Q: How do I apply polyolefin heat shrink tubing?

A: Simply slide the appropriate diameter tube over the wire or connector, then apply gentle heat (using a heat gun, lighter, or hair dryer) until the tubing shrinks snugly to 1/2 its original diameter. Full shrinkage is achieved at ≥120°C. Cut to your desired length beforehand using scissors or a sharp knife.

Q: Is this heat shrink tubing safe for electrical wiring?

A: Yes. These tubes are made from CE-certified, flame-retardant polyolefin with a dielectric strength of 15 KV and a tensile strength of 10.4 MPa. They are designed to provide reliable electrical insulation for low-voltage wiring applications and are rated for an operating temperature range of -55°C to +125°C.

Q: Can this tubing be used for automotive applications?

A: Absolutely. The wide operating temperature range (-55°C to +125°C) and flame-retardant properties make this polyolefin heat shrink tubing well-suited for automotive wiring harnesses, connector protection, and cable repairs.
