Benzoxazine Polymer



Indian Space Research Organisation at its Sarabhai Space Centre has developed Benzoxazine Polymer,a matrix resin suitable for thermal insulations, adhesive formulations and encapsulant in PCB industry. Polybenzoxazine is a suitable candidate matrix resin for high density ablative composites and also for light weight foam composites in aerospace applications due to excellent thermal and thermo-oxidative stability, high char yield, good chemical inertness, abrasion resistance and flame retardancy. It also finds application as an encapsulant in electronic industry. industry.
