Specifications
Packaging Details: 20---40kg/packing bag
Delivery Time: 10 days after receiving offical order
Features and applications: Using drawing level Polypropylene as raw material, extrusion forming and meshes tearing by specialized machinery, it mainly used as non-hygroscopic filler for wires and cables.
There are natural white and extremely white colors, and divided into single strand and multi strands, and the former one is used in low level power cable and control cable, while the latter one is used in cross-linked cable.
Physical properties: Light weight, non-hygroscopic, soft and elastic;
Chemical properties: Does not mildew, chemical corrosion resistance, temperature resistance and non-toxic;
Electrical properties: Good high frequency insulation property, high breakdown voltage;
Appearance: Expand into mesh, feels soft, no severe burrs;
Core: Paper tube core in 55mm or 76mm, also can be tailor-made for the special specifications.
