Product name, item and use

Product introduction

This kind of material is made of special polyolefin and oil-resistant elastomer as the base material, and it is added with flame retardants, smoke suppressants, cross-linking sensitizers, antioxidants and processing aids, etc., and mixed and plasticized into granules. It not only has excellent physical and mechanical properties, electrical properties, flame retardant properties and processing technology performance, but also has good low temperature and oil resistance, suitable for various standards of locomotive and vehicle cables with oil resistance requirements.

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:
