The Quartz Roller MH (model QU-RO99) from Moat City is crafted from high-purity fused silica, offering superior chemical resistance and thermal stability. With a refractoriness up to 1710 °C, low thermal expansion (~0.6×10⁻⁶ K⁻¹), and strong mechanical strength (≥ 80 MPa compressive), it ensures robust, contamination-free performance in high-temperature furnace, semiconductor, and industrial applications.
