The Development Prospects of the Four Major Plastic Products

With the rapid development of China's national economy, China will focus on the development of four major categories of agricultural plastic, packaging plastic, construction plastic and engineering plastic products in the future according to the national key development plan.
 
Agricultural plastic products
China focuses on the development of various functional greenhouse films, mulch films and forage films required for the cultivation of vegetables, flowers and commercial crops. In terms of water conservancy, water-saving irrigation equipment, channel anti-seepage pipes and anti-seepage films, and different types of micro-irrigation such as drip irrigation, micro-spray and infiltration pipes equipment to meet the needs of water-saving agricultural development.
 
Packaging plastic products
Focus on the development of plastic packaging products or various food, beverages and medicines, which mainly focuses on packaging materials with good protection, hot-fill packaging materials, fresh-keeping materials, and anti-mildew and insect-proof materials for grain storage to improve the protection function and prolong the service life of the goods. With the improved performance of plastic materials in terms of hardness, heat resistance and toughness, the food and beverage industries are increasingly using plastic packaging materials to replace traditional paper, glass and metal packaging. The fastest sales growth expected is polypropylene packaging, while the markets for polystyrene and flexible polyvinyl chloride (PVC) are expected to grow the least. At the same time, with the improvement of the performance of the molding process for the transparent plastic polymethyl methacrylate (plexiglass PMMA), polycarbonate (PC), polyethylene terephthalate (PET), polystyrene (PS), AS (acrylonitrile benzene) ethylene copolymer) and polysulfone (PSF), the use of transparent plastic products will become more and more extensive.
 
Polycarbonate (PC) resin is the fastest-growing general-purpose engineering plastic in recent years due to its outstanding impact resistance, creep resistance and dimensional stability, heat resistance, low water absorption, non-toxicity, and excellent dielectric properties. It is currently widely used in electrical and electronic, automobile, office equipment, packaging, construction, medical care, sports equipment and other fields. With the continuous deepening of modification research of materials and the improvement of the performance of the molding process, PC is rapidly expanding to high-tech fields such as computers, optical discs, and aerospace.
 
Building plastic products
Focus on the development of various types of pipes, pipe fittings and profiles (doors and windows) that are suitable for different regions and different building types with serialized and standardized building facilities, such as large-diameter upper and lower water pipes, new indoor water pipes, hot water pipes, gas pipes and composite pipes. composite profiles, various thermal insulation materials, waterproof materials, wall decoration materials, building interlayer plastic molding plates for roof greening, etc. Because China has banned the use of cast iron pipes and replaced them with plastic pipes, it is estimated that in 2010, 80% of the indoor drainage pipes of new residential buildings and 50% of the urban water supply will use plastic pipes. In the construction and building materials industry, the popularizing rate of plastic doors and windows is 30%, and that of plastic pipes will reach 50%.
 
Engineering plastic products
The application of engineering plastics has expanded from being mainly limited to aerospace, atomic energy and other cutting-edge defense technologies, electrical and electronic, automobiles, instrumentation and other fields to fields of the national economy and all aspects of people's lives such as various machinery, office equipment, information industry, building materials, signal lighting, food processing, medical equipment, cultural entertainment and sports equipment and daily necessities. It is precise because of the vigorous development of related manufacturing industries that the demand for engineering plastics products in China has risen sharply. China's engineering plastics industry is entering a boom in production and demand. Engineering plastics generally refer to plastics that can be used as structural materials to withstand mechanical stress and can be used in a wide temperature range and harsh chemical and physical environments. Engineering plastics can be divided into general engineering plastics and special engineering plastics. General engineering plastics usually refer to five plastics that have been industrially produced on a large scale and have a wide range of applications, namely polycarbonate (PC), polyamide (nylon, PA), polyoxymethylene (POM), polyester (mainly PBT and PET) and polyphenylene ether (PPO). The main application market of engineering plastics and its share are electronic and electrical 25%, automobile 22%, machinery 20%, daily consumer goods 10%, and other 23%. Internationally, the development of engineering plastics is very rapid, with an annual growth rate of 7% to 10%. Among them, the application and output of polycarbonate still rank first among the five general engineering plastics.
 
With the accelerated pace of product replacement in various industries, plastics have the advantages of being able to form any shape, high productivity, and low costs, and plastic products will be more widely used; only the automotive industry requires a variety of plastic products with 36 tons. Among the above products, the production of key categories such as pipes, profiles, calendered products, films, and engineering plastic products will gradually develop towards the direction of the economic scale.
