Moldex Products, Inc. (MPI) resulted from a proprietorship business organized by Mr. Jacinto Uy in the mid-sixties. The company’s initial operations involved reprocessing of plastic materials into pellets, which the firm sold to downstream product manufacturers. After a few years, the proprietorship business graduated from reprocessing of plastic materials to the production of plastic seals and PVC bottle compounds. PVC bottle compounds were then used as raw materials to produce clear and transparent plastic bottles which are good for glass bottles for hair care products, toiletries and other similar type of applications.
On 17 March 1972, the proprietorship business was incorporated and registered with the SEC. The production of rigid PVC plastic film was introduced as a new product line. Two extruder lines were acquired from Japan. United Laboratories, Inc. was the firm’s first client. The large pharmaceutical company made use of the PVC film as material for blister packing its various pharmaceutical products. Subsequently, a substantial number of other local pharmaceutical companies followed suit making Moldex the principal supplier of rigid uPVC film in the industry.
In early 1979, MPI diversified into the manufacture of PVC, polyethylene (PE), and polybutylene (PB) pipes and tubings. Much later, other product lines were introduced. These included corrugated electrical and telecom conduits as well as branded drain, waste and vent (DWV) pipes and fittings. The markets for these products are varied as they have industrial, commercial, and residential applications.
Given its continued insistence for the manufacture of quality products, MPI today is recognized as the market leader and quality producer in the PVC pipes industry and a BOI-registered budding exporter of uPVC rigid film.

MPI’s principal offices are located in a 9-storey building along Ligaya Street corner West Avenue, Quezon City.
The MPI manufacturing facilities are now located in Marilao, Bulacan. The entire site contains a total area of 20 hectares. Only 6.6 hectares are occupied leaving ample space for future expansion. The transfer from its previous 3.3-hectare plant in Valenzuela, Bulacan was completed in 1996 following the implementation of MPI’s expansion and modernization program for its pipes and PVC film businesses. The new plant site is in the industrial zone of Moldex Realty, Inc.’s development project in Marilao, Bulacan. Electric power, water supply and communications are available at the site. It is accessible to public transportation. Well-built structures designed for a comfortable and sanitary environment serve to house the various production lines, warehousing and administrative needs. The structures were designed together with U.S. based engineers to withstand typhoons, minimize entry of dust and reduce temperature in the work areas. All roadways within the factory are concreted and amply provided with appropriate drainage systems and culverts. The expansion project passed the scrutiny of OECF, the Japan-Exim Bank and the ADB. These international financing institutions were sources of peso denominated long-term loans through DBP’s wholesale lending program. The company’s film’s plant also received its ISO 9002 accreditation in March 1997 that was important in entering the world export market.

With nearly forty years experience in the manufacture of plastic products, MPI has developed a reliable network for its raw materials, spare parts, and other supply requirements. In terms of cost, PVC resin is the company’s principal raw material requirement. These are procured locally and from abroad. Inventory levels are determined based on MPI’s readings of price trends that have become an intrinsic part of MPI’s operational procedures. MPI similarly adopts at the least a two-supplier policy in order to maintain integrity of pricing and to keep alternative sources of supply.
