Frequently Asked Questions
Frequently Asked Questions
What is Dual-wall Adhesive Heat Shrink used for?
Dual-wall Adhesive Heat Shrink 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 Dual-wall Adhesive Heat Shrink 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 Dual-wall Adhesive Heat Shrink samples?
Send the cable or terminal size, starting and recovered diameter target, length, color, sealing requirement, environment and expected assembly method.
What is dual-wall adhesive heat shrink tubing used for?
Dual-wall adhesive heat shrink tubing has an outer flame-retardant wall and an inner hot-melt adhesive lining that flows during recovery to create an environmental seal. It is used for wire splices, connector backshells, cable repairs, automotive harness sealing and any application needing both insulation and moisture or fluid protection.
What is the dielectric strength of dual-wall adhesive heat shrink?
WCW Flex dual-wall adhesive heat shrink has a dielectric strength of >=15 kV/mm and volume resistivity of >=10^14 ohm-cm. The adhesive lining provides IP-rated environmental sealing while the outer wall provides electrical insulation and flame retardancy.
When should I choose dual-wall adhesive heat shrink over standard heat shrink?
Choose dual-wall adhesive heat shrink when the application needs moisture, fluid or chemical sealing in addition to electrical insulation. Choose standard heat shrink when only insulation and mechanical protection are needed and environmental sealing is not required.
