DUAL WALL HEAT SHRINKABLE
SHTF is made with a
combination of PTFE and FEP resins. 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
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 both PTFE & FEP. OPER. TEMP.: -85°F to +450°F
Color: Natural (FEP-transparent; PTFE-translucent).
SHTF tubings have excellent
resistance to weathering, chemicals (oils, fuels, solvents,
fluids), & fungus, are non-corrosive, low water absorption (.01%), will not burn nor support combustion,
have high dielectric strength (850V/MIL dry), low dielectric constant, & a very low coefficient of friction.
High mechanical strength yet flexible (low temperature flexibility -67°C).
Their excellent electrical characteristics remain stable throughout their electrical range.
Longitudinal change with full shrinkage: 5 - 25%.
++ Fully closes
random lengths of 1 to 3 Ft.
** All dimensions are based on full recovery. RoHS compliant.
