#ST250 Daflex Stretch-N-Seal Rubber Non-Heat Shrink Tape


Product Options

Catalog Number:
Package Type:
Description: DAFLEX ST250 cold shrinking Stretch-N-Seal tape requires no heat to provide a secure covering where the size and or shape of an object does not permit the use of shrinkable tubing. Simply remove 2" to 3" of tape from the roll, remove the liner, stretch tape to 50% of the supplied width and wrap it spirally around the object , with a 50% overlap. In minutes the tape will react with itself to form a mass which will provide protection from moisture, most chemicals, over 1KV per mil and will operate from -40°C to 130°C.
U/L Recognized: 100°C; Weather Resistant; Cold Resistant.

DAFLEX ST250 can be removed easily without leaving any residue, since the cold shrink tape does not use a mastic or adhesive liner. Shelf-life is over 5 years. It is helpful for covering, sealing, splicing, holding bundles, joining and repair applications.
