CREATING TOMORROW’S SOLUTIONS SOLID AND LIQUID SILICONE RUBBER IN BRIEF EL ASTOSIL ® SILICONE RUBBER: NATURALLY VERSATILE 2 SILICONE EL ASTOMERS AND THEIR SPECIAL PROPERTIES Silicone rubber differs from other elastomers in its unparalleled property range. Of particular interest are the characteristics resulting not from additives or surface treatment, but from the polymer and filler structure. These are inherent properties of WACKER’s rubber. ELASTOSIL®, LUMISIL®, SILPURAN ® and SILMIX® are registered trademarks of Wacker Chemie AG. ELASTOSIL® silicone rubber withstands continuous high temperatures and dynamic stress, and thus represents the perfect solution for turbocharger hoses All ELASTOSIL® silicone rubber grades have good mechanical properties. Specialty grades have very high tear resistance, making them ideal for bottle nipples and pacifiers Typical Properties ELASTOSIL® silicone rubber is extremely resistant to high and low temperatures (-50 °C to +250 °C; specialty grades: -110 °C to +300 °C) with only slight changes in physical properties between -50 °C and +180 °C. The rubber’s other typical properties include its resistance to chemicals and environmental influences, its lack of odor and taste (many grades conform to BfR and FDA regulations), its water-repellent surface, and its high transparency and good processability. Many other properties can be modified with additives. At a Glance • Outstanding low-temperature flexibility and high-temperature resistance •Excellent compression set •High resistance to chemicals and environmental influences •Water-repellent surface •High transparency; can be pigmented as desired •Good mechanical properties •G ood flame resistance; non-toxic combustion products in the case of fire •Odorless and tasteless •Can be easily processed •Can be adjusted electrically from insulating to semiconducting •High radiation resistance 3 SOLID SILICONE RUBBER EL ASTOSIL ® R AND EL ASTOSIL ® R PLUS Solid silicone rubber bar (standard supply form) Extrusion of ELASTOSIL® solid silicone rubber WACKER offers two product ranges based on solid silicone rubber: A line of peroxide-curing grades marketed as ELASTOSIL® R and a line of addition-curing (platinum-catalyzed) grades marketed as ELASTOSIL® R plus. You can choose between our ready-to-use blends or our basic rubber. Our product offering is rounded out by crosslinkers, stabilizers, colorants and other additives. Supply Forms The standard delivery form is as bars measuring 90 x 100 mm (crosssection), which are wrapped in PE film and shipped in cartons. For special requirements, we also offer our readyto-use blends in the form of strips, round-cords, pellets and profile strips. 4 Processing ELASTOSIL® solid silicone rubber can be processed using the standard methods, e. g. extrusion, molding (injection, transfer or compression molding) and calendering. Customized Compounds Under our SILMIX® trademark, we develop, compound and produce customized, ready-to-use blends for you at our sites around the world – always maintaining our high WACKER quality standards. LIQUID SILICONE RUBBER EL ASTOSIL ® LR Demolding an injection-molded sheet from the mold ELASTOSIL® liquid silicone rubber is supplied in drums (A and B components) At WACKER, we market liquid silicone rubber grades as ELASTOSIL® LR (LR = Liquid Rubber). These twocomponent, addition-curing (platinumcatalyzed), pumpable rubbers can be injection molded and cured at high temperatures and very short cycle times. Supply Forms The A1 and B2 components are delivered in 20-kg or 200-kg containers: • 20-kg pails with a PE inliner (inside ø 280 mm) • 200-kg drums with a PE inliner (inside ø 571.5 mm) Multicomponent Parts You can use our self-adhesive grades to produce multicomponent parts by 2K injection molding, e.g. hard-soft or softsoft combinations (color combinations or combinations of grades with different hardnesses). Processing ELASTOSIL® LR liquid silicone rubber is processed by injection molding, which allows for complex part geometries, precise dimensions and fully automatic production, without the need for secondary finishing. Colors Additionally, we supply colors whose viscosity matches that of our silicone rubber grades. 1 Contains platinum catalyst 2 Contains crosslinker 5 IMPORTANT APPLICATIONS OF SILICONE RUBBER
