Description

Environment Friendly Flame-retardant Heat Shrinkable Tube is newly developed environment-friendly flame retardant heat shrinkable tube, using specially designed formulation of high polymers through cross-link by electronic accelerator and continuous expansion.

 

Features

Standard: UL 224 vw-1 C-UL CSA C 22.2 OFT

Excellent flame retardant, flexibility, and insulation.

Operating Temperature: -55℃ ~ 125℃

Low shrinking temperature: start at 70℃, and shrink totally at 110℃ - 115℃.

Longitudinal shrink tatio: <5%

quick shrink and stable performance

Size range: 0.8 ~ 180mm (3/64 ~ 5inch or lager), special size are negotiable.

Shrink Ratio: 2:1

Available Color: Black, Red, Yellow, Green, Blue, White, Purple, and Grey.

Special colour can be supplied on request

Do not contain 4 metal elements and 2 kinds of bromide(PBB & PBDE), fully conform to RoHS standard

 

Applications

For various electric insulation and bonding of cables and connectors and widely applied for connecting or end-handling, electric wire, insulating and harness of electric wire, corrosion-proof of metallic rods or tubes, and antenna protection.
