S18 Flexible Chemical Resistant Rubber Heat Shrink Tube
S18 Flexible Chemical Resistant Rubber Heat Shrink Tube
Introduction
A flexible, radiation cross-linked modified rubber elastomeric
heat shrink tube, flame retardant, with excellent high and low-temperature resistance, excellent resistance to solvents, oils, and chemical corrosion. Excellent abrasion resistance and radiation resistance, with a material weight 30% lighter than S10 fluoroelastomer heat shrink tubes. Used for various types of wires and cables in military equipment that require resistance to high and low temperatures, chemical solvents, as well as for insulation of wiring, connection protection or covering, encapsulation of electronic components, and protection of lightweight aerospace wire and cable components.
