Standard heat shrinkable tubings
-General
Heat shrinkable tubings are radiation cross-linked flame-resistant heat-shrinkable tubing. They are rercognized and UL and CSA 125°C, 600 V, with UL VW-1 and CSA OFT flame-retardancy ratings.
-Features
Operating temperature -55 ~ 125°C
Minimun shrink temperature 90°C
Shrink ratio more than 50% in the radial direction
less than 7% in the axial direction
Excellent mechanical, electrical, chemical properties, oil resistant
Capable of shrinkable comparatively low temperature as well as hot air or steam
Superior heat and cold, flame resistant properties
-Applications
Insulation of terminal wiring for electric and electronics equipments
Insulation protective covering for wire connection joint and connecting terminal
Insulation protection for resistors, capacitors and other parts
