BRIFLONä HEAT SHRINKABLE
        PTFE & FEP TUBINGS

SH250, SH254 & SHTF tubings have excellent resistance to weathering, chemicals (oils, fuels, solvents,
acids, alkalis, fluids , and  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: FEP — 15%: PTFE — 20%.  Color: Natural (FEP-transparent; PTFE-translucent). 

SHTF SHRINKABLE PTFE/FEP

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
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 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, acids, alkalis,
fluids), and fungus, are non-corrosive, low water absorption (.01%), will not burn nor support combus-
tion, have high dielectric strength (850V/MIL dry), low dielectric constant, and 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%.

 SH254 4:1 (SHRINKABLE PTFE)    MIL-I-23053/12     250°C

SH254 tubing can recover to approximately 1/4 of its expanded size when heated to its gel point (621°F-
625°F).  Because of its exceptional shrinkage capability, its recommended that the outside diameter of
the object to be shrunk down upon should not be more than 50% of the expanded I.D. of the size of the
tubing used.  Many sizes conform to AMS 3584 and MIL-I-23053/12 Class 5, MIL-DTL-23053/12, AMS-DTL-23053/12.  
SH254 is non-flamable, non-corrosive, and offers all of the other outstanding electrical, chemical, and
mechanical properties of PTFE.  Std. Color: Natural (Clear)
