PTFE Sleeve
PTFE sleeves are protective coverings made from Polytetrafluoroethylene (PTFE), a synthetic fluoropolymer with exceptional non-stick and high-temperature resistant properties. These sleeves are utilized to safeguard components, equipment, or wires in various industrial, electrical, and mechanical applications.
Due to PTFE’s excellent chemical resistance, it can shield materials from corrosive substances, making PTFE sleeves suitable for use in harsh chemical environments. Their remarkable temperature resistance allows them to withstand extreme heat and cold, making them applicable in both cryogenic and high-temperature settings.
PTFE sleeves are employed to insulate and protect wires and cables in situations where traditional materials may degrade or fail due to temperature variations, chemicals, or friction. They are also used as a non-stick layer in various manufacturing processes where materials might adhere to surfaces.
Overall, PTFE sleeves offer reliable insulation, durability, and protection, making them a valuable solution in numerous industries such as electronics, automotive, aerospace, and chemical processing, where robust shielding and resilience to harsh conditions are paramount.
The PTFE Sleeves manufactured by Integra are used for applications involving high temperatures, high frequencies,or both. Sleeving covered by this specification possesses excellent electrical properties, which remain practically constant over a wide ranges of frequency, temperature and humidity, and has a very low loss factor.
Although many wire-ended capacitors and resistors are used on tagboards without sleeving, this is not so when point-to-point wiring is necessary, as in, for example, a miniature I.F strip.In this and like instances, the use of sleeving on bare wire is generally a quick and effective wiring method. It should be borne in mind that there will be space between the sleeving and conductor which is not present with covered wire. Moisture may enter into this space and become trapped, causing subsequent corrosion of the conductor and a lowering of insulation resistance when the sleeved wires touch. In a similar manner large diameter sleeving, when used to hold together a number of covered wires, may form a dangerous moisture trap. In all cases sleevings should be chosen to be as tight a fit as possible on the conductor. use of a suitable lubricant is advised to facilitate insertion of the conductor.
