ABS polymer engineering plastics products in accordance with the performance and price increasing order, can be divided into general plastics, general engineering plastics and special engineering plastics three categories, and presents a pyramid-shaped distribution. The general-purpose plastic located at the bottom of the pyramid has a single performance, is relatively cheap, and is more common in daily life. General-purpose plastics include five major varieties, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile-butadiene-styrene copolymer (ABS). The general engineering plastics and special engineering plastics located in the middle and top of the pyramid have better performance and higher economic added value, and have huge market potential.

General engineering plastics include polycarbonate (PC), polyamide (PA), polyoxymethylene (POM), polybutylene terephthalate (PBT) and polyphenylene oxide (PPO); special engineering plastics include polyphenylene sulfide (PPS), liquid crystal polymer (LCP), polysulfone (PSF), polyimide (PI), polyaryletherketone (PEEK) and polyarylate (PAR).

Compared with general-purpose plastics, ABS polymer engineering plastics have greatly improved performance, such as high mechanical strength, high rigidity, good dimensional stability, good heat resistance, and excellent electrical insulation. Therefore, engineering plastic is a kind of plastic material that can be used as a structural material and withstand mechanical stress in a wide temperature range and in a harsh chemical and physical environment. The application of engineering plastics in the automotive industry is a good example of its excellent performance.

First of all, the use of engineering plastics can reduce the friction between automobile transmission parts, increase wear resistance, improve sealing, and enable automobiles to achieve greater breakthroughs in safety, comfort and fuel efficiency. Secondly, engineering plastics have the characteristics of light weight, strong plasticity, and low manufacturing cost, which greatly improves the integration of automobile parts and internal and external design space, while reducing the weight and manufacturing cost of the entire vehicle. Engineering plastics are not only used in automobile bumpers, dashboard panels, and door interiors, but also become the main materials in key components such as engine air ducts, throttle valve bodies, and intercoolers. As of 2012, 14% of the downstream demand for domestic engineering plastics came from the automobile manufacturing industry, while the proportion in Europe and the United States was close to 50%. Engineering plastics have become a better material choice for the automotive industry in the twenty-first century. Similarly, engineering plastics are also widely used in aerospace, electronic and electrical, automotive, petrochemical, national defense and military industries.

At present, the domestic engineering plastics industry is in a period of rapid development. After becoming a strong economic growth point of the chemical industry during the "Eleventh Five-Year Plan" period, engineering plastics, as a strategic emerging industry, has once again been included in the "Twelfth Five-Year Plan" development plan for the new material industry. Despite the rapid development, the annual output of domestic engineering plastics is still far from meeting the downstream demand.

In the process of the development of the engineering plastics industry and import substitution, enterprises that master the core technology will be able to fully benefit from the considerable returns brought by technical barriers and high added value of products, and achieve sustained and rapid growth together with the engineering plastics industry.

With the progress of science and technology and the continuous improvement of people's living standards, the traditional plastic manufacturing industry is undergoing a profound change. The force leading this change comes from an advanced polymer material-engineering plastics. The emergence of engineering plastics has brought higher performance products and broader application fields to the ABS polymer engineering plastics manufacturing industry.
