Products Description
What is Tert-Butylphenyl diphenyl phosphate/BPDP?
Tert-Butylphenyl Diphenyl Phosphate, referred to as BPDP, is a colorless liquid with low volatility, insoluble in water, and good stability at room temperature. It belongs to the class of organic phosphate compounds and has good thermal stability and antioxidant properties. BPDP also has good solubility and optical properties, and is sometimes used as a coating and plastic additive.
BPDP is mainly used as a flame retardant to reduce the burning speed and smoke density of plastic products and polymer materials. It is widely used in electronic and electrical equipment, building materials, automotive parts, cables, aircraft parts and other fields, and can effectively reduce the risk of fire and fire spread.

Uses
- Flame retardant field: Tert-Butylphenyl Diphenyl Phosphate is a new generation of halogen-free organophosphorus flame retardant, which is widely used in flame retardant PVC, cellulose resin, synthetic rubber, phenolic resin, epoxy resin, polyester fiber and other materials.
- Plasticizing field: BPDP can be used as a plasticizer, which is compatible with a variety of plastic and rubber materials, can improve the flexibility and processing performance of the material, and improve the mechanical properties and electrical properties of the material.
- Lubrication field: BPDP has lubricating properties and can be used as a lubricant and release agent. It is used in machinery manufacturing, mold processing and other fields to reduce friction and wear.
- Other fields: BPDP can be used as an additive for gasoline and lubricating oil to improve the performance and stability of oil products and inhibit the oxidation and corrosion of oil products; it can also be used to prepare phosphate fire-resistant oils and fire-resistant hydraulic oils for mechanical equipment in the fields of electricity and machinery.
Safety Information
- Tert-Butylphenyl Diphenyl Phosphate has no obvious toxicity under normal conditions of use. As a chemical, it still needs to be treated properly.
- Wear appropriate personal protective equipment such as safety glasses, protective gloves and protective clothing when handling. Avoid direct contact with skin and eyes, and avoid inhaling its vapor. If ingested or inhaled, seek medical assistance immediately.
- BPDP should be kept away from fire and high temperature, and avoid contact with oxidants and strong acids to avoid dangerous reactions.
