Application
The main uses of 3-Hydroxyphenylphosphinyl-propanoic acid(CEPPA) are as follows:
Environmentally friendly flame retardant:
As a new environmentally friendly halogen-free flame retardant, its core function is to enhance the flame retardant performance of polyester fibers. By copolymerizing with polyester chips, the flame retardant effect can be significantly enhanced, with a maximum oxygen index of 30-36%, while maintaining the spinnability of polyester.
Industrial resin modification:
By condensing with organic amine compounds, polymer resins (such as nylon PA) can be modified to improve their flame retardancy, thermal stability, and mechanical properties.
Other applications:
Organophosphorus pesticides: CEPPA can be used for synthesizing phosphorus containing pesticides.
Plasticizer: CEPPA enhances the processing performance of plastics.
Antioxidants: CEPPA can delay material aging.
Catalyst: CEPPA can promote chemical reactions.
