Red phosphorus, comparatively harmless, is used in matches. Phosphorus, a combination of phosphorus with iron, is used as an ingredient in high-strength low-alloy steel.

Product Description

DovaFR P4-red is an allotrope of element. It is nontoxic, odorless and active chemically, though not highly. It is dark red, and unlike white phosphorus, is not phosphorescent. It has a variety of applications in industry, such as matches, fireworks and especially in Flame retardant.

Benefits

1. DovaFR P4-red is a fine red or auburn amorphous powderwith high purity.
2. DovaFR P4-red is made of low arsenic Yellow phosphorus (P4 yellow), which makes product more purity than others.
3. DovaFR P4-red is applied in thermoplastics and thermosets as a very effective flame retardant (N-P based).
4. DovaFR P4-red is with excellent properties with its strictly standard.

Applications

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.
