Heat Shrink Tubing


Description

Component Supply's offering of heat shrink tubing consists largely of PTFE and FEP products. However, polyolefin and pebax are also available.

Zeus PTFE (polytetrafluoroethylene) heat shrink standard wall tubing provides an effective technique for encapsulating and protecting wires, cables and other critical components exposed to volatile environments. Provided in an expanded state, this material can be shrunk through heat application to create tight, protective sleeve for material subjected to extremes of heat, corrosion, shock, moisture or other acute environmental conditions. PTFE possesses the lowest coefficient of friction making it ideal for applications needing lubricious material. It is chemically resistant to all common solvents, acids and bases, chemically inert and has a high dielectric strength over a broad temperature range. This tubing can be sterilized chemically and is autoclavable. The minimum shrink temperature for PTFE tubing is approximately 654°F to 670°F (346°C to 354°C). PTFE heat shrink tubing is available in 2:1 ratios for thin, standard and light wall options as well as a standard wall 4:1 ratio.

FEP possesses many of the same traits as PTFE heat shrink but is sometimes preferred over PTFE because of its lower shrink temperature (400 degrees) and its ability to be autovclaved and gamma sterilized. Compared to PFA, FEP offers greater flexibility, optical clarity and high lubricity. It is resistant to most chemicals except molten alkali metals, fluorine (gas) and some other halogen complexes. It also has excellent dielectric strength.

Polyolefin heat shrink tubing is extremely thin, soft, pliable and tough making it ideal for the demands of medical device design and manufacturing. This transparent tubing is known for its rapid recovery, low longitudinal shrinkage, high compressive strength and superior surface finish. It also acts as an effective moisture/vapor barrier.

Palladium Pebax was the first Pebax™ heat shrink tubing developed. It is a highly flexible, tough, durable and stable heat shrink tubing, which can be Gamma and E-Beam sterilized. It is known for its low longitudinal shrinkage, superior surface finish and high adhesion to material.


Application Examples

Applications for blunt needles occur in the following industries for dispensing applications involving tight and/or angled positions.
  • AEROSPACE: flouropolymers have a growing use in the aerospace industry, particularly in wire harness applications, seamless coverings to composite forming mandrels, fiber optic, hydraulic, wire coating and sealing solutions.
  • ELECTRICAL: PTFE shrink tubing is used for sleeving electrical connections in devices where the connections need to be protected from exposure to temperature extremes or where friction would be a concern.
  • MEDICAL: PTFE is prevalent in the medical field, particularly in its use in catheter shafts, catheter fusing, electrosurgical instruments, laparoscope instrument insulation.
  • FIBER OPTICS: PTFE shrink tubing is used in the fiber optics industry for sleeving and jacketing certain connections to protect them.

Stock and Customization

All heat shrink tubing comes in its expanded state. However, a brief application of heat allows the tubing to mold itself around intricate and irregular shapes to create a snug, seamless covering. Standard 4-foot lengths are available; however, our proprietary processes and equipment give us the expertise to produce customer-specific lengths precisely fitting the items needing coverage and making them as effective as possible in their application. Our cuts are straight, maintain the integrity of the tubing dimensions and hold tight tolerances. In certain sizes and situations our capabilities allow us to redraw this tubing to custom inside diameters, outside diameters and walls. Minimum quantities may apply depending on current stock. For more custom fabrication information, please contact a Component Supply representative who can inform you of the best options for your specific application.
