Yes. MISCO Australia offers custom cut lengths, coil supply, and bulk quantities for OEMs.

Is batch traceability available?

Yes — batch-level traceability can be provided on request for quality and compliance documentation.

What industries use CB-HFT-600?

Common sectors include switchboard manufacturing, OEM machinery, rail, automotive, renewable energy, industrial electrical, and power distribution.

Can it be used with automated heat-shrink machinery?

Yes. The tubing is suitable for automated heat tunnels and machine-feed systems used for copper bar production.

CB-HFT-600 HEAT SHRINK

CB-HFT-600 is a premium 2:1 cross-linked polyolefin heat shrink tubing designed to deliver dependable electrical insulation, mechanical protection, and colour identification for copper bus bars, cables, and wiring systems. Manufactured using an electron-beam cross-linking process, the tubing provides a thermoset-like structure that shrinks uniformly when heated, forming a tight, smooth, and durable protective layer.

This high-performance tubing offers excellent dielectric strength, strong abrasion resistance, low-smoke halogen-free chemistry, and reliable flame-retardant performance in the black grade (UL 224 VW-1 / F-Mark equivalent). CB-HFT-600 is suitable for both manual installations and automated heat-shrink machinery, making it ideal for production environments and repetitive manufacturing processes.
