1. Our flame retardant heat shrink tubing not only conforms to VW-1 flame retardant standards but also becomes self-extinguishing if caught on fire, thus significantly enhances the safety of your electric equipment.
2. This type of heat shrink tubing has very high insulating property, scratch resistance and anticorrosive qualities which make it the right product to use in the most adverse environments.
3.The flame retardant shrink tubing of ours shrinks well even in low temperatures, installation is very simple, and it can adapt to all sorts of cable protections.
Protection materials for cables are flame-retardant properties essential, not just as a fire safety aspect, but actually one of the key factors influencing procurement decisions for materials in areas like electronics, automotive wiring harnesses, and electricity systems. Under fire situations, common heat shrink tubes can become fuel, not just keeping the fire, but even contributing to spreading flames quicker. Thus, such failures might result in equipment degradation and/or system failure which could be accompanied by major safety hazards.
Towards this end, we have developed a flame retardant shrink wrap with a VW-1 flame-retardant rating that is characterized by a very high flame-retardant and self-extinguishing property, as well a the insulating and environmental protection features of the product. This type of flame retardant heat shrink tubing can greatly increase the performance of fire safety in cable system design while offering you a safe, durable, and reliable insulation protection solution.
Product Introduction:
Heat shrink tube, a kind of insulated protective sleeve, is made from polyolefin materials with some flame retardants added to provide heat-shrinkability. It offers great electrical insulation, high flexibility, minimal low-temperature shrinkage, and flame-retardant features at the same time. Complying with the VW-1 flame-retardant standard, this product is capable of greatly preventing flame propagation and even has the self-extinguishing feature when in contact with fire. Besides being able to offer sufficient insulation and mechanical protection for the electrical component, it significantly increases the level of fire protection for the system and is a great candidate for such high safety demands environments as electronic appliances, wires, electrical power, and telecommunications.

Advantages of Fire-Rated Heat Shrink Tubing:
1. Excellent Flame Retardant Performance, Enhancing Electrical Safety.
Flame resistant heat shrink tubing is constructed from a polyolefin base mixed with flame retardants, conforming with VW-1 fireproof regulations. It has a strong flame spread prevention capacity, and when subjected to fire, it extinguishes by itself, thus minimizing the dangers of fire resulting from short circuits and heating in the electrical lines, ensuring better safety shield for electronic gadgets and wiring harnesses.
2. Excellent Insulation and Environmental Protection Capabilities.
Heat shrinking causes the product to fit snugly over wires and contacts giving it a reliable electrical insulation, it protects against moisture, dust, and is resistant to abrasion. In addition to that it will also resist corrosion to some extent, hence prolonging the lifespan of electrical parts along with cables.
3. Wide Temperature Adaptability, Suitable for Harsh Working Conditions.
Fire rated heat shrink can operate stably for extended periods in environments ranging from -55℃ to +150℃, with a minimum shrinkage temperature of only 110℃ and a full shrinkage temperature of 200℃. Even in alternating high and low temperature environments or complex industrial environments, it maintains stable mechanical properties and protective effects.
4. Uniform Shrinkage and Easy Installation.
Our 1kV heat shrink tube has a 2:1 shrinkage ratio that enables uniform shrinking even in very little space as well an ability to shrink without breaking in cold temperatures. This unique material gives the user an easy bonding of the cables and components of even different specifications within a few minutes.
The ability for fast bonding with high installation efficiency is just what electronics industry, power, automotive industry and telecommunication equipment are looking for. These fields will benefit greatly from the application of this product which has very good properties and is versatile.
