Shanghai Gengyun Industrial Co., Ltd
T-PA001 is a sheathing material made primarily from premium nylon and supplemented with other additives. Its unique formula ensures excellent mechanical properties, termite and rodent resistance, low-temperature resistance, outstanding abrasion resistance, and flame retardancy. Its high hardness and smooth surface make it particularly suitable for sheathing optical and power cables requiring termite and rodent resistance. Cables made with T-PA-7525 meet the termite resistance requirements of the GB2951.38-86 experimental colony method.
Process performance characteristics
When using T-PA001 to extrude wires and cables, an ordinary extruder can be used to obtain an excellent extrusion surface.
The recommended extruder zone temperatures are as follows:
| Location | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Zone 5 | Head | Mokou |
| Temperature℃ | 210 | 225 | 235 | 240 | 240 | 240 | 235 |
