Flame retardant heat shrink tube

    Flame-retardant heat shrinkable tube is a 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 misunderstandings about flame-retardant heat shrink tubing. It does not mean that the product itself is non-combustible, but that it can prevent the spread of flames to a certain extent. The flame retardant heat shrinkable tube has a flame retardant grade of VW-1 and an oxygen index of 28. Its significance is that it can extinguish itself within 30 seconds of leaving the flame, thereby achieving the purpose of flame retardancy. Heat shrinkable tube materials are divided into two types: flame retardant and non-flame retardant. Flame retardant heat shrinkable tubes add flame retardants during the production and ingredients process to achieve flame retardant effects.

    Flame-retardant heat shrinkable tubes are made of environmentally friendly PE polyethylene materials. Environmentally friendly heat shrinkable tubes do not produce toxic gases and harmful substances when burned. They have many advantages such as flame retardant, insulation, environmental protection, and stable performance.

Distinguish flame retardant heat shrink tubing

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

1. In most cases, the flame retardancy of black heat shrinkable tubes is better than that of colored heat shrinkable tubes;

2. Those with the word "semi-hard" in front of the name are non-flame retardant (this method is suitable for medium-thick wall heat shrinkable tubes);

3. Determine whether it is flame retardant by its appearance. The bright surface of the heat shrinkable tube made of PE material is non-flame retardant, and the matte surface is flame retardant (this method is only applicable to PE material);

4. High-temperature heat-shrinkable tubes with working temperatures ≥150°C are generally flame-retardant heat-shrinkable tubes and are highly flame-retardant.

Features of flame retardant heat shrink tubing

1. Flame-retardant heat shrinkable tubes are made of internationally advanced, domestically leading high-tech, pollution-free and environmentally friendly new materials;

2. Flame-retardant heat shrink tubing has the characteristics of low smoke, halogen-free, heavy metal-free, non-toxic, harmless, no melting, no dripping, no flame delay. It has very good flame retardant properties and will not cause harmful effects on the human body. No damage, complies with EU RoHs standards;

3. When protecting products, flame-retardant heat shrinkable tubes can be used as fireproof layers, insulation layers, or inner sheaths, which simplifies the production process and can be heated and shrunk after being put on;

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

Flame retardant heat shrink tubing uses

1. Flame-retardant heat shrinkable tubes are mainly used in the production of insulation for wires and cables, as well as outer protection of electronic components. Wires, cables, and electronic components (resistors, capacitors, inductors) protected by flame-retardant heat shrink tubes can ensure the smooth flow of power and communication cables in the event of a fire. That is, there will be no short circuit under the conditions of loading 600V voltage and 125℃, thus ensuring the smooth flow of the line, and no toxic gas will be produced during combustion, maximizing time gain for the rescue of human life and property.

2. Flame-retardant heat shrinkable tubes can also be used to protect power and communication lines and pipelines. When a fire occurs, they can prevent the spread of fire and prevent damage to power and communication lines. Its excellent wear resistance can also protect the product well and extend its service life.
