Flame retardant heat shrink tube as a more common type of protective material, its main use is to leave the fire source, itself in a certain period of time to extinguish. Many people have a certain misunderstanding of flame retardant heat shrink tubing, not that the product itself has the characteristics of non-combustible, but refers to a certain degree to stop the spread of flame. Flame retardant heat shrink tube is flame retardant grade is VW-1, oxygen index is 28, the meaning is able to leave the flame within 30S time itself extinguished, so as to achieve the purpose of flame retardant. Heat shrink tube material is divided into two kinds of flame retardant and non-flame retardant, flame retardant heat shrink tube that is added in the production of ingredients to achieve the effect of flame retardant.
How to distinguish the flame retardant heat shrink tube
Heat shrink tube model specifications are more, how to distinguish whether the heat shrink tube flame retardant easily identified by the following methods.
1, in most cases, black heat-shrinkable tube flame retardant than the color to be more excellent.
2, the name of the front with the word "semi-rigid" is non-flame-retardant (the method applies to the thick-walled heat shrinkable tube).
3、Judging whether the flame retardant by appearance, PE material heat shrinkable tube surface is bright is non-flame retardant, matte is flame retardant (this method is only applicable to PE material).
4, the working temperature ≥ 150 ℃ high-temperature heat shrinkable tube is generally flame retardant heat shrinkable tube, and belongs to the high flame retardant.
The features of Flame retardant heat shrinkable tube 
1, flame retardant heat shrinkable tube is prepared by using the international advanced level, the domestic leading high-tech, non-polluting environmental protection of new materials.
2, flame retardant heat shrinkable tube has the characteristics of low smoke, halogen-free, heavy metal-free, non-toxic, harmless, non-melt, non-drip, non-delayed combustion, has very good flame retardant performance, will not cause secondary harm to human body, in line with the EU RoHs standard.
3, flame retardant heat shrinkable tube in the protection of products, can do both fireproof layer, insulation layer, can also do the inner sheath, simplify the production process, set after heating shrinkage can be;.
4, flame retardant heat shrinkable tube itself has excellent mechanical properties, high temperature resistance, anti-aging, stable electrical insulation properties.
