Professional FAQs

What is blue heat shrink tubing used for?
Professionals use blue heat shrink to insulate and identify neutral wires in electrical installations. It also provides mechanical protection and strain relief for cables and connectors.

Is this tubing suitable for permanent electrical installations?
Yes – it’s made from professional-grade polyolefin that’s flame-retardant, RoHS compliant, and designed for permanent wiring, control panels, and industrial systems.

What temperature should be used for shrinking?
Apply even heat at approximately 80 °C using a heat gun. This ensures smooth recovery and a tight, uniform finish without cracking.

Can blue heat shrink be used in industrial or automotive environments?
Yes. It offers excellent resistance to oils, fuels, and hydraulic fluids, making it ideal for workshop, plant, or vehicle wiring.

Why choose mini reel packaging?
Mini reels keep tubing clean, organised, and ready to use – perfect for electricians and engineers who need reliable, portable insulation on the go.
