Polypropylene (PP for short) is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion. It is widely used in industry and is one of the common polymer materials.
PP application purposes: 1. Film products: PP film products are transparent and shiny, with low permeability to water vapor and air. It is divided into blown film, cast film (CPP), biaxially oriented film (BOPP), etc. 2. Injection molding products: can be used for automotive, electrical, mechanical, instrumentation, radio, textile, and other engineering accessories, daily necessities, turnover boxes, sanitary equipment, and building materials. 3. Extruded products: pipes, profiles, monofilaments, fishing ropes, packing belts, binding ropes, woven bags, fibers, composite coatings, sheets, plates, etc., blow molding hollow molding products, various small containers, etc. .
PP is a translucent, crystalline propylene polymer that combines excellent heat and chemical resistance with a good balance of rigidity and impact resistance. Impact-resistant PP comes in varying levels of rigidity and impact strength. It has good performance at low and high temperatures. For the demanding automotive, electrical and industrial markets, impact-resistant PP is an ideal choice.
