Product Overview: Sheath material is used for outer protection of cables. Common materials include PVC, PE, and rubber, among which PE has the best weather resistance and rubber flexibility, making it suitable for complex environments.

Key performance indicators (for reference only, not used as procurement standards)

• Tear resistance: PE ≥ 50N/mm, rubber ≥ 80N/mm (ASTM D624 standard).
• Weather resistance: PE has passed the 3000 hour QUV test, with a color difference Δ E ≤ 3
• Flame retardancy: Flame retardant PE has an oxygen index of ≥ 28 (GB/T 2406 standard).

Application scenarios

• PE sheath:outdoor cables (such as YJV22), submarine cables.
• Rubber sheath: drag chain cable, robot cable.

Procurement precautions

• Environmental requirements: RoHS and REACH reports are required for exports to the European Union.
• Process adaptation: Confirm that the sheath material matches the extruder temperature (such as PE processing temperature of 180-220 ℃).
• Inventory management: The shelf life of polyvinyl chloride resin is 2 years, the shelf life of PE is 3-5 years, and the shelf life of rubber is only 6 months to avoid large-scale hoarding.
