Flame retardant heat shrink tube

Release date:2020-10-07 author:admin Click:

Flame retardant heat shrink tube is a relatively common type of protective material. Its main purpose is to leave the fire source and extinguish itself within a certain period of time. Many people have a certain misunderstanding about flame retardant heat shrink tube. It does not mean that the product itself is non-flammable, but that it can prevent the spread of flame. Flame retardant heat shrink tube has a flame-retardant grade of VW-1, it can extinguish itself within 30 seconds of leaving the flame, so as to achieve the purpose of flame-retardant. The material of heat shrink tube is divided into two types of flame-retardant and non-flame retardant. Flame retardant heat shrink tube is a flame retardant added in the production batching process to achieve the flame retardant effect.

 

Next we will specifically introduce how to distinguish flame retardant heat shrink tube and its characteristics and uses.

 

How to distinguish flame retardant heat shrink tube

There are many types and specifications of heat shrink tube. How to distinguish whether the tube is flame retardant can be easily identified by the following methods.

1. In most cases, the flame retardancy of black heat shrink tube is better than that of color;

2. Judge whether it is flame-retardant by appearance. The bright surface of PE heat shrink tube is non-flame retardant, and the matte surface is flame-retardant (this method is only applicable to PE materials);

3. High-temperature heat shrink tube with working temperature ≥150℃ are generally flame-retardant heat shrink tube.

 

Characteristics of flame retardant heat shrink tube

1. Flame retardant heat shrink tube is made of international advanced level, domestic leading high-tech, pollution-free new environmental protection materials;

2. Flame retardant heat shrink tube has the characteristics of low smoke, no halogen, no heavy metal, non-toxic, harmless, non-melting, non-drip, non-flammable, and has good flame-retardant properties, which will not cause damage to the human body, in line with RoHs standards;

3. When the flame retardant heat shrink tube is used as a protective product, in addition to as a fireproof and insulating layer, also an inner sheath, which simplifies the production process. After being covered, it can be heated and contracted;

4. Flame retardant heat shrink tube itself has excellent mechanical properties, high temperature resistance, anti-aging, and stable electrical insulation properties.

 

Third, the use of flame retardant heat shrink tube

1. Flame retardant heat shrink tube is mainly used for the insulation of wires and cables, the outer protection of electronic components. Wires, cables and electronic components protected by flame retardant heat shrink tube can ensure the smooth flow of power and communication cables in the event of a fire. That is, there is no short circuit under the condition of 600V voltage and 125°C, thus ensuring the smooth flow of the line, and the combustion does not produce toxic gas, which saves the lives and properties of personnel and maximizes time.

2. Flame retardant heat shrink tube can also be used as the protection of power and communication lines. When the fire occurs, it can prevent the fire from spreading and prevent damage to the power and communication lines. Its excellent wear resistance can also protect the product well and increase the service life.
