Intumescent Synergies Environment-Friendly Flame Retardant For Rigid PU Foam
TF-501 is a composite intumescent flame retardant, based on phosphorus-nitrogen synergies. It mainly developed for rigid PU foam, due to its gray appearance, TF-501 can't be used for the white foam.
Application: TF-PU501 is used solely in flameproof treatment for rigid polyurethane foam. UL-94 V-0 can be achieved when total loading of 9% is reached, and the total loading of 15% to achieve classification for the burning behavior of building materials and products GB / T 8624-2012 B2 level.
1 . Gray powder, expands when heated, efficient in smoke suppression.
2 . Excellent water resistance, not easy to precipitate, high flame retardant efficiency.
3 . Halogen-free and none heavy metal ions. pH value is neutral, safe, and stable during production and use, good compatibleness, not to react with other flame retardant and auxiliary.
