Heat shrink tubing 2:1, UL 224
These heat-shrinkable sleeves have a 2:1 shrink ratio and are made from the flame-retardant material polyolefin and are suitable for an operating temperature of -55 to +125 degrees Celsius. Many different colour variants are available, for which UL approval applies (with the exception of transparent).
The heat-shrink tubing also has good resistance to chemicals and can withstand extreme temperatures in the operating temperature range without splintering or breaking. Almost all variants are also flame retardant.
