Product Info

Choose the optimal wire insulation for your factory—compare Heat Shrink Tubes and Silicone Glass Tubes to ensure electrical safety and performance in high-temperature environments.

When operating in high-heat or high-voltage industrial environments, selecting the right insulation tubing is critical for long-term safety, durability, and maintenance efficiency. This article compares the properties and advantages of ・Heat Shrink Tubes・ (ท่อหดด้วยความร้อน) and ・Silicone Glass Tubes・ (ท่อซิลิโคนเคลือบไฟเบอร์กลาส), guiding engineers and procurement teams to make informed decisions.

1. Key Features of Heat Shrink Tubes
・ Material: Polyolefin, fluoropolymer, or PVC
・ Operating Temp: -55℃ to 125℃ (some types up to 200℃)
・ Shrink Ratios: 2:1, 3:1, 4:1
・ Resistant to oil and chemicals (varies by material)
・ Meets IEC/UL insulation standards
Best for: Electrical panels, wire splicing, component protection

2. Key Features of Silicone Glass Tubes
・ Material: Fiberglass coated with silicone
・ Temp Resistance: 200℃ continuous, 250℃ peak
・ Flame retardant (self-extinguishing)
・ Maintains flexibility at high temperatures
・ Strong abrasion and mechanical resistance
Best for: Motors, ovens, transformers, steel furnaces

3. Heat Shrink vs. Silicone Glass: Key Differences
・ Temperature Resistance: Silicone Glass Tubes perform better in extreme heat
・ Flexibility: Silicone Glass remains pliable even at high temperatures
・ Tight Fit: Heat Shrink Tubes offer a snug, sealed fit after heating
・ Flame Resistance: Silicone Glass meets UL flame-retardant standards
・ Abrasion Resistance: Silicone Glass has superior durability in rough environments

4. Application Guidelines
・ High heat + vibration → Use ・Silicone Glass Tube・
・ Easy, secure fit → Use ・Heat Shrink Tube・
・ High voltage insulation → Both are suitable with proper standards
・ Abrasion-prone environments → Use ・Silicone Glass Tube・
