PTFE Heat Shrink 2:1 • AWG

PTFE Heat Shrink Tubing possess excellent characteristics for use in high temperature applications, corrosive environments and as an electrical insulator. PTFE Tubing has the lowest coefficient of friction among the Fluoropolymer which makes it ideal for applications that need a lubricious slippery material to reduce linear friction. PTFE Heat Shrink Tubing is chemically resistant to all common acids and solvents making it almost 100 % chemically inert. PTFE Tubing has a high dielectric strength over a wide range of temperatures which is why it is an excellent electrical insulator in corrosive environments and high temperature applications.

AWG Heat Shrinkable material is available in three different wall thicknesses just like Extruded PTFE Tubing.  Standard Wall , Thin Wall and Light Wall.

Heat Shrinkable PTFE Tubing carries a Flame Rating of UL94 VO and WV-1 which make it ideal for insulating, terminating, moisture sealing, splicing, wire bundling and electrical applications. Tef Cap can also manufacture Heat Shrink PTFE Tubing for applications where wires or instrumentation needs to be colored coded for identification purposes.

PTFE Heat Shrink Tubing offers the ultimate performance with the highest continuous working temperature of all Fluoropolymers.

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 Mil -I- 23053/12

PTFE Heat Shrink Tubing is a shrinkable Fluoroplastic Sleeve that is commonly used on electrical wires for insulation and abrasion resistance while providing stress and strain relief for connections and joints in wire harnesses. Heat Shrink PTFE is highly versatile and a cost effective way increase your secondary insulation and protection.

Fluoropolymer Sleeving and Shrinkable Tubing is available in a variety of plastic compounds from the basic PVC and Polyolefin to the more expensive Fluoropolymers compounds such as PTFE, PFA and FEP. Each material has its strong point and proper selection of material should not always be made based upon cost. Electrical Properties, temperature rating and chemical compatibility should all be considered when choosing the proper size for your application. You should always try to select a tube that is in the middle of your shrink range. Selecting to high means that you have a lot of stress still built up in the material and selecting to low means that there is a possibility that the product might not shrink enough.

Polytetrafluoroethylene (PTFE) has the highest temperature rating of all the heat shrinkable tubing at a continuous 500°F. The biggest drawback is that the PTFE requires a minimum temperature of 625°F to begin the shrinking process. This includes the part that is being encapsulated. If the subsurface does not see the 625°F the PTFE will come in contact with the part but will not shrink completely. Lower temperature Fluoropolymers such as Fluorinated ethylene propylene (FEP) have a little lower temperature rating but shrink at a much lower and more controllable temperature. FEP has a continuous working temperature of 400°F but will start to shrink around 230°F which allows for encapsulation of sensitive glass or plastic parts. Both Fluoropolymers are chemically inert and may be used on all sorts of applications such as corrosive fluid handling and even medical applications such as coatings for catheters. PTFE tubing is known for its low coefficient of friction which makes it great for push-pull type applications that dominate the automotive industry.

High temperature wire splicing applications can benefit from an interesting match of PTFE and FEP tubing which when combined create a melt liner or adhesive liner. This meltable liner bonds to bare wires and creates an impenetrable water tight barrier between the elements and the splice.

When selecting a Heat Shrinkable PTFE tube for your application there are two other factors to consider, Shrink Ratio and Wall Thickness. PTFE Tubing can be developed in a extremely High Shrink ratio such as a 4:1, which is perfect for covering oddly shaped parts, or a standard 2:1 shrink ratio. Wall thicknesses are based off of the American Wire Gauge (AWG) and are set at Light Wall, Thin Wall and Standard Wall.
