Product introduction

Irradiation cross-linked flame-retardant heat-shrinkable products are based on special polyolefin resins. They are added with high-quality and efficient flame retardants, cross-link sensitizers, antioxidants and other processing aids. Granulated, it not only has excellent mechanical and physical properties, electrical properties, flame retardant properties and processing performance, but also has the characteristics of high yield, good appearance, no dripping and so on.

Extrusion process

When the storage environment is relatively humid, or the production surface quality is high, the pellets can be dried in a hot air hopper at 70 ° C for 1 to 2 hours.

It is recommended to use a low compression ratio screw extrusion with a compression ratio of 1.2 ~ 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:
