according to the specific situation of the extruder used.The following temperatures can be used as reference for start-up and commissioning:

Position	Cylinder I	Cylinder II	Cylinder III	Cylinder IV	Cylinder V	Head and mold
Temperature (℃)	140±5	170±5	175±5	180±5	185±5	190±5
