- Features:Low Specific Gravity, Reduced Water Sensitivity, Good Thermal Stability
Melagard P37 is a highly efficient, halogen-free intumescent flame retardant system used in polyolefins (PP, PE, EVA) and various rubber systems. Unlike Ammonium Polyphosphate-based systems, Melagard P37 is composed of phosphorus and nitrogen in an optimized ratio within a single molecule. It provides high flame retardancy, reduced smoke emissions, and lower release of toxic or corrosive gases. Other benefits include low specific gravity, low water sensitivity, high thermal stability, and ease of dispersion in polymer matrices. It was previously introduced as "EXP PP/37".
