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.
