What is the price of polypropylene melt-blown material?

1. Polypropylene products are one of the three major plastic products, which are used in all aspects of life, from the bottle caps of water cups to automobile supplies. However, the production of this basic industrial product, which involves the national economy and people's livelihood, has been controlled by foreign patent technology manufacturers for many years.

2. Polypropylene production processes mainly include solution method, slurry method, bulk method, gas phase method and bulk gas combination method. At present, the more advanced production processes in the world are mainly gas phase method and bulk gas phase combined method. These processes all adopt bulk method, gas phase method or bulk-gas phase combination method to produce homopolymer and random polymer, and then connect gas phase reactor systems (one or two) in series to produce impact-resistant polymer.

3. These technologies meet the requirements of large-scale plant (more than 200,000 tons/year), economic operation, product diversification and high performance, and have been widely used.
