Poco Graphite Premium Graphite Glass Forming Graphite GF Graphite
Categories:	Carbon; Graphite
Material Notes:	GLASSMATE® GF is the base grade of glass forming materials with high strength and durability for glass forming applications. GF materials provide higher product yield through improved glass surface finishes and a match to high CTE glass products. Entegris POCO offers purification of each GM-GF material to allow for increased oxidation resistance through the elimination of metallic contaminates that react to oxygen present in the glass forming process. The purification process reduces impurities to 5 ppm (99.9995%) or less as determined by ash analysis. Features: World class microstructure. Higher level of interconnected porosity. Tighter correlation between particle and pore. Improved purity levels. Isotropic mechanical properties. Increased machining capabilities. Higher physical strength. Information provided by Entegris POCO Materials.
