High temperature PTFE (polytetrafluoroethylene) heat shrink tubes with shrink ratio 2:1

type : ТТ-150

  • Designed for insulation and corrosion protection of electrical connectors, harness assemblies, and piping in chemically aggressive media, high mechanical loads, and high temperatures
  • Shrink ratio: 2:1
  • Material: PTFE (polytetrafluoroethylene) -does not support combustion
  • Color: black
  • Recommended for use in high temperatures up to 150 °C

High-temperature heat shrink tubes TT-150 with shrink ratio 2:1 are made of a special mix of PTFE. They are designed for the protection of the insulation of electrical connections. The perfect combination of qualities: mechanically and dielectrically stable, flame retardant, resistant to extreme temperatures and chemicals. The tubes are resistant to abrasion, cuttings, and other mechanical stresses. Special molecular formula PVDF. The tubes with similar qualities are known as Kynar, Deray KY 150, and others. The tubes have a wide operating temperature range from -55°С up to +150°С. After shrinkage, the tube creates a hard armoring structure, keeps transparency that lets the user control the quality of electrical connection. Ideal for long-term anti-vandal protection of marking tags installed on cables that are used in harsh environments. They are recommended to be used together with FR cables that are an important part of structures in aerospace, chemical, and military industries. The black tubes are supplied in cuts of 1.22 m (10 pcs in one pack). The sizes range is from 2.4/1.2 to 12.7/6.5 mm
