Multi-grade PP film special material industrialization project developed successfully
The industrial development project of multi-grade PP film special materials undertaken by Lanzhou Chemical Research Center of PetroChina petrochemical research institute has passed the appraisal, the expert group recommended that the project should expand the scale of industrial production as soon as possible.
at present, there is a big gap in the domestic polypropylene film market. In order to meet the demand of domestic polypropylene film market and improve the differentiation rate of polypropylene products, Lanzhou Chemical Research Center and Lanzhou Petrochemical Company jointly developed a special material for polypropylene film.
through the optimization of polymerization process, granulation process and additive system, special materials for polypropylene film F500 and F600 were successfully developed on the 110 thousand t/a polypropylene plant of Langang company, it has solved the problems of high ash content and many fisheye in the production process of special resin for polypropylene film, and has effectively improved the product quality. It has successively produced more than 20 thousand tons of F500 biaxial stretch polypropylene special material, f600 salivary polypropylene special material more than 10 thousand tons. The multi-grade polypropylene film special material industrialization project not only optimized the structure of polyolefin products of Lanzhou Petrochemical Company, but also created economic benefits for the company and became a market.
