Greener glass

As the glass industry looks for new ways to reduce its environmental footprint, Sibelco’s MATRIX® helps manufacturers to bring down energy consumption.

MATRIX® harnesses the natural properties of nepheline syenite, a mineral noted for its low-iron content and high chemical stability. Mined and processed from our unique deposit in Norway, MATRIX® is used within the glass batch to promote faster melting at lower temperatures whilst at the same time decreasing viscosity. Its addition therefore helps to reduce overall energy consumption.

Thanks to a naturally high alumina content, MATRIX® can deliver the same results as alternative products but using between 20-30% less volume of material. This means a lower transport and storage footprint.

As well as energy saving benefits, MATRIX® increases the chemical resistance and stability of the finished glass. And when colour control is critical, the physical and chemical properties of MATRIX® ensure clearer glass without the need for additives or decolourisers.
