Heat-Shrinkable Silicone Rubber Tubing

Product Description

Heat-Shrinkable Silicone Rubber Tubing is made from high-quality silicone rubber, offering excellent resistance to high temperatures, arc, and corona. When heated, the silicone heat shrink tubing tightly conforms to the protected object, forming a solid insulating layer that ensures reliable electrical protection. Soft, flexible, and easy to install, it is ideal for insulating electrical appliances, lamps, electronic instruments, and other equipment. Non-toxic and odorless, it meets environmental protection requirements, making it widely used in electric power, chemical, and medical industries to ensure safe and stable equipment operation.

Shrink Ratios Available: 1.7:1 & 2:1

Product Features

• High-Temperature Resistance
  Because silicone rubber can withstand temperatures from -50°C to +200°C, the tubing provides reliable insulation and protection in extreme environments.

• Excellent Chemical Resistance
  Because of silicone’s chemical stability, silicone heat shrink tubing resists acids, alkalis, solvents, and other harsh substances, maintaining performance even in challenging chemical environments.

• Superior Electrical Insulation
  Because of its dielectric properties, the tubing offers excellent electrical insulation, helping prevent electrical faults and ensuring the safe operation of wires and equipment.

• Waterproof Performance
  Because silicone is naturally hydrophobic, it protects wires and connectors from moisture, humidity, and other environmental hazards.

• High Elasticity & Flexibility
  Because of its elastic silicone material, the tubing adapts to objects of various shapes—circular or irregular—making installation simple and versatile.

• Ease of Installation
  Because silicone heat shrink tubing shrinks rapidly when heated, it can tightly encapsulate objects using a heat gun or other heat source, saving time and effort on site.

• Durability & Long Service Life
  Because silicone is resistant to aging and mechanical damage, the tubing maintains its protective properties over many years.

• Customizable Sizes & Colors
  Because it is available in various sizes and colors, the tubing can be adapted to different project requirements.

FAQ:

How does silicone heat shrink tubing work?

Silicone heat shrink tubing is made of materials such as silicone and polyolefin, and has good elasticity and plasticity. When heated by a heat source, the internal materials will flow and uniformly adhere to the protected object. As the temperature increases, the silicone heat shrink tube will shrink and tightly wrap around the protected object, playing a protective and sealing role.

How to use silicone heat shrink tubing?

When using silicone heat shrink tubing, first place the protected object inside the tubing, and then use a heat source (such as a hot air gun or oven) to heat the tubing, causing it to shrink and tightly wrap around the protected object.

Can silicone heat shrink tubing be used for high-temperature applications?

Yes, silicone heat shrink tubing has good high-temperature resistance and can be used in high-temperature environments.

What is the difference between silicone heat shrink tubing and other types of tubing?

Compared with other types of pipes, silicone heat shrinkable pipes have better heat resistance, electrical insulation, chemical stability, aging resistance and other advantages, and are more convenient to operate.

What safety precautions should be taken when using silicone heat shrink tubing?

When using silicone heat shrink tubing, safety precautions should be taken, such as avoiding use in flammable and explosive environments and preventing burns.

How long does it take for silicone heat shrink tubing to fully shrink?

The time required for complete shrinkage of silicone heat shrink tubing depends on factors such as its specifications, material, and heat source. Generally, it takes several seconds to minutes to fully shrink.

Can silicone heat shrink tubing be used for insulation and protection?

Yes, silicone heat shrink tubing has good insulation and protective properties, and can be used for insulation protection of wires and cables, as well as sealing and protecting various components such as pipes, joints, valves, etc.
