OUR LAB IS YOUR LAB
You can think of us as an extension of your R&D team. Our lab is your lab to enhance value by solving your manufacturing challenges and customizing polymer solutions, all part of the team’s day-to-day expertise. Here, in our lab, we continue to expand the knowledge base of nepheline syenite, microcrystalline silica, and air-floated kaolin to prove the technical advantages of our functional fillers compared to other minerals and to further your plastic product proficiency.

FULLY-FOCUSED ON RESPONSIBLE MINING
Covia manufactures HIFILL N at our Canada nepheline syenite plant (NSO), adhering to Environmental, Social, and Corporate Governance (ESG) principles. Long before ESG was a fundamental corporate conversation, Covia was leading the way with a vigorous social responsibility commitment to our team, communities, and planet. For example, our NSO plant is the fourth-longest standing member of the Wildlife Habitat Council with gold certification beginning in 1996. In addition to an environmental pledge, the staff donates time, talent, and funds to actively support our local communities.
