TF-PU501
Model No.: TF-PU501
產品簡介
TF-PU501 is solid composite halogen-free phosphorus-nitrogen containing intumescent flame retardant, it acts both in the condensed phase and the gas phase.
產品特點
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.
產品用途
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 total loading of 15% to achieve classification for burning behavior of building materials and products GB / T 8624-2012 B2 level.
