SBRS-(4X)GRH
High-Shrink-Ratio, High Temperature Resistant, Adhesive-Lined ,Polyolefin Heat Shrink Tubing
It consists of a double layer of cross-linked polyolefin and polyamide PA. The product has high shrinkage and wear resistance characteristics, and is widely used in high temperatureenvironments such as wiring harnesses inside automotive engine compartments, electrical connections to electronic equipment, and other occasions where sealing is required.
Technical Data
It consists of a double layer of cross-linked polyolefin and polyamide PA. The product has high shrinkage and wear resistance characteristics, and is widely used in electronic equipment wiring connections, automotive harnesses, home appliance harnesses, wire and cable branches, metal pipelines, wire and cable repairs, and other occasions that require sealing.
Features
- 4:1 shrink ratio allows for fewer sizes to cover numerous splice configurations and diameters
- Hot melt adhesive made of polyamide (PA) material with high temperature resistance (no dripping at 125℃), strong permeability, and strong sealing performance
- Thick adhesive liner forms an effective barrier against fluids and moisture penetration
- Minimum shrink temperature: 70°C
- Continuous operating temperature: -45°C to 125°C
- Fully shrink temperature: 125℃
- Standard color: black, clear (other colors can be customized)
