Irradiated cable materials for special marine cables and corrosion-resistant 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 oil platforms, wires and cables for ships etc. And has the best cost performance.
MODEL: SHFD02-NN-902/903
Relative Standard:
(1) IEC60092-360-2021
(2) Mil-c-24643-1994
Precaution
(1) The performance of the cable mainly depends on the stability of the performance of the materials used for the cable and the cable structure and cable manufacturing process. Therefore, the factory requires the demand side of the cable
Therefore, the factory requires the demand side to verify the cable material before it is put into storage and put into production.
(2) In order to verify the consistency of the formula and performance of our cable materials, for each batch of products provided by our factory, both the supply and demand sides should take 0.3±0.05 kg of sealed samples and keep records.
The supply and demand sides should take 0.3±0.05 kg of sealed samples for storage and record keeping, and supervise them separately, so as to carry out sample verification under the same conditions. The loss of the sealed samples shall be borne by the factory. If the demand side has not sealed samples for preservation, the sealed samples of our factory shall prevail.
Sealed samples shall prevail.
3. Extrusion process
This product has the same (or similar) extrusion process as the low-smoke halogen-free flame retardant polyolefin cable material:

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
