Also, higher shrink ratios will require higher shrink temperatures.

If the tubing begins to crack, chances are you overheated the material.

When using a mandrel to shrink the tubing, it is important to pre-heat the mandrel to assure even and uniform shrinkage.

This transition from crystalline to amorphous must take place, since shrinkage will only occur during recovery from the gel state (re-crystallizing).

It is imperative that the tubing be heated uniformly until it becomes clear (gel state).

Always assure good ventilation in the immediate work area prior to beginning the heat shrink process.

The most reliable method for shrinking PTFE is the use of a controlled temperature oven however this is impractical with large harnesses or temperature sensitive components. You can use a heat gun or welding torch to shrink TFE, but these methods have a tendency to cause the material to overheat in small areas, while under-heating other areas, causing uneven shrinking and potential burning of the material. PTFE heat shrink tubing is the most difficult of the three fluoropolymer materials to shrink due to its extremely high shrinking temperature (325-340☌). PTFE heat shrink tubing is available in 2:1 and 4:1 shrink ratios, and is widely used in military applications (AMS-DTL-23053/12), industrial, biomedical, chemical and analytical sciences because of its high continuous use temperature (250☌), and outstanding chemical resistance.

Tested by SAE for Aerospace Material Specifications.

MIL-STD-2073-1: DOD material procedure for development and application of packaging requirements.

Biocompatible, TFE is certified FDA and USP Class VI for use in diagnostic, medical, and analytical applications consisting of heat shrink tubing.

Outstanding resistance to almost any chemical known (exceptions: alkali metals in molten state, fluorine gas at high temperatures, chlorine trifluoride).

PTFE 4:1 - Technical Specifications, click here Clear heat shrink tubing allows for a visual inspection of the completed installation.PTFE 2:1 - Technical Specifications, click here Dual Wall PTFE We offer a great variety of sizes (3/32” to 1”) and colors (black, red, white, blue, clear). Wirefy assorted heat shrink tubing comes organized in preconfigured kits to keep things neat and tidy. This industrial grade heat shrinkable tubing is UL listed and is compliant with all relevant electrical standards such as: SGS, RoHS, Reach, and ISO9001. This wire heat shrink tubing is flame retardant. Dual wall tubing design has the increased ability to stand up to wear and tear. Electrical Heat Shrink Tubing with Dual Wall Designĭual wall marine grade heat shrink tubing provides better rigidity and abrasion resistance. For best results we recommend using a heat gun. When adhesive flows, it pushes the air out and fills any gaps between the wire and the tubing, which makes the connection waterproof. Heat activated glue strongly adheres to wires, terminals or any other surfaces. A small fillet of clear adhesive (about 1 mm wide) becomes visible at the end of the heated tubing. When heat is applied, shrink tubing recovers and the internal adhesive layer melts.

This is a waterproof shrink tubing with the internal adhesive layer. Additionally, 3:1 marine heat-shrink tubing shrinks around wires and terminals more tightly, eliminating any air gaps.īest Heat Shrink Tubing Comes with Adhesive Lining Therefore, 3:1 shrink ratio tubing can be used in significantly more applications compared to 2:1 shrink ratio tubing. Its high recovery ratio makes it possible to repair most damaged cable jackets without removing connectors. When heat is applied, this wire shrink wrap tubing will recover to a 1/3 of its original diameter. Protecting surfaces against abrasion, peeling, and denting.Creating thermal insulation for heat sensitive components.Grouping loose wires (usually in wire harnesses).Identifying wires and cables (color-coding).Environmental seal to protect from moisture, UV, fuel and chemicals.Electrical insulation (wire repairs, insulating electrical terminals wires, protecting charging cables, insulating solder joints).It can be used in a variety of applications such as:
