PVC is the world‘s second largest, and China’s largest plastic raw material, occupying an important position in the national economy and people's livelihood. At present, China has been the world's first largest PVC manufacturing country. In 2014, the actual production was more than 15 million tons, most of which was PVC for general purposes. The annual output of special PV was less than 100,000 tons, in a single variety. With respect to PVC for general purposes, the PVC industry in China leads the world in productive capacity, but the industry of special PVC still has a large gap compared to international output, both in variety and quality. Therefore, the special PVC is still in the development stage in China, but its prospect should not be underestimated.
The reasons for slow domestic development of special PVC include:
Domestic PVC manufacturing enterprises have large production equipment, unsuitable for manufacturing special specifications.
The understanding of the development prospect of special PVC should still be improved.
The technological development for special PVC is not in place yet.
Zhengbang Technology has a perseptive understanding for special PVC, and started R&D as early as five years ago, by combination of foreign technologies and domestic PVC production equipment for rapid involvement and development.
After hard efforts for several years, starting from scratch and developing gradually, Zhengbang Technology has now developed into a leading enterprise manufacturing special PVC in China, and a manufacturer of viscosity-reducing PVC resin with the largest productive capacity, the most complete variety and leading quality in China.
