When chemical resistance and high temperature resistance are necessary, our high temperature fluoropolymer heat shrink is the perfect solution. They protect cables, tubes and other objects. The products conform to both military and commercial standards, and in most cases exceed those standards. Fluoropolymers offer increased lubricity for easy sliding, and low moisture absorption for enhanced dimensional stability. Three materials are readily available: PTFE (Polytetrafluoroethylene), FEP (Fluorinated Ethylene Propylene) and PVDF (Polyvinylidene Fluoride, Tradename **Kynar®).
Polytetrafluoroethylene (PTFE) Heat Shrink Tubing
From $4.14 per foot
PTFE heat shrink tubing is available in 2:1 and 4:1 shrink ratios, and is widely used in military applications (MIL-I-23053/12) because of its high continuous use temperature (250°C), and outstanding chemical resistance.
PTFE heat shrink tubing is the most difficult of the three fluoropolymer materials to shrink due to its extremely high shrinking temperature (325-340°C). |
Fluorinated Ethylene-Propylene (FEP) Heat Shrink Tubing
From $2.55 per foot
FEP heat shrink tubing is a common alternative to PTFE, with similar electrical and friction properties and chemical resistance. FEP heat shrinkable tubing conforms to Mil-I-23053/11, and UL 94 (V0, VW-1), and is suitable for continuous use at temperatures up to 204°C. |

Polyvinylidene Fluoride (PVDF, Kynar®)
Heat Shrink Tubing
From $5.49 per 4 FT STICK
PVDF heat shrink tubing is used in applications where continuous operating temperatures are 150-175°C. It is used where outstanding abrasion and cut-through resistance are required. We carry two types of PVDF tubing, which conform to either MIL-DTL-23053/18 Class 2 or MIL-DTL-23053/8. |
PTFE/FEP Dual Wall Heat Shrink Tubing
From $2.26 per FT
Our PTFE heat shrink tubing is also available with a "dual-wall" construction. It is constructed with an outer layer of heat shrinkable PTFE and an inner layer of FEP. It is easy to apply, and is designed to provide a tight, moisture-proof bond over wires, cable, connectors, splices, terminal, etc. During application, the PTFE shrinks tightly over inserted parts, while the inner layer of FEP melts and flows to encapsulate parts and provides a tight moisture-proof seal. |
