The global chemical industry is shifting from general purpose products to high value-added products using technological innovations. Amidst this wave of change, Hanwha stands out for successfully developing two new technologies. Each technology has earned the New Excellent Technology (NET) certificate in December of 2016. The NET certification is a prestigious title given by the Korean Agency for Technology and Standards (KATS) to newly developed technologies. The recognitions effectively put Hanwha on the map as a technology powerhouse.
The research teams of Hanwha Chemical R&D Center have played a pivotal role in obtaining these certificates. They serve as the backbone of Hanwha’s efforts in laying the foundation for becoming a global leader in the chemicals market through the proprietary development of original technologies.
The NET-certified CPVC manufacturing technology using PVC modification and high-efficiency neutralization drastically improves the productivity and workability of CPVC. An extensive range of plastic goods that we use daily are made of PVC. CPVC is PVC polymer infused with 10% more chlorine to make it highly resistant to heat, pressure, and corrosion. CPVC is widely used for their heat and chemical-resistant characteristics and is the best material for sprinkler piping, hot water pipes, and specialized pipes for industrial liquid handling.
The Hanwha Chemical R&D Center’s principal research engineer Seon Jeong Jin is the leader of the CPVC project and he said, “The key to the successful development of the proprietary technology was our ability to apply chemical materials to extremely diverse applications. Our goal was to discover the base PVC resin suited for the CPVC development process. Based on our technical capability and the knowhow we accumulated over the past 20 years on PVC, we were able to develop a resin that accelerates chlorination and neutralization of by-products while maximizing the amount of extrusion. This discovery led to our breakthrough in CPVC manufacturing technology.”
The global demand for CPVC is increasing. Hanwha Chemical’s effective CPVC manufacturing technology will help the company meet the increasing global demand for CPVC. CPVC has 15% higher productivity compared to traditional methods.
Hanwha Chemical completed a CPVC production plant in Ulsan, Korea. This plant began production in March of this year and has the capacity to produce up to 30,000 tons of CPVC per year. And by adding the CPVC production line at the Ningbo plant in China, Hanwha Chemical plans to double this number to 60,000 tons per year by 2020.
The Hanwha Chemical research team has also launched a project to improve the quality of standard PVC by applying new CPVC technology to the PVC lines it currently operates. The team’s extensive research and development efforts are expected to be recognized as a model case-study to show the rest of the petrochemical industry on how to add value to general purpose products.
First-generation metallocene has high mechanical strength but poor machinability, whereas the second-generation of the substance has better machinability but lower strength.
The new high-activity metallocene represents a breakthrough, overcoming the shortcomings of both metallocene generations by being stronger mechanically and having great machinability. It is for this reason that the new metallocene is dubbed the “dream catalyst” or the “catalyst of the future.”
The Hanwha Chemical research team made a strategic move to focus on the development of metallocene for MDPE/HDPE in order to secure a competitive edge in the global market. Currently, 95 percent of metallocene is being used for making films that are widely adopted in food packaging and containers, and this innovative push resulted in the successful development of a totally new material demonstrating optimal strength and machinability.
“While most petrochemical companies focus on developing technology and expanding their market shares of metallocene for film production, we have been dedicating our efforts to the development of a technology targeting MDPE/HDPE, an unexplored area in the field of metallocene. Moreover, we leveraged the gas-phase PE production system already under operation by Hanwha’s petrochemicals division to secure a more cost-competitive and ecofriendly technology than the existing slurry production system of our competitors. We expect the hybrid metallocene method to boost the productivity of the plastics industry at large.”
And while continuing their work on these projects, research teams at the Hanwha Chemical R&D Center are increasing their efforts to advance Hanwha Chemical’s core competency by developing more cutting-edge technologies. In so doing, the company will not only join the global petrochemical industry shift to the manufacture of high value-added products, but also lead it.
