1、Extrusion: CPE has good heat-resistant and processing capability and wide extrusion temperature range, which enhance the safety for processing. For its hardness and viscosity are higher than neoprene, its extrusion temperature is correspondingly higher by 5-10 degrees.
Temperature range for stuffing port: 40-50℃
Temperature range for machine body:55-70℃
Temperature range for machine head: 65-80℃
2、In practical production, according to the difference of extruding machine and cable diameter, the processing parameter shall be adjusted. We will provide relevant technical data to our consumers after they buy our products and send experienced technicians to give on-site guidance.
3、Storage: it can be stored for more than six mouths. And it can still be used even though hardened after long time storage. It should be better for recycling if the conditions allows. Keep away from direct sunlight and raining.
This series rubber compound is produced in accordance with the requirements of national standard GB7594.7-87, and accords with the regulation of mine industry standard MT818-2009. This product can be used to manufacture heavy cable jacket which its conductor allowable work-temperature can stay at 65℃ for a long-term .It has excellent tenacity, oil-resistance, ozone resistance and fine flame resistance, it also can substitute CR rubber compound completely. The manufactured cable, particularly suitable for the long-term poor working conditions, Our red and yellow mineral cable jacket material can satisfy the Standard No.GB12972-91.
This series of rubber compound is produced in accordance with the national standard GB/T7594.9-87. This product can be used to manufacture normal cable jacket which its conductor allowable work-temperature can stay at 85℃ for a long-term. It has a certain oil-resistance, heat resistance, cool-resistance, weather resistance and excellent flame-resistance, also it can be used to manufacture ship cable jacket directly and substitute CR rubber compound completely.
The product is produced in accordance with the requirements of the national standard TICW/01-2009 "rated voltage 1.8/3KV and below twist-resistant flexible cable for wind power generation". It has excellent flame retardancy, low temperature resistance, low smoke, shock resistance and radiation resistance, and can adapt to The special working environment of wind power plants is mainly used for AC rated voltage 12/20KV and below ethylene-propylene insulated chlorinated polyethylene sheathed single-core wind energy flexible cables.
