This series of products as long as the polyolefin resin material , the environmental protection or halogen-free flame retardants, antioxidants and other additives by mixing, plasticizing and granulating made by SGS company testing materials , heavy metals and halogens ( environmentally friendly material does not detect halogen projects ) and other environmental control substances comply with ROHS environmental directives.
First, the implementation of standards
UL1583, UL66, ISO6722, ISO4141, GB/T8139
Second, the characteristics and uses
The series not only has excellent low smoke zero halogen flame retardant properties, and excellent extrusion performance, in ordinary PVC extrusion processing extruder , as long as the normal cooling device , extrusion processing speed can be accelerated. This series of product performance than similar foreign products . This series of products for a variety of electronic control lines , automotive cable, phone cord.
Third, the extrusion process
Moisture-proof plastic bags such as found in the failure , to be dried before use , using the blowing method , the drying temperature is 65 ℃, for at least 2 hours , heat the material to the extruder is appropriate. Available L/D18-25 the extruder screw compressor is relatively low, the feeding amount is large. Extruder each district should have a cooling control system, the melt temperature does not exceed 170 ℃. Since the difference between the actual temperature of the melt and the temperature table indicates the value varies between different types of extruder vary , each user should be used according to the specific circumstances of the extruder , selec the appropriate temperature.
The following temperatures can be used as reference for commissioning
Fourth, storage and transportation
Packing : net weight 25Kg or 1000Kg, moisture-proof plastic composite vacuum bag, packaging kraft paper bags or bags with .
Transport and storage : cable during transport should not be the sun and rain . It should be stored in clean, cool , dry , ventilated warehouse. Carry over
Process should light moving light . Cable shelf life of one year.
Fifth, the physical and mechanical performance indicators
