SHTF is made with a combination of PTFE and FEP Fluoropolymers. The inner wall is made of FEP and the outer wall of PTFE. When the tubing is heated, the PTFE begins to shrink down tightly over the FEP. The FEP inner wall melts and flows -squeezes- into and around the item covered, creating a solid or near solid encapsulation.
The fit is so tight that it is safe against most environmental hazards involving pull or vibrations. It can be used as a strain relief, or moisture-proof covering for wires, connectors, terminals, splices, electronic devices, etc. SHTF is non-flammable, non-corrosive, and offers all of the other outstanding electrical chemical, & mechanical properties of Fluoropolymers. OPER. TEMP.: -85°F to +450°F
