At the Ulsan site in Korea, BASF will switch the plant´s entire 85,000 metric tons capacity from the classic white EPS (expandable polystyrene) Styropor to the improved insulation raw material Neopor (gray EPS) until end of 2018. This will allow the company to meet the growing demand for the gray material in the Asian market.
After a series of debottlenecking measures, the Ludwigshafen plant is now capable of producing 200,000 metric tons of Neopor a year. The annual production capacity for Styropor and Neopor at this location has been increased from 440,000 to a total of 460,000 metric tons.
The trend towards grayThe raw material is processed into insulation boards, which contribute to substantial savings of heating energy in new construction and renovations. Thus, the demand has risen steadily worldwide. Since introducing the product in 1998, BASF has continuously adapted Neopor´s production capacity. Compared with Styropor, the graphite containing insulation boards offer better insulation performance. Due to the lower density, lighter boards can be produced, making construction more efficient and saving material at the same time.
“With this step, we are offering even more customers a product that has been further developed in economic as well as environmental terms to meet the challenges we face with regard to climate protection and resource conservation. Worldwide, around 45% of total oil consumption and CO2 emissions - 40% in Germany - is caused by the heating and cooling of buildings. This can be significantly reduced by comprehensive, efficient insulation, supplemented by optimized building equipment and the appropriate use of alternative energy sources,” said Klaus Ries, Head of Global Business Management Styrenic Foams at BASF.
Inventor of white and gray EPSBASF invented and patented Styropor, the well-known, white foam granulate, in 1951, and launched Neopor 20 years ago as the first graphite containing EPS. The gray, plastic granulate Neopor is an advanced version of the classic white insulation material Styropor. By adding graphite, which gives the material its gray color, the insulation performance of the boards is increased by up to 20%. The use of raw material drops by up to 40% compared with the white material. This enables the processor to produce insulation boards with a lower mass but better insulation performance. The finished insulation products made of Neopor can be used in a range of applications, particularly for insulating exterior and interior walls and flat roofs.
