Butylated Triphenyl Phosphate Ester (BPDP), identified by CAS number 56803-37-3, is a prominent organophosphorus compound that has carved out a significant niche in the polymer additives market. Its unique chemical structure confers a combination of properties that make it highly effective as both a flame retardant and a plasticizer. Understanding these properties is key for researchers and manufacturers seeking to leverage its benefits. As a dedicated supplier of chemical flame retardants, we provide insights into BPDP's chemical profile and applications.

Chemical Structure and Properties of BPDP

BPDP is a phosphate ester, specifically a mixed ester of phosphoric acid. Its structure typically involves a triphenyl phosphate backbone where one phenyl group is substituted with a tert-butyl group. This molecular design imparts several key characteristics:

  • Formula: C22H23O4P
  • Molecular Weight: Approximately 382.39 g/mol
  • Appearance: Typically a clear, transparent, oily liquid at room temperature.
  • Phosphorus Content: Generally ranges from 8.5% to 9.5% by weight, which is crucial for its flame retardant activity.
  • Thermal Stability: BPDP exhibits good thermal stability, with minimal degradation at typical polymer processing temperatures. This ensures its effectiveness is maintained during manufacturing and in the final product.
  • Low Volatility: Its low vapor pressure means it is less likely to evaporate from the polymer matrix, providing durable flame retardancy and plasticization over time.
  • Compatibility: BPDP shows excellent compatibility with a wide array of polymers, including PVC, ABS, PC, PPO, and their alloys, as well as with other plasticizers and additives.

These properties make BPDP a versatile additive that can enhance the performance and safety of various materials. Many companies actively seek to buy BPDP due to its advantageous characteristics.

Key Applications of BPDP

The dual functionality of BPDP makes it suitable for a broad spectrum of applications:

  • Flame Retardant in Plastics: Primarily used in rigid and flexible PVC, ABS, PC/ABS alloys, PPO, and other engineering plastics to impart flame resistance, particularly in applications requiring compliance with standards like UL-94.
  • Plasticizer: In addition to flame retardancy, BPDP acts as an efficient plasticizer, improving the flexibility, processability, and impact strength of polymers.
  • Component in Intumescent Coatings: BPDP contributes to the char formation and stability of intumescent coatings, enhancing their fire-protective capabilities.
  • Flame Resistant Hydraulic Fluids: Its thermal stability and flame resistance make it suitable for use as a component in certain hydraulic fluid formulations.
