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

type : ТТ-175

 ТУ 22.21.29-073-97284872-2017

  • 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: transparent
  • Recommended for use in high temperatures up to 175 °C
  • Resistant to fuels and lubricants, most inorganic and organic acids, alcohols, solvents, gasoline and aviation kerosene
  • Possess a high resistance to abrasion and cuts
  • Resistant to UV rays and weather conditions
  • Visual inspection of joints after shrinkage
  • Ideal for use in the aerospace and military industry
  • High temperature shrinkage due to the composite structure of PTFE and stiffness compared to traditional heat shrink tubes
  • After full shrinkage, forms a strong reinforcing casing with a minimum wall thickness of the tube

High temperature heat shrink tubes TT-175 with shrink ratio 2:1 are made of special mix of PTFE. They are designed for protection of insulation of electrical connections. 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 formular PVDF. The tubes with similar qualitites are known as Kynar, Deray KY 175, Canusa CKN 175, Sumimoto K, Hellerman TK 20, Rehau PVDF and others. The tubes have a wide operating temperature range from -55°С up to +175°С. After shrinkage the tube creates a hard armoring structure, keeps transperancy 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 important part of constructions in aero-space, chemical and military industries. The 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
