Flammability studies were also performed on glass fiber laminates manufactured from these resins. Phenolic resin is fire resistant to some degree. SJAjith Kumar . Each of the tandem composites consist of nano-zirconium dioxide with small amounts … Phenolic resins, originally developed in the late 19th century and, regarded as the first truly synthetic polymer types, are often referred to as the “work-horse of thermosetting resins”. Burning phenolic resin typically generates hydrogen, hydrocarbons, water vapor, and carbon dioxide. These stages were attributed to the evolution of water, the volatilization of species loosely bound to the phenolic backbone, and bulk degradation of the phenolic matrix. Phenolic resins (Phenoplasts) are synthetic thermosetting resins invented by Dr. Leo Baekeland in 1907. Manufacturers use phenolic resins extensively to address the safety concerns of … It is a good electrical insulating material meeting the requirements of BS EN 60893-3-4 Type PF CP 206 (and the former BS 2572 Type P3) and it also meets Class FV0 flammability in the BS 6334 (IEC 707) test.
