Is the widespread application of plastic products accidental
Plastic products were born in the early 20th century, the first synthetic resin in human history was born, and industrial production was realized. From then on, the development of artificial synthetic resin and plastic processing industry began.
The invention of catalyst and the development and synthesis of engineering plastics have created conditions for the rapid development of plastic products processing industry. Nowadays, plastic products have become an indispensable part of people’s life. With the development of household appliances, automobiles, engineering, construction, real estate and other industries, the market scale and development speed of plastic industry are also accelerating The trend of "replacing wood with plastic" and "replacing steel with plastic" is becoming more and more obvious in downstream industries, which makes them more and more widely used.
Plastics can be classified into engineering plastics, general plastics and special plastics.
Engineering plastics play an important role in the good development of plastics market. In recent years, engineering plastics have become the fastest growing material in the plastics industry. According to research and markets, the global engineering plastics market is expected to reach 97 billion US dollars by 2020. This will be an important driving force for the Asia Pacific composite market growth of 6.7% in 2015-2020. China has a relatively large market share and is the second fastest growing regional market in the Asia Pacific region.
Application growth, technological progress and rapid increase in demand in the Asia Pacific region have all driven the global demand for engineering plastics, which are used in many industries. Because of the excellent mechanical properties and heat resistance of engineering plastics, they have replaced traditional engineering materials such as wood and metal in many applications.
In addition to excellent strength and other properties, engineering plastics also have a feature: easy to produce. Therefore, engineering plastics are increasingly replacing traditional application materials in some fields, which will lead the market to further product innovation and material development.
Although individual plastic applications have different incentives in different metal substitution cases, generally speaking, the advantages of replacing metal with engineering plastics can be summarized as follows:
Weight reduction: the proportion of metal plastic substitutes is mostly below 1.7. It is lighter than steel and lighter metals such as aluminum. In general, carbon fiber reinforced plastics are more effective in weight loss.
Chemical resistance: high chemical resistance makes plastic parts more resistant to corrosion, rain, detergent and other substances than metal.
Cost saving: in terms of cost-effectiveness of the overall system, plastic parts may help to integrate several components, reduce the number of parts and assembly processes, or color the metal parts during injection molding to reduce the cost of polishing and coloring metal parts.
Suitable for more complex parts: when the complexity of parts increases, the process and cost rise of plastic parts is more moderate than that of metal parts.
Increase the degree of design freedom - plastic parts are more competent to produce complex shape design, with higher design freedom, which can enhance the uniqueness of brand or product.
Reduce scrap rate - plastic can be used to reduce multiple processes and recycling, which can help reduce scrap rate.
