In extreme industrial environments like the petrochemical industry and automotive engine compartments, where heat and oil are common, the protective materials used for cables and connectors must be exceptionally durable. The key to Oil-Resistant Heat Shrink Tubing's use in these environments is that its specifications and performance precisely match the environmental requirements. Let's break it down.
1. Core Parameters
- Shrinkage-Related Parameters: No Deviation, Tight Wrap
Oil-Resistant Heat Shrink Tubing has an axial shrinkage rate of only 1%-10%. After heating and shrinking, it doesn't shrink too much towards the ends, preventing cable or connector damage and preventing poor contact. Furthermore, with a shrinkage ratio of 2:1, it can tightly wrap everything from thin sensor cables to thick hydraulic fittings, leaving no gaps.
- Temperature Resistance: High and Low Temperature Resistance
It can withstand temperatures as low as -55°C for 4 hours without cracking even when bent, making it suitable for outdoor equipment and cold chain sensor cables in northern winters. As for high temperatures, it shrinks stably at 175°C and maintains performance even after seven days of continuous use at 150°C. Even when subjected to heat shocks up to 225°C, it remains resistant to melting or cracking, making it ideal for protecting cables in engine compartments and near boilers.
2. Key Performance
- Mechanical Properties: Tension-Resistant and Durable
With a tensile strength exceeding 13.8 MPa, it can withstand a tensile force of 1.4 kg per square millimeter, making it resistant to breaking when cables are pulled. With an elongation at break of at least 300%, it can be stretched to three times its original length before breaking. It resists breaking even when wrapped around sharp joints or subjected to minor impact.
More importantly, after seven days of use at 150°C, its tensile strength remains above 10.3 MPa, and its elongation at break exceeds 200%, ensuring it remains brittle or weakened despite long-term use in high-temperature environments.
- Oil-Resistant and Corrosion-Resistant: Undamaged by Oil
Oil-Resistant Heat Shrink Tubing can withstand 16 hours of immersion in 135°C oil without corrosion or deformation, maintaining a seal. This protects cables in petrochemical and hydraulic systems from oil seepage and short circuits.
Furthermore, when exposed to copper connectors at 150°C for 7 days, the heat shrink tubing will not crack, and the copper rod will not turn black or develop pitting. Contact with copper will not corrode, preserving the connector's electrical conductivity and extending the life of the equipment.
