Chengdu Focus Infra Materials Company is manufacturing various type of heat shrink tubes, which are widely used in various industries and applications, such as electrical insulation, cable bundling, and protection. They work by shrinking in size when heat is applied, creating a tight and secure fit around a wire or cable. While they perform this basic function, different types of heat shrink tubing differ in their materials, sizes, and properties.

  One common type of heat shrink tube is a polyolefin tube, which is made from a blend of polyethylene and polypropylene. Polyolefin tubes have good electrical insulating properties, are flame retardant, and are commonly used in electrical insulation for wire and cable harnesses.

  Another type of heat shrink tube is the fluoropolymer tube, which is made of materials such as Teflon, FEP, and PFA. Fluoropolymer tubes are highly resistant to high temperatures, chemicals, and UV exposure. This makes them ideal for use in high-temperature, harsh chemical environments, and military electronic systems.

  The third type of heat shrink tube is the silicone rubber tube, which is highly resistant to extreme temperatures and can sustain continuous operation at up to 200°C. Silicone tubes are commonly used in electronic systems, medical equipment, and automotive applications.
