GLASS-FIBRE FILLED POLITEF® The most important properties of glass-fibre filled POLITEF alloys are high heat resistance, corrosion resistance, high resistance of deformity under load , high electric isolation, dimension stability, easy processing. Mostly used areas are pre-fabric houses and bathroom equipments.The most developing parts are used at plane and space industry. On the other hand, it is commonly used recently at electrical industry, at sea vehicles, at land transport, at sports equipment sector.
