Tricresyl Phosphate (TCP)

Tricresyl Phosphate (TCP) is a widely used aryl phosphate ester known for its excellent flame-retardant properties, high plasticizing efficiency, good thermal stability, low volatility, and superior hydrolytic stability. It is primarily employed as a plasticizer and flame-retardant additive in PVC, cellulosic polymers, synthetic rubber, and engineering resins.

Frequently Asked Questions (FAQs)

Q: What is the difference between TCP, TOCP, and TxCP?

A: TOCP refers specifically to tri-o-cresyl phosphate (pure ortho-isomer), which is highly neurotoxic and no longer commercially produced. Commercial TCP is primarily meta- and para-isomer mixtures with tightly controlled ortho-content. TxCP is sometimes used as a generic abbreviation.

Q: Can TCP be used as a replacement for phthalate plasticizers?

A: Yes. TCP is an effective non-phthalate plasticizer offering superior flame retardancy and heat resistance compared to general-purpose phthalates (DOP, DINP). It is widely used in low-smoke, flame-retardant PVC compounds.

Q: Can TCP be used in food-contact applications?

A: Certain high-purity, low-ortho grades are FDA/EU 10/2011 approved for indirect food contact (e.g., conveyor belts).

Q: Is TCP still used in aviation hydraulic fluids?
A: While TCP was formerly used in aircraft hydraulic fluids (e.g., Skydrol competitor), most modern aviation fluids have transitioned to tributyl phosphate (TBP) or other safer phosphate esters. Industrial-grade TCP remains widely used in non-aviation applications.
