Frequently Asked Questions
Frequently Asked Questions
What is Standard Heat Shrink Tubing used for?
Standard Heat Shrink Tubing is used for electrical insulation, cable branch covering, terminal protection, harness finishing and sealing or strain relief when the selected construction fits the project.
How should I compare Standard Heat Shrink Tubing options?
Compare shrink ratio, recovered size, wall type, adhesive requirement, environment, installation process and the validation standard required by the customer.
What should I send for Standard Heat Shrink Tubing samples?
Send the cable or terminal size, starting and recovered diameter target, length, color, sealing requirement, environment and expected assembly method.
What is the dielectric strength of standard heat shrink tubing?
WCW Flex standard heat shrink tubing has a dielectric strength of >=15 kV/mm with a UL 224 rating of 2500 V / 1 min no breakdown. It provides reliable electrical insulation for wire splices, terminal covers and general-purpose insulation after recovery.
What shrink ratio and temperature does standard heat shrink tubing support?
Standard heat shrink tubing typically has a 2:1 shrink ratio with an initiating shrink temperature around 84 C and full recovery around 125 C to 135 C. It is rated for continuous use at 125 C. For higher temperature or higher shrink ratio needs, consider 150 C heat shrink or 3:1 / 4:1 dual-wall tubing.
When should I choose standard heat shrink over dual-wall adhesive heat shrink?
Choose standard heat shrink when the application needs electrical insulation and mechanical protection without environmental sealing. Choose dual-wall adhesive heat shrink when moisture, fluid or chemical sealing is required, as the inner adhesive melts during recovery to create a sealed barrier.
