Irradiated oil resistant materials for locomotive cables
These materials are made of halogen-free and non-toxic polyolefin resin as the main raw material, with various additives. These materials have good processing performance, excellent physical and mechanical properties, oil resistance, corrosion resistance, mud resistance, flame retardant properties and so on.
Oil, corrosion, mud resistance, flame retardant properties and other characteristics. Made of cable by irradiation crosslinking surface smooth round, feel good, especially suitable for locomotive cables etc. And has the best cost performance.

Note: Due to the different processing equipment, the plasticizing ability of the material is different, so in the initial production trial process, the temperature is only for reference, and the production speed is about 60% of the normal production speed for trial production.
4. Packaging, transportation and storage
Packing: N.W: 25kg bags with inner bag of plastic film moisture-proof bag and outer packing being made of kraft paper composite bag .
Transportation and storage: It should not be exposed to the sun and rain during transport. It should be stored in a clean, cool, dry and ventilated warehouse. It should be handled with care.
5. Shelf life: 6 months
