Dual Wall Heat Shrink Tubing is used when an extra layer of protection against moisture is needed. It will help to prevent water, chemical and fluids from eroding connections. It is made up of two different layers, the outer layer is a polyolefin heat shrink and the inside layer is made up from adhesive that will melt and flow when heated.
It can bond with many different types of materials completely encapsulating the wiring or cable components to create a moisture resistant seal. This provides better results for the user during assembly.
After the adhesive has cooled down, it becomes and environmental seal, protecting wires or cables from moisture and the environment.
