Zeus fluoropolymer heat shrink provides the ideal method for the application of a tight, protective jacketing to items subjected to extremes of heat, corrosion, shock, moisture, or other severe environmental conditions. Heat shrink protection extends the life of the covered components and helps sustain their performance. PTFE’s low coefficient of friction and chemical resistance have made it the polymer of choice for many of these applications.
PTFE is often regarded as the gold standard for polymer tubing because of its superior lubricity, temperature endurance, and chemical resistance. PTFE’s broad temperature tolerance makes it one of the few plastics that can be utilized in both high and low temperature applications.
PTFE heat shrink’s versatility and exceptional performance have resulted in its widespread use in applications ranging from medical devices to industrial, chemical, and analytical areas. PTFE’s high dielectric strength makes PTFE heat shrink well-suited for encapsulation of wires and electrical devices. For outdoor use, PTFE heat shrink is virtually impervious to weather.
Zeus PTFE heat shrink tubing is available in a variety of shrink ratios, including 2:1 and 4:1, and can be selected based on American Wire Gauge (AWG) or fractional sizes. We also provide custom specifications and tolerances, including our Sub-Lite-Wall™ sizes, upon request.
- APPLICATIONS
Encapsulation – PTFE heat shrink provides protection from a range of environmental extremes for your critical components. This heat shrink can easily tolerate wide temperature ranges, exposure to chemicals, and long-term weather exposure. PTFE heat shrink can be used to cover such items as temperature probes, metal roll covers, wires and cables, electronics, and sensors.
Insulation – PTFE heat shrink’s dielectric properties make it a good choice for encapsulating and insulating electrical components, including batteries (lithium and alkaline) and other electrical devices. PTFE heat shrink’s heat tolerance allows it to continue to perform in both high and low temperatures.
Wire Harness – PTFE heat shrink’s excellent dielectric properties make it a good choice for covering wires and cables, and it can even support splicing. Once covered, PTFE heat shrink also serves as insulation, and its properties are retained across its wide working temperature span.
- KEY PROPERTIES
Biocompatible – PTFE has a proven history of use within medical devices. For more information on PTFE’s biocompatibility, contact us today.
Broad Working Temperature – PTFE has an extended service temperature, allowing this heat shrink to operate in cryogenic temperatures up to 500 °F (260 °C).
Chemically Resistant – PTFE provides reliable protection from almost all common solvents, whether acids, bases, or hydrocarbons.
Easy To Clean – Because of the highly lubricious nature of PTFE, this material possesses a highly non-stick surface, making it easy to wipe clean.
Excellent Dielectric Strength – PTFE heat shrink has exceptional dielectric strength and thus doubles as insulation when used with electrical components.
Flame Resistant – The non-flammable nature of PTFE makes it a good choice for environments where there is high heat or the possibility of flame exposure.
Low Coefficient of Friction – PTFE has the lowest coefficient of friction of any polymer, making parts, cables, or wires covered with PTFE heat shrink easy to maneuver into confined spaces.
Low Extractables – The very low level of extractables for PTFE means that contaminants will not leach out of the heat shrink and into the parts it covers.
Mechanical Resistance – Once covered with PTFE heat shrink, the covered items have an increased mechanical resistance even under severe conditions; this is particularly beneficial for joined parts such as wire splices or other delicate connections.
Sterilizable – PTFE heat shrink’s temperature tolerance and physical properties allow it to easily tolerate ETO and autoclave sterilization protocols.
