What is the B1 level flame retardant standard? What are the flame retardant standards for flame retardants?
In fact, B1 level has become history. B1 level is the term in GB8624-1997 “Method for Classification of Combustion Performance of Building Materials”. According to the testing standards of GB8624-1997 “Method for Classification of Combustion Performance of Building Materials”, building materials are divided into Class A (non-combustible materials), Class B1 (flammable materials), Class B2 (combustible materials), and Class B3 (flammable materials).
A professional manufacturer that produces and sells flame retardants, textile flame retardants, paper flame retardants, water-based coating flame retardants, and polyurethane flame retardants.
