“Product requirements on plastic and rubber materials have risen drastically over recent years. Some standard materials can no longer keep pace with this development,” said Christian Gimber at today’s K 2019 Preview press conference in Düsseldorf. “That is why more and more companies are counting on silicone elastomers. Thanks to their outstanding mechanical and chemical properties, silicones have become indispensable for solving demanding technical problems and developing and implementing innovative technologies.”
This year, WACKER’s booth will cover eight topics. One of these will focus on the advantages of liquid silicone rubber that contains very few volatile components. Since early 2019, this applies to ELASTOSIL® LR 3xxx, ELASTOSIL® LR 6xxx and SILPURAN® 6xxx silicones manufactured in Europe. Thanks to ultra-modern process technologies, WACKER has managed to slash the content of volatile Dx siloxanes in its liquid silicone rubber by at least 90 percent. By upgrading the LSR portfolio in this way, the company is enabling manufacturers of silicone parts to meet regulatory requirements and industry as well as customer needs more readily and reliably than ever before. WACKER’s initiative is setting new industrial standards worldwide.
The ELASTOSIL® LR 5040 product line shows what is possible and what advantages the new standard offers. These high-performance silicones cure to form elastomers that possess the same mechanical properties without thermal treatment as a product that has been post-cured. Users can skip the lengthy and costly process step of post-curing altogether. Due to their high purity, parts made of ELASTOSIL® LR 5040 are suitable for food-contact applications and can be used in line with the recommendations of the German Federal Institute for Risk Assessment (BfR) and the US Food and Drug Administration (FDA). They also meet the criteria of selected bio-compatibility tests in ISO 10993 and US Pharmacopeia (Class VI).
ELASTOSIL® LR 5040 will also be at the center of this year’s injection-molding demonstration at the WACKER booth. Here, food-contact parts will be produced out of the liquid silicone rubber during the tradeshow. A HoloLens will furthermore offer virtual insights into the technology and functions of the injection-molding machine provided by Krauss Maffei (tool: ACH Solution).
