Low-smoke halogen-free flame-retardant insulation material for European standard power cords | YHS70016J | Meet the requirements of HD21. 14 standard, good anti-blocking and insulation performance |
Low-smoke halogen-free flame retardant sheath material for European standard power cord | YHS70016H | Meet the requirements of HD21. 14 standard, anti-blocking, soft, good elasticity, wear resistance |
Low-smoke halogen-free flame-retardant cable material for European standard power cords (YHS70016 series) is based on polyolefin elastomer, and is added with flame retardant, smoke suppressant, antioxidant and processing aid, etc. Made from grain. It not only has excellent physical and mechanical properties, electrical properties, flame retardant properties and processing performance, but also has high environmental protection features such as halogen-free and low smoke generation. The cable prepared from this material feels soft to the touch, has good resilience, and is wear-resistant.
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 |
