Catalysis Products
While ordinary commercial styrene-based sulfonic acid resins may often be used for chemical reactions catalyzed by the H+ or M+ ions, faster process times, better yields, and higher product purity may be obtained by using a properly designed and purified catalyst. Purolite catalyst resins are supplied either completely water-swollen, or dried to specification.
Our catalyst products are used in many applications in the chemical and petrochemical industries.
