High resistance to abrasion, impact and cold flow
Art.-No. 332-01909 | KYNAR® 3/4-PVDF-CL

TK20 is often used for chemical applications.

This semi-rigid transparent heat shrink tubing has high chemical and puncture resistance.
KYNAR® is extra thin wall tubing with a high temperature performance.
It is self extinguishing and has very good electrical and mechanical qualities.
The transparent material allows visual inspection of covered components.

Calculator tool for Heat Shrink Tubing

for KYNAR® 3/4 - Art.-No.: 332-01909
In selecting the right shrink tubing size it is important to consider to "80:20 rule". Shrink tubing should recover at least 20% and maximum 80% of its potential shrink range.
