Benzoxazine resin

Introduction:

With solvent, Amine compounds react with phenol and formaldehyde and obtain a polymer with similar structure with phenol resin. Benzoxazine has flexible molecular structure, can turn into various monomers after adding different reagents. It has good thermal resistant, high glass transition temperature (>300℃) ,and no volume shrinkage or gas emission while curing.

Application:

It is used in printed circuit boards, CCLs, insulation boards, composite materials (eg.FRP and CFRP) and the interior for high speed rail & aircraft with other polymers.

Property: 

Model Appearance Free aniline (%) Softening point
