TPU Polyurethane Cable Compound

YHS62023

This thermoplastic elastomer sealing strip compound adopts SEBS elastomer as base material, compounded with high-performance halogen-free flame retardants, antioxidants and other processing aids, then mixed, plasticized and pelletized. It delivers outstanding mechanical, electrical, flame-retardant and processing properties, featuring high flexibility, high resilience and scratch resistance. Customizable options including varied hardness, weather resistance, UV resistance and matte finish are available. Extruded strips have delicate appearance, smooth surface and comfortable touch. Recyclable, halogen-free, heavy-metal-free and phthalate-free, it complies with EU RoHS, REACH and other environmental directives.

Recommended

Extrusion Process

When the storage time is long or the environment is relatively humid, or the product surface requirements are high, the pellets can be dried in a hot air hopper at 50-60 ° C for 1 to 2 hours before use.

It is recommended to use screw extrusion with L / D≥25 and compression ratio of 1.5 ~ 2.5: 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 (℃)	160±10	175±10	185±10	190±10	195±10	200±10
