New polymer offers surface similar to Teflon but without use of fluorocarbons

A new polymer with propoerties similar to Teflon has been unveiled. Speaking at the conference, Case Western Reserve University (CWRU) professor Hatsuo Ishida, outlined the characteristics of the new polymer- polybenzoxazine. Polybenzoxazine is at the level of being commercialised because it offered unusual properties that one would not find in other thermosets. It was favourable to epoxy and phenolics, he added, as per “It has an enormously rich molecular design flexibility that allows tailoring an extremely wide range of properties,” Ishida said. Polybenzoxazine offered some big benefits, he added, including near-zero volumetric changes or expansion, cross-linked density but with a very high modulus, and a surface similar to Teflon, but without using fluorocarbons. The material had very good thermal stability and flexural strength, and it is non-igniting. Key markets include aerospace, energy, and electronic packaging.
