The silicone materials involved can be processed with roughly the same ease as compounds like epoxide-based or polyurethane-based resins
The new silicone resin binders, which are not subject to labeling requirements under EU directives, offer several advantages and are therefore an alternative to high-temperature-resistant polymers like PTFE (polytetrafluoroethylene) and PEEK (polyether ether ketone).
Components produced using these new products are hallmarked by good mechanical strength and UV stability. The silicone materials involved can be processed with roughly the same ease as compounds like epoxide-based or polyurethane-based resins, which are very commonly used for producing components subject to lower levels of thermal stress.
SILRES LR 700 and POWERSIL Resin 700, both solvent-free phenyl methyl silicone resin binders, are transparent, low-viscosity liquids. Both binders require suitable combinations of fillers when processed into molded parts with good mechanical properties.
Wacker has therefore developed an optimized formulation called POWERSIL® Resin 710. This means that the company has two alternatives on the market for manufacturing molded parts that are stable at high temperatures: customers who prefer to work with their own fillers and/or filler blends, can use SILRES LR 700 and POWERSIL Resin 700 liquid binders; the best pick for users who want to take advantage of ready-to-use solutions, is POWERSIL Resin 710. The formulation comprises the silicone resin binder and a filler blend consisting of powdered and fibrous fillers.
