Product Overview
BPDP (Tert-Butyl Phenyl Diphenyl Phosphate) is a colorless, transparent liquid with excellent thermal stability and halogen-free flame retardancy, specifically formulated for PVC applications. As an aromatic phosphate ester, it combines flame retardant properties with plasticizing effects, eliminating the need for additional plasticizers in many formulations. Its low volatility (vapor pressure <0.01 mmHg @ 25°C) and high compatibility with PVC resins ensure long-term performance in products like cables, pipes, and films, with no migration or blooming even after 5 years of service. Unlike halogenated flame retardants, it produces low smoke and non-toxic combustion products, making it suitable for indoor and sensitive applications.
Product Specifications
Scope of Application
Cable Jackets: Enhances fire resistance and electrical insulation in power cables (PVC-insulated), meeting IEC 60332-1-2 for vertical flame spread and maintaining dielectric strength >10 kV/mm.
Connectors: Ensures flame safety in high-temperature automotive wiring (105°C rating), passing SAE J2263 flammability tests for underhood applications.
Construction & Building Materials
PVC Pipes: Improves flame retardancy for underground and drainage systems, achieving DIN 4102 B1 classification (slow-burning) and resisting combustion during building fires.
Window Profiles: Provides weather resistance and thermal stability in outdoor applications, maintaining flame retardancy after 1,000 hours of UV exposure (QUV test).
Consumer Goods
Footwear: Used in PVC soles to meet flame resistance standards (ISO 9185) for work boots, preventing melt-drip and reducing burn injuries in workplace accidents.
Inflatable Products: Prevents premature degradation in pool liners and air mattresses, maintaining flexibility and flame retardancy during prolonged outdoor use.
Packaging
Food-Grade Films: Maintains product integrity while meeting flame retardant requirements for packaging machinery components, complying with FDA and EU 10/2011 food contact regulations.
Medical Packaging: Ensures sterility and safety in PVC-based medical device trays, with low extractables and compatibility with ethylene oxide sterilization.
