BRIFLON™ HEAT SHRINKABLE PTFE
        TUBINGS PER MIL-I-23053/12


SH250, SH254 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 coeff-
icient of friction.   High mechanical strength yet flexible (low temperature flexibility -67°C).  Their
excellent electrical characteristics remain stable throughout their electrical range.  Longitudinal
change of 20% with full shrinkage.  Color: Natural (translucent).



SH250 (SHRINKABLE PTFE) 1.5:1    MIL-I-23053/12    250°C

SH250: an extruded modified TFE (PolyTetraFluoroEthylene) tubing, with a continuous operating
temperature of +250°C (550°F).  SH250 will shrink when heated to 621°F. Shrinkage ratio — 1.5:1.  Used
wherever hi-temperature protection required.  Applications: Protective covers in corrosive environments,
protection for electronic components, cable jacketing covers on immersion heaters, heat exchangers,
light duty bearing surfaces, roll covers.   MIL-I-23053/12 Class 2** or Class 3, MIL-DTL-23053/12, AMS-DTL-23053/12.

 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-flammable, non-corrosive, and offers all of the other outstanding electrical, chemical, and
mechanical properties of
PTFE.  Std. Color: Natural (Clear)
