News Release. New welding technology for thick insulation boards

Transcription

1 News Release New welding technology for thick insulation boards Combinations of different insulation materials are possible Highly compression-proof Styrodur boards (XPS) up to 240 mm available June 28, 2016 P244/16e Andrea Decker Communications Performance Materials Phone: BASF has worked with a well-known machine manufacturer to develop a new technology for welding insulation boards. The contactless, thermal welding process makes it possible to combine a variety of insulation materials. For example, Styrodur, the extruded rigid polystyrene foam from BASF, can be combined with polyurethane, the inorganic aerogel SLENTEX, or the melamine resin foam Basotect to form completely new insulation material solutions. The Styrodur portfolio also includes new, especially thick boards made using this process in the highly compression-proof varieties Styrodur 4000 CS and 5000 CS. The boards cover the thickness range from 60 mm to 240 mm with a consistently good insulation value (lambda: W/(m K)). BASF at K 2016 Hall 5, booth C21/D21 basf.com/k2016 Advantages for the construction industry Architects, planners, and craftsmen benefit from the new possibilities: the traditional advantages of the Styrodur board, such as low water absorption and high compressive strength, can be combined with the desirable properties of other building products. BASF has already patented a range of applications and product combinations. On this basis, the company is seeking to develop and advance new applications in building insulation together with interested partners.

We combine economic success with environmental protection and social responsibility. The approximately 112,000 employees in the BASF Group work on contributing to the success of our customers in nearly all sectors and almost every country in the world. Our portfolio is organised into five segments: Chemicals, Performance Products, Functional Materials & s, Agricultural s, and Oil & Gas. BASF generated sales of more than 70 billion in BASF shares are traded on the stock exchanges in Frankfurt (BAS), London (BFA), and Zurich (AN). Further information at: About Styrodur The compression-proof, water-repellent, and rot-proof Styrodur has protected homes from heat, cold, and moisture for more than 50 years. The green XPS is characterised by its reliable product quality as well as the continuous efforts to gain approvals. Today, Styrodur is the insulation material with the greatest number of officially approved uses in the German XPS market. Insulation with Styrodur prolongs the lifespan of buildings, increases their value, and improves the living environment. The various Styrodur types, which contain air as the cell gas, differ mainly in their compressive strength. You can find more information on Styrodur on the homepage (

3 New technology Styrodur welding Thomas Kiciak Technical Business Development & Marketing Styrodur BASF SE What is Styrodur Styrodur can look back on more than 50 years of experience at BASF in Ludwigshafen and belongs to the group of extruded rigid polystyrene foams (XPS). Styrodur has a European market focus. Key benefits of the insulation board: Low water absorption through closed-cell content High compressive strength (300 kpa, 500 kpa, 700 kpa) 2

6 7 Challenge Challenge Maximum extruded board thickness was 200 mm German Energy Saving Ordinance (EnEV) partly requires greater thicknesses and better thermal conductivity Contactless thermal welding of thin boards to create a thick board Advantage: Better lambda values of the thinner boards are also valid for the welded board 8

7 Challenge Conventional process Welding Thickness (mm) Lambda (mw/mk) Remark: lower lambda better performance 9 10

8 Innovation The thermal welding of different building products offers new potential in the construction industry. Sound-absorbing elements Neopor is the enhancement of Styropor Excellent compressive strength outstanding lambda values 11 Innovation Partnership Status Quo BASF is currently examining potential synergies with selected partners 12
