PQ

High-quality, innovative silica for pharmaceutical applications

With more than 200 years of collaborative innovation, PQ partners with industry leaders to deliver high-quality, safe, and reliable solutions.

Our portfolio of silica excipients supports applications from API moisture protection and anti-caking to value-adding MADG processing.

PQ is a company with deeply ingrained core values.

Our five values are part of every decision we make, and are on display for our colleagues, stakeholders and communities.

One of our core values is that of safety.

Safety begins with our internal operations where we have an OSHA Total Recordable Incident rate in the top quartile of companies in the American Chemistry Council (ACC). Safety continues with our products, as our silicates make tires safer and improve performance, make concrete stronger while reducing dust by agglomerating powders, and aid in the delivery of safer drinking water by removing heavy metals. Our silicas allow the safe flowing of powder ingredients to enable accurate measuring and help capture moisture to keep contents dry to avoid spoilage.
