Ultra-Pure Graphite Paper

Ultra-Pure Graphite Paper (UPS-GRADE) is a new generation product from Shanghai Oneshine. Through high-temperature purification methods and strict quality control, the mass-produced ash content is reduced to below 1ppm, helping photovoltaic crystal pulling to reduce costs and increase production efficiency. At the same time, it meets the stringent purity requirements for semiconductor crystal pulling, with the ash content currently achievable at 0.88ppm.
