Mabuhay Vinyl Corporation is the first and largest chlor-alkali producer in the Philippines. It is the country’s leading manufacturer of caustic soda and hydrochloric acid and the only company that produces chlorine in commercial quantities. In addition, it supplies more than 50% of the country’s requirement for sodium hypochlorite. The products end up in the manufacture of many useful consumer products that are important in our daily lives. The company is backed by a team of technically skilled managers with long and extensive experience in the field of PVC and chlor-alkali production. Through the years, MVC continues to affirm its commitment to quality. After successfully passing stringent tests and inspection, its operations in Luzon, Visayas and Mindanao were all issued ISO 9002 certification – the internationally recognized standard of world-class quality.


Almost two decades after, Judge Guevara, with his son Victor, reorganized the company to produce two new products, caustic soda and polyvinyl chloride resin. A plant in Iligan, Mindanao, was set-up in 1965 through the Japanese Reparations Program. It engaged the technical services of Shin-Etsu Chemical Industry Co. Ltd. of Tokyo to assist its initial operation. The initial plant capacity was 4,000 MTPY for amalgam caustic soda and 6,000 MTPY for PVC resin. read more
