Triphenyl phosphite Use
chelating agent
Triphenyl phosphite is usually used as a chelating agent.
It has wide use in all kinds of PVC products.The products are like PE, PP, ABS, SBS.
Triphenyl phosphite keeps its transparency and inhibit the change of color.
It also improves antioxidant, light and heat stability for the main stabilizers.
Stabilizer
Triphenyl phosphite is commonly used as a stabilizer in polymer production.
It prevents degradation caused by heat, light or oxyge.
And it improves the performance and lifespan of plastic products.
Catalyst
Triphenyl phosphite can be a catalyst in various chemical reactions,
such as polyurethanes, acrylates and epoxies. It helps to increase the reaction rate, yield and selectivity.
Flame retardant
TPP has one use as a flame retardant in plastics, textiles, and other materials.
It reduces the flammability and smoke emission of these materials.
TPP improves their fire resistance.
Antioxidant
TPP antioxidant properties makes it useful in the food and pharmaceutical industries.
It prevents the oxidation and degradation of fats, oils and other organic compounds.
Intermediate
TPP is also an intermediate of pesticides, pharmaceuticals and fragrances.
