Products Description
PE heat shrink tubing is a tubular insulation material with a shape memory function, modified by electron beam irradiation based on cross-linked polyethylene (XLPE), which complies with UL 224. The standard shrinkage ratio is 2:1 to 4:1, and the operating temperature range is -55°C to 125°C (UL heat aging test passed).

- Question: What are the shrink ratios of the heat-shrinkable sleeves?
Answer: We offer 2:1, 3:1 and 4:1. The 2:1 (customizable) has a high fitting degree and a small change in size. The 4:1 has a wide range of adaptability and is suitable for different objects.
- Question: What is the shrink temperature range of the heat-shrinkable sleeves?
Answer: It's between 80 - 120°C (It varies for different materials and can be customized). Within this range, the heat-shrinkable sleeves will shrink evenly and quickly. Common heating equipment can be used and there will be no charring or deformation.
- Question: What are the maximum and minimum working temperatures of the heat-shrinkable sleeves?
Answer: The maximum is approximately 105°C. Under high temperatures, it has good mechanical and insulation properties. The minimum is - 55°C. It won't become brittle in cold environments and can be used for protection in outdoor settings, automotive wire harnesses and so on.
- Question: What are the standard inner diameters and wall thicknesses of the heat-shrinkable sleeves?
Answer: There are various inner diameters, such as 3mm, 6mm, 10mm, etc. The wall thicknesses include 0.5mm, 1mm, 1.5mm (customizable), etc. Thin walls are used in compact spaces, while thick walls are used in high-voltage or scenarios that require high mechanical strength.
