The Linen-based grades also have higher density and good moisture resistance. Phenolic foams modified with different types and compositions of epoxy resin were successfully synthesized and characterized, showing uniform pore structure. Once benzoxazine resin is synthesized, the resin can be either thermally polymerized with or without initiators and/or catalysts. These `traditional' thermoset resins and developments of them have typically been cured at high temperatures (140-180OC) and usually high pressures. The model phenolic resins studied were synthesized using phenol, formaldehyde and one of three basic catalysts: triethylamine (TEA), aqueous ammonium hydroxide (28 wt. Benzoxazine resin possesses excellent flammability behavior which is similar to phenolic resins due to its nature of formation of a comparable network after polymerization.
