Cristobalite helps in film applicationsCristobalite helps in film applications

Used in polyethylene or ethylene-vinyl acetate films, quartz-derived cristobalite acts as an antiblocking agent and provides IR absorbing properties. It is chemically inert and has a neutral white color. Particle size runs from 3 to 60 µm. It can also be surface treated. SCR-Sibelco NV, 49 Quellinstraat, B-2018 Antwerp, Belgium www.sibelco.bc
