What are the requirements for the application of flame retardants in foam plastics? With the expansion of the application scope of rigid polyurethane foam, the performance of foam plastics has higher requirements, among which flame retardants are the main problem. Rigid polyurethane foam is widely used in refrigerators, refrigerators, refrigerators, refrigerators and other insulation materials. The basic defects of buildings, tanks and pipes are flammable. Now, together with the flame retardant manufacturers, what is the requirement for the application of flame retardants in foam plastics?

Halogen free flame retardant can meet the fire retardant requirements of all walks of life, such as the common insulation materials in daily life. External insulation is not only suitable for civil construction and industrial heating construction in cold areas, but also suitable for refrigeration and air conditioning construction in warm areas. It can be used in new projects and more suitable for energy-saving renovation projects of old buildings. The external thermal insulation materials require high technology content, complete data matching and advanced and reasonable construction technology. Promoting the construction of external insulation technology will stimulate the development of energy-saving materials in China's high-tech industries.

In order to make the flame-retardant base material meet the requirements of flame-retardant, a certain amount of flame retardant is usually added, but this often greatly deteriorates the physical mechanical properties, electrical properties and thermal stability of the material, and at the same time causes some problems in material processing technology. Therefore, people should according to the use environment and the use demand of the material, carry on the appropriate degree of flame retardant to the material, but can not ignore the actual situation, blindly require the material to have the high level of flame retardant.

In the 60 years since the early 1950s, especially in the 30 years since the early 1980s, flame retardant (FR) and flame retardant polymer materials have played an important role in reducing the loss of life and property caused by fire. At present, the total amount of FR in the world ranks second only to plasticizer in all kinds of plastic additives.
