the differences are different material characteristics, different application fields and different performance requirements.

1. Different material characteristics: enterprise gas equipment can prevent the spread of fire to a certain extent, and can ignite when encountering a fire source, but the combustion speed is slow, and the combustion will stop after stopping the action of the fire source. Combustible materials are flammable, and can continue to burn or even spontaneously ignite after burning, which cannot stop the spread of fire. Refractory materials have certain resistance to the fire source, and it is difficult to ignite when encountering a fire source, even if ignited, it is difficult to burn.

2. Different application fields: enterprise gas equipment is mainly used in buildings, electronic instruments, industrial and mining enterprises and other fields, and is the raw material for fire prevention and isolation, coatings and plastics. Combustible materials are used in many fields, such as architecture, furniture, decoration, automobiles and so on. Refractory materials are mainly used in fire-retardant building materials, power equipment, transportation, aerospace and other fields.

3. Different performance requirements: enterprise gas equipment needs to reach a certain flame retardant level before it can be used, combustible materials should be avoided as far as possible near potential fire sources, and flame-retardant materials should have the performance of not burning at a certain temperature or for a short time.
