Different applications require different materials, Dicore (www.dicoretubing.com) could provide most of material as below:

  • PTFE (fluoropolymer) tubes have the widest operating temperature range (−270 to 260 °C), low coefficient of friction, and high resistance to chemicals (almost everything except molten alkali metals, fluorine gas, and chlorine trifluoride). They however have very high shrink temperature (325–340 °C, or 250 °C). The tube has to be heated uniformly until it becomes clear, a sign of the polymer changing from crystalline to amorphous; on the transition back to crystalline the tube shrinks. 1.5:1, 2:1 and 4:1 shrink ratios are available on the market.
  • Viton, another fluoropolymer with high chemical resistance. Highly flexible. Shrink temperature is 120 °C.
  • Polyvinylidene fluoride (PVDF) tubes are intended for high temperature applications; −55 °C up to 150 °C (flexible PVDF) or up to 175 °C (semi-rigid Kynar). Their coefficient of friction is second only to PTFE. The material is resistant to abrasion, cut-through, ultraviolet and gamma radiation, and is up to 3 times as strong as standard polyolefin. The tubes are rated for use in plenum spaces. Common shrink ratio is 2:1, and shrink temperature ranges around 170 °C.
  • Fluorinated ethylene propylene (FEP) is a lower-cost alternative to PTFE. Its operating temperature range is up to 204 °C and the shrink temperature is as low as 190 °C. It has high chemical resistance, lower gas permeability and higher translucence than PTFE, excellent transmission of ultraviolet rays, and excellent electrical insulation. The shrink ratios are 3:1 and 6:1.
  • Neoprene (chlorinated elastomer) tubes maintain high flexibility even at low temperatures. The operating temperature range is −75 to 120 °C. The material is resistant to fluids and solvents and has good resistance to abrasion. The shrink temperature is 135 °C. Neoprene tubes are used as insulation, abrasion protection, and strain relief in military and aerospace. Common shrink ratio is 2:1.
  • Silicone rubber offers excellent resistance to scrape abrasion and high flexibility. The shrink temperature is 200 °C.
  • Polyolefin tubes, the most common kind, have maximum continuous use temperature from −55 to 135 °C, with shrink temperature of 90 to 130 °C. They are manufactured in a wide range of colors (including clear), and can be used for color-coding of wires in addition to other applications. With exception of black, they tend to have lower resistance to ultraviolet light; only black is suggested for outdoor applications. Common shrink ratio is 2:1; ratios 3:1, 4:1, and 6:1 are also available; higher ratios typically need higher shrink temperature. A version exists with shrink temperature as low as 80 °C, and operating temperature range −55 to 125 °C. Flexible and semirigid versions exist.
  • PVC tubes have operating temperature from −55 to 105 °C and shrink temperature 100 °C. They come in a range of colors, including clear (which is more transparent than clear polyolefin). They are higher-gloss, more scratch-resistant, tougher and stiffer than polyolefins. They are more resistant to degradation by ultraviolet light, all colors can be used outdoors.

Other special materials exist, offering qualities such as resistance to diesel and aviation fuels, or woven fabric for increased abrasion resistance in harsh environments.
