- 'High value CPVC manufacturing technology' Profitability to general purpose double profitability
- 'Hybrid metallocene catalytic system' High temperature and high pressure products available for 50 years
- 21st, New Technology Certification from National Technology Standards Agency

Hanwha Chemical (CEO Chang Chang-bum) has succeeded in developing two original technologies that will be future food. Hanwha Chemical has developed 'High Value CPVC (chlorinated PVC) manufacturing technology' A new metallocene hybrid catalyst system, which improves the physical properties of existing catalysts, was developed and obtained new technology certification from the National Institute of Standards and Technology. New technology certification is available for early commercialization It is a system that certifies the technology that can significantly improve the functions of existing products.

High value-added CPVC has increased chlorine content in existing PVC and is widely used for fire-fighting and industrial special pipes because it has excellent resistance to heat, pressure and corrosion. I need a high level of skill. Hanwha Chemical first domesticized the fact that only a few companies such as Lubrizol, Sekisui and Kaneka in the US relied on imports. Last year, the market size is about 630 billion won, growing steadily more than 10 every year. Profitability is more than twice that of general-purpose PVC. Less profitable and stable earnings.

The key to this technology is to increase the rate of absorption of chlorine by making many holes in the PVC, but by increasing the density so that there is no loss of production, the productivity is increased by 30. In addition, if this technology is applied to general-purpose PVC, it is expected to produce the world's best quality products. With the aim of commercial production in March next year, the Ulsan 2nd Factory is currently producing 30,000 tons CPVC plant is being built and the technology will be applied to Ningbo PVC factory in China. In addition, by constructing factories with their own technology, not technical alliances with foreign companies It will be possible to reduce the investment cost and operating cost as well as the possibility of exporting the technology.

Meanwhile, the 'metallocene hybrid catalyst system', which uses the characteristics of a metallocene catalyst called 'next generation catalyst', has also been developed. Metallocene is a catalyst used to produce chemicals. It is mainly used in high value products. The strength and processability of the existing catalysts using a single catalyst are significantly improved. This technology allows for 50 years of use at high temperatures and pressures. It is possible to produce the product and customized according to the purpose of the product.
