Applications
DovaFR P4-red is as an ideal halogen-free Flame retardant in thermoplastic (e.g. polyamide) and thermosets (e.g. epoxy resins or polyurethanes) base on its high content of P. Phosphorus is the element with the most fire retardant effect among all elements so that it can efficiently obtain a fire retardant effect with small quantities. This makes it possible to minimize the degradation of the physical properties of the resin.
In other industry, DovaFR P4-red is applied in fireworks, matches, organic synthesis, medicine, synthetic material, pesticide and et.
