Raychem FL2500 Heat Shrink Tubing – Durable Flame-Retardant Solution

The Raychem FL2500 heat shrink tubing from TE Connectivity is a durable, flame-retardant polyolefin heat shrink tubing coated with a flame-retardant adhesive, making it the ideal solution for applications that require or specify full flame retardancy. This heat shrink tubing is perfect for use in the automotive harness market and other demanding environments, where temperature resistance up to 135°C [275°F] for 3000 hours is required.

Optimal Protection Against Liquids and Heat for Safe Applications

During the shrinking process, the adhesive lining inside the tubing melts and fills all openings, creating a complete seal against moisture, oils, chemicals, and other liquids. This makes the FL2500 heat shrink tubing ideal for situations where both flame retardancy and liquid protection are crucial.
