PTFE Heat Shrink Tubing 2:1 • Fractional

PTFE 2:1 Fractional Heat Shrinkable Tubing possesses excellent characteristics for use in high temperature applications, corrosive environments and as an electrical insulator. PTFE Heat Shrink Tubing offers the ultimate performance with the highest continuous working temperature of all Fluoropolymers. Applications for PTFE Shrink Tubing in Fractional Sizes include insulating, terminating, moisture sealing, splicing, and wire bundling. Heat Shrink PTFE in colored tubing can also be a great visual for coding wires. See the Data Sheet for a summary of PTFE Heat Shrinkable Tubing & its properties.

PTFE possesses the lowest coefficient of friction of all Fluoropolymers.

PTFE is a non-wetting, self-lubricating material.

PTFE tubing can be sterilized chemically and is auto-clavable.

PTFE Heat Shrink tubing is made to AMS-DTL-23053/12 ( Mil -I- 23053/12 )

Available in 3 different wall thicknesses : Standard Wall , Thin Wall & Industrial Wall

Shrinking Instructions :

PTFE Tubing is the most difficult of the fluoropolymers to shrink because of the extreme shrink temperature. The most reliable way to shrink PTFE is in a controlled oven environment. Shrinking can be accomplished with a heat gun or open flame but it is not recommended because of the tendency to overheat the area in a single area while the remainder of the material remains to cool to shrink.

Extreme caution must be exercised in heating the PTFE during the shrinking process. The PTFE Tubing must be heated evenly to the gel state to insure complete recovery. PTFE shrink tube will become completely clear when it reaches it gel state at about 624°F. After the material has reached its gel state do not continue to heat, the material is now ready to begin the cooling and shrinking phase. PTFE will start to recover once the cooling process has begun and the material comes out of its gel state. Once the material has completely cooled the PTFE’s appearance will be its normal milky white color.

PTFE Heat Shrink Tubing will tend to split longitudinally if tubing is not allowed to recover to about 75 % of its expanded diameter or if it is over heated during shrinking.
