Core Differences
Heat Shrink Tubing Shrink Method：Requires heat to shrink and conform to the object.
Cold Shrink Tubing Shrink Method：Uses an elastic mechanism to expand and fit without heat.
Heat Shrink Tubing Shrink Installation Process：Must be heated with a heat gun or oven.
Cold Shrink Tubing Shrink Installation Process：Simply slides over the object and is released to contract.
Heat Material Composition：Typically made from polyolefin or PVC、FEP and other thermoplastic materials.
Cold Material Composition：Generally made from silicone rubber or EPDM rubber.
Environmental Resistance：Good resistance to moisture and chemicals.
Environmental Resistance：Excellent resistance to moisture, UV, and ozone.
Application Scenarios
Heat Shrink Tubing
- Electrical Insulation: Commonly used for insulating electrical wires and connections.
- Mechanical Protection: Provides protection against abrasion, chemicals, and environmental exposure.
- Bundling Wires: Ideal for bundling multiple cables together to keep them organized.
- Repairing Cables: Used for repairing damaged wires and connectors by providing a secure seal.
- Heat-Sensitive Applications: Best suited for applications where heat can be applied safely.
Cold Shrink Tubing
- High Voltage Applications: Frequently used in high voltage cable termination and splicing, where heat cannot be applied.
- Outdoor Installations: Suitable for outdoor use as it is highly resistant to UV and weather conditions.
- Flexible Environments: Ideal for applications that require flexibility and resilience in extreme temperatures.
- Difficult Access Areas: Used in tight spaces or areas where heating tools cannot be effectively used.
- Sealing and Insulating: Provides excellent sealing properties, making it suitable for waterproofing.
