Fire resistance rating of thermosetting polystyrene foam insulation board

 

Thermosetting polystyrene foam insulation board equipment in order to change the combustion essence of polystyrene insulation board thermoplastic, the use of special flame retardants for polystyrene particles flame retardant coating method, solved the problem of flame retardant and thermal insulation mutual constraints, and successfully made thermosetting polystyrene insulation board.

 The test results show that the combustion performance of the coated polystyrene board changes from thermoplastic to thermosetting, all the properties of the board meet the requirements of the standard, and the thermal conductivity and combustion performance are effectively improved. The fire rating shall reach A2.

Our company-Leili Chemical Co.,Limited specializes in the production of expanded polystyrene products, used in packaging, construction and other fields.
