Irradiation Crosslinking Cable Material

The special cable material for irradiation crosslinking ethylene-tetrafluoroethylene developed by Chuangmei Science and Technology Research Center is composed of white main material and color master batch, which has excellent high and low temperature resistance, mechanical and electrical properties, easy processing, wide irradiation window, stable and reliable performance and so on. The cables manufactured from our cable materials can fully meet the requirements of MIL-W-22759 and GJB-773 series standards, and have passed the relevant experimental standards for aerospace applications

Melting temperature: 260℃

Screw diameter: 30mm

Extruder temperature (aspect ratio 25): 230℃, 250℃ and 265℃ in the third area of the fuselage; The two zones of the nose are 280℃ and 280℃

Selection standard of die sleeve: tensile coefficient 20-25

For example, for light insulated wires with conductor 19*0.2, the die core can have an aperture of 2mm, and the die sleeve can be selected between 5.5 and 5.8. It is suggested that tensile test should be carried out after extrusion, and the elongation at break should be ≥300%.

The white main material is applied to the extrusion of white insulation or sheath, and the insulation and sheath of other colors can be extruded after mixing the main material and color master batch in a ratio of 100:3.

In order to ensure the quality of products, it is strongly recommended that the main materials and color master batch should adopt the raw materials of our factory.
