150℃ Halogen FR TPEE Compound

YHS62025D-150

150℃ oil-resistant halogen-containing flame-retardant crosslinked polyester elastomer cable compound (YHS62025D-150) uses block copolymer TPEE with polyester hard segments and polyether soft segments as base resin. High-efficiency flame retardants, antioxidants, crosslinking sensitizers and other processing aids are incorporated, followed by mixing, plasticizing and pelletizing. It delivers high heat resistance, high strength and solvent resistance; custom hardness, weather resistance, UV resistance and matte surface are optional. This halogen-containing grade features high flame retardancy, high strength and oil resistance for jackets of high-oil-resistant locomotive cables, oil well cables and equipment wires.

Recommended

Extrusion Process

When the storage time is long or the environment is humid, or the product surface requirements are high, the pellets can be dried in a hot air hopper at 60-70 ℃ for 1 to 2 hours before use.

It is recommended to use screw extrusion with L / D≥25 and compression ratio of 1.5 ~ 2.0: 1. The screw should be cleaned before extrusion to ensure the cleanliness of the product. It is recommended to use 80 mesh or 100 mesh filter to avoid impurities in the extrusion process, while ensuring the melt pressure to obtain a good appearance and material compactness. Because the difference between the actual temperature of the melt and the value indicated by the temperature control meter varies with the type of extruder, users are requested to choose the appropriate temperature according to the specific situation of the extruder used. The following temperatures can be used as a reference for commissioning:

Position	Cylinder I	Cylinder II	Cylinder III	Cylinder IV	Cylinder V	Head and mold
Temperature	150±10	175±10	180±10	185±10	190±10	200±10
