We offer our customers in the electrical and electronic industries numerous material solutions based on high purity quartz and silica. Our minerals include crystalline silica, fused silica, spherical silica, surface treatment of silicate fillers and engineered products. Our engineered minerals represent a diverse selection of physical, chemical and functional properties. They are proven performers for epoxy moulding compound (EMC), copper clad laminate (CCL), electrical insulations, electrical encapsulation and thermal interface materials (TIM).

Our Technical Centre is fully equipped with test facilities to conduct research on performance filler formulation and application performance. We address your specific needs by offering a global approach, based on tailor-made solutions. Whether you’re looking for solutions to improve factors like insulation, dimension stability or thermal conductivity, we will strive to find the best solution for you.
