Product Info

Heat shrink tubing is an affordable, effective solution for protecting electrical systems. It improves insulation, prevents leakage, and strengthens wiring in industrial and outdoor environments. This guide explains key materials, functions, and how to choose the right tubing for each application.

1. What is Heat Shrink Tubing?
Heat shrink tubing is a plastic sleeve that contracts when heated, forming a tight seal around wires or joints. It enhances electrical insulation, prevents moisture ingress, and improves durability—essential for high-voltage systems and harsh industrial environments.

2. Materials and Their Industrial Applications
・Polyolefin (โพลีโอเลฟิน): Excellent flexibility and heat resistance, ideal for general electrical use.
・PTFE (พีทีเอฟอี): Chemically inert and heat-tolerant, used in medical and aerospace settings.
・Elastomer (อีลาสโตเมอร์): Vibration-resistant and durable, suited for machinery with moving parts.

Each type is tailored to specific use cases. Always match material properties to operational needs.

3. Protective Mechanisms

・Electrical Insulation: Shields against short circuits and voltage leaks.
・Mechanical Protection: Prevents abrasion and strain-related damage.
・Water & Dust Sealing: Adhesive-lined types ensure moisture resistance and environmental protection.

4. Application Environment & Selection Factors
Key factors for choosing heat shrink tubing include:
・Operating Temperatures: Typical range is 80–200°C
・Chemical Exposure: Oil, solvents, and acids require chemical-resistant tubing
・Outdoor Use: UV-resistant types prevent degradation from sunlight
・Mechanical Load: Use reinforced or thick-walled tubing for high-stress areas

5. Selection Guidelines
・Size Before Shrinking: Should be slightly larger than the wire diameter
・Shrink Ratio: 2:1 for standard use; 3:1 for irregular shapes or connectors
・Adhesive Lining: Ensures waterproof seals
・Color Coding: Improves circuit identification and maintenance
