Frequently Asked Questions

What is the shrink ratio of your heat shrink tubing?

We produce standard 2:1 and high-expansion 3:1 dual-wall adhesive-lined shrink sleeves. The 3:1 ratio allows easy fitting over irregular shapes and connectors, shrinking tightly with inner hot-melt adhesive that flows to create a waterproof seal.

Is your heat shrink tubing flame retardant and waterproof?

Yes. Our polyolefin insulation shrink tubing is flame-retardant and rated for electrician and industrial wiring applications. Dual-wall versions include an internal adhesive liner that melts during heating to form a moisture-proof seal.

Can you supply heat shrink tubing in custom sizes and colors?

Yes. Custom inner diameter, wall thickness, cut length (pieces or spools) and colours are supported for distributor and OEM requirements. Most items start at 100 meters.
