PQ Corporation is a leading global producer of silicate, zeolite, and other performance materials serving the detergent, pulp and paper, chemical, petroleum, catalyst, water treatment, construction, and beverage markets. Our chemical products are complemented by those of our former subsidiary Potters Industries, a leading producer of engineered glass materials serving the highway safety, polymer additive, metal finishing, and conductive particle markets.

PQ Corporation was founded in 1831 and was known as the Philadelphia Quartz Company from 1864 until 1978. The values of our founders - integrity and fairness, diligence and service, learning and imagination - are still reflected in our contemporary corporate culture. We believe that this culture and the strong spirit of teamwork it fosters are of immense benefit to our customers, our employees, and our suppliers alike.

Build on PQ’s (National Silicates) global leadership in providing customer solutions through our knowledge of silica-based chemistry, performance materials, and technical service excellence.
