From March 12th to 16th, 2019, Jiangxi Aote attended the 25th Seoul International Plastics and Rubber Exhibition held at the International KINTEX Exhibition Center in Seoul, South Korea. This exhibition brings together more than 800 exhibiting companies from more than 30 countries around the world, mainly exhibiting plastic and rubber products, chemical raw materials, auxiliaries and auxiliary materials, machinery and equipment, testing instruments, etc., and nearly 100,000 visitors. The exhibition is the largest plastics and rubber exhibition in South Korea, and also an important plastics and rubber exhibition in Asia.

The export proportion of resin in South Korea has been maintained at more than 40%. At present, China, with the rapid growth of plastic resin demand, has become the second domestic market in the eyes of Korean chemical enterprises, ranking the second in the plastic export market in South Korea. Since 1982, South Korea's plastic production and sales have continued to grow. At present, there are more than 4000 plastic and rubber enterprises in South Korea, with an annual market size of 5 billion US dollars, maintaining a continuous upward momentum every year. Recently, the export volume of automobile, home appliances and other industries has increased greatly. All industries are committed to reducing human resource costs, improving technology content and realizing production automation, so as to strengthen international competitiveness. The exhibition is an important platform for Chinese enterprises to explore Korean market and participate in international technical exchanges.

Wollastonite is a chain-like metasilicate mineral with the chemical formula CaSiO3. There are two variants of high temperature and low temperature. Generally, wollastonite refers to the high temperature variant. Natural wollastonite is usually white or off-white, has glass or pearl luster, density is 2.78 ～ 2.91g / cm3, hardness is 4.5 ～ 5.0, usually needle-like or fibrous aggregate, even small particles can still maintain fibrous structure .

Wollastonite is rich in resources and low in cost. Its unique structure and properties give excellent performance to plastic products, expanding the application fields of plastic products. Polymers are mostly petroleum cracking products, while wollastonite is widely used in plastics. Application can save synthetic resin, make full use of limited petroleum resources, reduce production costs, and bring considerable economic benefits to enterprises.
