What is the difference between flame retardant and fireproof

Summer is hot and dry, which is a high incidence period of sudden fire. Whenever the fire loss is reported in the news, it is often accompanied by the cause of the fire. Among them, it is often mentioned that flammable and explosive materials ignited the fire.

Therefore, with the improvement of people's awareness of fire protection, people are more willing to buy products with flame retardant characteristics in production.

Flame retardant grade refers to the property of substance or material after treatment that significantly delays the spread of flame.

The flame retardant grade of plastics increases from Hb, V-2, V-1 to V-0:

HB: the lowest flame retardant grade in UL94 standard. For samples 3 to 13 mm thick, the combustion rate is required to be less than 40 mm per minute; For samples less than 3 mm thick, the combustion rate is less than 70 mm per minute; Or go out in front of the 100mm mark.

2. V-2: after two 10 second combustion tests on the sample, the flame goes out within 60 seconds. There can be combustibles falling.

3. V-1: after two 10 second combustion tests on the sample, the flame goes out within 60 seconds. No combustibles can fall.

4. V-0: after two 10 second combustion tests on the sample, the flame goes out within 30 seconds. No combustibles can fall. The flame retardant spiral protective sleeve produced by parlmu company is of V-0 level, which is suitable for fields with strict flame retardant requirements such as petroleum, electric power, coal mine and so on.

5. The spiral protective sleeve produced by parlmu company uses modified PP material, which not only inherits the good wear resistance of PP, but also combines the superior elasticity of PE. At the same time, it has the characteristics of corrosion resistance, high and low temperature resistance and aging resistance, which has been highly praised by our customers. Later, with the continuous expansion of application fields and the continuous refinement of application requirements, such as some mining industries, science and technology fields, etc. The application prospect of spiral protective sleeve will be better and better.
