Single wall heat shrink tube
This product is composed of cross-linked polyolefin. Polyolefin is a material with heat insulation and waterproof properties. It is produced in accordance with military standards. The main performance of the product is sealing and waterproofing.

What's special about Single wall heat shrink tube?
- heat insulation
- sealing and waterproofing
- very flexible
- Wall Thickness: Single-wall heat shrink tubing is thinner compared to dual-wall tubing and does not contain an adhesive inner layer.
- Operating Temperature: Usually ranges from -55°C to 125°C, depending on the material.
- Dielectric Strength: Provides excellent electrical insulation, making it ideal for wire and cable protection.
- Resistance Properties: Offers good resistance to abrasion, chemicals, and environmental factors.
