With the help of the silicone resins from WACKER, molded parts can be pressed, pressure gelled or even injection molded.

The industry is increasingly faced with the challenging task of producing mechanically resilient plastic components that can permanently withstand temperatures above 200 degrees Celsius. WACKER has developed a novel material solution for this purpose, which will be presented for the first time at the K 2022 International Trade Fair for Plastics and Rubber in Düsseldorf from October 19 to 26. With the help of the silicone resin binders SILRES® LR 700 or POWERSIL® Resin 700 and the silicone molding material POWERSIL® Resin 710 based on it, molded parts can be pressed, pressure gelled or even injection molded. The product is therefore suitable for molded parts of heat class R, which must permanently withstand temperatures of up to 220°C.

 

The new silicone resin binders, which do not require labelling, are an advantageous alternative to high-temperature-resistant polymers such as PTFE (polytetrafluoroethylene) and PEEK (polyetheretherketone). Components manufactured using the new products are characterized by good mechanical strength and UV stability. The silicone materials can be processed as easily as polyurethane or epoxy resins, for example, which are widely used in the production of thermally less stressed components.

The solvent-free phenyl-methyl silicone resin binders SILRES® LR 700 and POWERSIL® Resin 700 are low-viscosity, clear liquids. In order to be able to produce molded parts with good mechanical properties from the binders, suitable filler combinations are required. WACKER has therefore also developed a first correspondingly optimized formulation: POWERSIL® Resin 710. The company thus offers the market two alternatives to the production of high-temperature-stable molded parts: for customers who want to work with their own fillers or filler mixtures, the liquid binders SILRES® LR 700 or POWERSIL® Resin 700; and for users who want to rely on ready-to-use solutions, POWERSIL® Resin 710, which consists of the silicone resin binder and is filled with a mixture of powder and fibrous fillers.

 

With its innovation, WACKER is responding to the industry's increasing demand for high-temperature-resistant polymers. Because technical systems are constantly becoming more powerful and at the same time smaller, they release more heat per unit area. An example of this is provided by electric motors in electric cars. Power losses of five watts per cubic centimeter are not uncommon here. Electrically insulating, polymeric components that are located near such heat sources should perform their function flawlessly for several years and must maintain their properties at the high temperatures that occur.
