What is Modified Plastics



Modified plastics refer to the plastics products which are processed on the basis of general plastics and engineering plastics by filling, blending and reinforcing methods to improve their flame retardancy, strength, impact resistance and toughness.



Modified plastic parts can not only achieve the strength properties of some steel products, but also have a series of advantages, such as light weight, rich color and easy forming. Therefore, the trend of replacing steel with plastics has emerged in many industries, and it is almost impossible to find a large-scale material to replace plastic products at this stage.



Modified plastics are intermediate products in petrochemical industry chain. They are mainly processed from five general plastics and five engineering plastics. They are flame retardant, impact resistant, high toughness and easy to process. Modified plastics is a typical beneficiary industry of technological progress and consumption upgrading. Thanks to the accelerated transfer of global production capacity of household appliances, computers, electric tools and toys to China, China has become a major manufacturing country in these fields, relying on its cost advantages in terms of labor force and other factors of production, thus promoting the development of domestic modified plastics industry. Consumption upgrading has brought China's automotive and construction industries into a period of rapid growth. With the continuous improvement of material performance requirements, China is becoming a potential market and the main driving force of demand growth for modified plastics in the world.



According to "Analysis Report on Production and Marketing Demand and Investment Forecast of Modified Plastics Industry in China from 2013 to 2017"

[1]

Data analysis shows that in recent years, China's modified plastics industry has developed rapidly, with annual average growth of output and apparent consumption reaching 20% and 15%, respectively. At present, the total annual demand for modified plastics in China is about 5 million tons, accounting for about 10% of the total plastic consumption, but still far below the world average level of 20%. In addition, the per capita plastic consumption in China is still far behind that in developed countries. As an index to measure the development level of a country's plastics industry, the ratio of plastics to steel in China is only 30:70, which is less than the world average of 50:50, and far less than that in developed countries such as the United States of America's 70:30 and Germany's 63:37.



At present, the development level of modified plastics industry in China is relatively low. The production scale of enterprises in the industry is generally small. The market situation of products also shows that there are many primary products, the quality of intermediate products is unstable, and the lack of advanced products, which is far from meeting the needs of the economic development of China in the 21st century. Therefore, as an important part of new chemical materials, modified plastics have also been listed as one of the key areas of science and technology. Since 2007, China has issued various policies to promote the development of modified plastics industry.

With the rapid improvement of people's living standards and the progress of technological means, it will become a trend to replace wood with plastic instead of steel in China. According to the survey of Prospective Net, the modified plastics industry, as a sub-industry of the plastic processing industry, is developing rapidly and has great potential for development. It is expected that the total market demand of the modified plastics industry will still maintain a growth rate of more than 10% in the next five years.




Modified plastics is a field of plastics industry which involves a wide range of fields, has high scientific and technological content and can create huge economic benefits. And plastic modification technology - filling, blending and strengthening modification is in-depth processing of raw materials and moulding of almost all plastic products. From the production of raw resin to the modification of plastic masterbatches of various specifications and varieties, in order to reduce the cost of plastic products and improve their functionality, plastic modification technology is indispensable
