Performance Chemicals

PQ Corporation’s performance chemicals are crucial ingredients in a diverse set of industrial and consumer products. Our performance chemicals act as cleaning and whitening agents in toothpaste, create a “matted” finish on surface coatings and remove impurities from beer and edible oils.

Performance Materials

Our Potters® brand microspheres are used in wide variety of transportation safety applications including engineered glass microspheres that increase brightness and visibility of highway and airport pavement markings. Our ThermoDropTM thermoplastic product is revolutionizing the process of applying stripes on highways and roadways. Additionally, we produce solid and hollow microspheres that increase the strength of resins while reducing their weight and metal coated particles that diminish electromagnetic interference in electronics.

Refining Services

Corporation’s refining services are responsible for recycling millions of tons of spent sulfuric acid for refineries each year. Sulfuric acid is the primary catalyst used in the production of alkylates for gasoline production at refineries. Alkylates are a critical material used to increase octane in gasoline at low vapor pressure and currently are used in most gasoline in the United States.

Catalyst

In our Silica Catalysts product group, we offer both the finished catalyst and catalyst supports that are critical in the production of plastics used in packaging films, bottles and containers and other molded applications. We also produce a catalyst that can be used in the manufacture of MMA, a scratch-resistant plastic used to replace glass and as a durable surface coating. These catalysts also reduce the energy needed for the manufacture of plastics with less waste.

Our Zeolite Catalysts product group is a leading global supplier of emissions control catalysts and specialty catalysts, precursors and formulations to refineries and downstream petrochemical and chemical companies. We produce catalysts that reduce air pollution from diesel vehicle emissions and cut the amount of sulfur in gasoline. For nearly three decades, we’ve operated this group through our Zeolyst partnership.
