When assembling, some electronic components are of big size, they ask for rubber wire harness sleeve with good extension performance. Under this situation, in order to meet the assembling demand requested by cable assembly lines, the rubber wire harness boots need to be extended to 4-6times bigger to ensure the cables are easy to go through.

The extensibility of the rubber wire harness sleeve mainly depend on the tensile strength and elongation of the rubber material it used. In this case, the right formula of rubber material is important to guarantee the final rubber wire harness boots are capable to meet customized cable assembly demand.
