Propilven's polypropylene production process is continuous and, as its main raw material, it uses the propylene which is produced by the Olefin's Plant of Zulia's Petrochemical Complex.
The technology belongs to the Japanese company Mitsui Chemicals Inc. and it is worldwide known as "Hypol Process". This production technology is characterized by the use of high-performance catalysts, two-phase polymerization and a wide range of products.
In the Hypol process, the raw material and the catalysts are continuously introduced into the reaction section (two reactors in the liquid phase and two in the gaseous phase). Propylene polymerizes and forms a polypropylene powder, which is dried to eliminate the volatile material; it is blended with different additives depending on the application and it is subject to an extrusion process where it is transformed into granules or "pellets", which are later on transported to the homogenizing silos. Granules are finally packed and stored for their delivery later.
The final product is delivered to customers directly from our warehouse located at El Tablazo or from an alternate warehouse located in Los Guayos, Carabobo State , in the center of the country.
