product advantages
1. Highly Effective Flame Retardancy
• P-Cl Synergistic Effect: The TCPP molecule contains both phosphorus (P) and chlorine (Cl), creating a powerful synergistic effect. The phosphorus promotes char formation (condensed phase mechanism), while both elements release radicals that quench the combustion process in the gas phase, making it extremely efficient.
• Primary Gas-Phase Action: This mechanism is particularly effective in preventing the flame propagation of materials like polyurethane foam.
2. Excellent Cost-Performance Ratio
• TCPP offers one of the best balances of high performance and low cost among halogenated phosphate ester flame retardants, making it a primary choice for many applications.
3. Good Compatibility and Plasticizing Effect
• It exhibits strong compatibility with various polymer matrices (especially polyurethane and epoxy resins), minimizing exudation.
• As a liquid, it acts as a processing aid and plasticizer, enhancing mixability and flow during manufacturing without severely compromising the physical properties of the final product.
4. Liquid Form and Ease of Processing
• Its liquid state at room temperature allows for easy pumping, precise metering, and thorough mixing, which is critical in processes like polyurethane foaming.
5. Relatively Good Hydrolytic Stability
• It possesses better resistance to hydrolysis compared to some other halogenated phosphates, ensuring long-term stability in the final product, even in humid environments.
product applications
1. Flame Retardant for Polyurethane Foam (Primary Application)
• Rigid Polyurethane (PIR) & Polyisocyanurate Foam: This is the largest and most critical application for TCPP. It is essential for achieving required fire safety ratings (e.g., B1/B2) in building and construction insulation boards, panels for roofs and walls, and refrigeration systems.
• Flexible Polyurethane Foam: Used in furniture, automotive seating, and mattresses where flame retardancy standards must be met.
2. Engineering Plastics & Polymers
• Epoxy Resins: Extensively used in epoxy potting compounds, encapsulation materials, and printed circuit boards (CCL) for electronic and electrical applications to achieve UL94 V-0 rating.
• PVC (Polyvinyl Chloride): Employed as a flame-retardant plasticizer in flooring, wall coverings, and wire & cable coatings.
• Coatings, Adhesives, and Sealants: Provides flame retardancy to various industrial coatings, adhesives, and sealants.
