DUWAI DR diesel resistant heat shrinkable tube
APPLICATIONS
The DR product is a widely used diesel resistant rubber heat shrinkable tubing. It is made of radiation cross-linked rubber elastomers, and is suitable for providing insulation protection for wires and cables in the environment of motor oils and lubricating oils.
OPERATING TEMPERATURE RANGE
- Continuous operating temperature: -75℃ ~ 150℃
- Minimum shrink temperature: 100℃
- Full recovery temperature: Above 150˚C
COLOR
Standard color: black, (Special sizes and cut pieces are available on request.)
- Shrink ratio: 2:1
- Excellent oil and chemical resistance
- Flame retardant
- Reliable abrasion resistance
Diesel elastomer heat shrink tubing is made of polymer elastomer radiation modification, can be used at high temperatures for a long time, and is resistant to diesel, aviation fuel, and high-temperature fluids. It can be used for the protection of military vehicles, high-speed trains, ship equipment or commercial cable terminals and separation joints.
Made of radiation cross-linked high-quality oil-resistant polymer, it is suitable for use in environments that require oil resistance and friction resistance. It has excellent oil resistance, chemical corrosion resistance and solvent resistance, and provides protection for wire harnesses, cables or covered components.
