LSTT Low Shrink Temperature Heat Shrink Tubing

LSTT is a low shrink temperature general purpose polyolefin tubing, designed for commercial applications where a low shrink temperature is an important factor. LSTT will start to shrink at temperatures over 70°C and will fully recover at 95°C.

LSTT Product Overview

LSTT is a highly flexible, low-temperature heat shrink tubing.  Its low shrink temperature not only offers ultra fast recovery for maximum efficency but also allows for use on or near delicate and temperature sensitive materials such as PVC jacketed wires and cables.  Although the product is not flame-retardant, LSTT does meet the automotive flame propagation standard MVSS 302.

The Raychem range of heat shrinkable products  (now owned by TE Connectivity) are world renowned as the market leading brand and these products are the standard bearer, offering the best performing and highest quality product available.  The LSTT product is the original low shrink temperature heat shrink tubing and although there are now many alternative copies available, none of these have the track record and performance history of LSTT.

Undoubtedly, LSTT is ‘The King’ of the low shrink temperature heat shrink products.
