When using a heat gun to recover shrink sleeving of any kind, it is important that your technique deliver gradually increasing and evenly distributed heat to the location where recovery is desired. Equally important in this recovery application is the coating (PEEK, Kapton®, and etc.) already surrounding an insulated conductive wire that the PEEK heat shrink is being applied over. Therefore there is a very fine line between achieving full recovery and melting the product. PEEK heat shrink recovery occurs at very near the same temperature. Ideal for shrinking on wire or round mandrels.Continuous service temperature: 500☏ (260☌). PEEK’s inherent purity and lubricity make it an excellent choice for applications such as wire coating on medical devices, electronics, wire & cable insulation splice aid, telecom hardware, and oil exploration equipment.Īs an alternative to traditional fluoropolymer protective coatings like Teflon® or Kapton® tape, it is ideally suited for challenging environments where abrasion, intense pressure, chemicals, water, or dielectric interference pose a threat to wires and electrical components. When shrunk onto components, it forms an impenetrable “second skin” that is impervious to contaminants, preserving the integrity and performance of whatever is inside. PEEK, a linear, semi-crystalline aromatic polymer, is considered the highest performing thermoplastic material due to its ability to withstand extreme temperatures, high pressure and caustic fluids.ĭaburn’s SH740 PEEK heat shrink tubing provides a “shrink to fit” layer of protection for sensitive or critical components.
