Polybenzoxazine Resins Market Volume Analysis, Segments, Value Share and Key Trends 2018 – 2026

Polybenzoxazine resins are a class of high-performance phenolic resins which are utilized in the structural and engineering applications because they possess good flame retardance and thermal properties of phenolic resins, including high mechanical properties, such as good sound and noise absorption. Polybenzoxazine resins are synthesized from phenol or substituted phenols, aldehyde, such as formaldehyde, acid aldehyde, or pyromucic aldehyde, and amine groups. They can be synthesized via either solvent or solventless technology. Benzoxazine is an intermediate from the oxygen-containing heterocyclic structures, synthesized from phenols, amines, and paraformaldehyde as raw materials. Its formation requires the ring-opening polymerization under the action of heating and / or catalyst, with no small molecules being released during the polymerization process.

This process forms a nitrogen-like and phenolic resin-like network structure of the polymer, namely polybenzoxazine or benzoxazine resin. Additionally, curing of the resins involves ring-opening polymerization without the need for a catalyst or curing agent for production. No by-product is obtained during curing, which leads to the absence of void in the products. Polybenzoxazine is a class of high-performance materials and possess the ability of alloying with other minor components is a crucial property for this novel kind of thermosetting, i.e., the properties of the rendered alloys and blends could be tailor-made to meet the requirements of any application. Polybenzoxazine resin can improve electrical and physical properties of its compound, as an additive to other resins. Moreover, it is effective as the resin of composite materials. Polybenzoxazine resins, when heated, homopolymerize to form a rigid polymer, which can be used for manufacturing products such as high-temperature composites and electronic components.
