Sigma blade mixer is widely utilized for the kneading and mixing of raw rubber, compounded rubber, liquid silicone rubber, molding compounds and sealants. Featuring a unique ∑-shaped blade design, it generate intenses shear forces and folding effects under high-viscosity conditions, ensuring the perfect fusion of fillers and polymers.
Key Advantages of Silicone Rubber Sigma Blade Mixer
- Vacuum degassing system: Achieves an ultimate vacuum level of -0.098MPa, effectively eliminating air bubbles and low-molecular-weight volatiles from the compound to enhance the transparency and electrical insulation properties of the finished product.
- Precise temperature control: Supports circulation heaitng via thermal oil or water cooling, offering temperature control accuracy of up to ±1℃ to prevent thermal degradation or premature vulcanization of silicone rubber during the kneading process.
- Zero-contamination sealing technology: Employs a combination of multiple mechanical seals and Teflon packing to completely prevent lubricant infiltration into the compound, thereby meeting the stringent purity requirements for medical-grade and electronic-grade silicone.
- High-efficiency ∑-shaped blades: Features a differential speed ratio optimized through fluid dynamics to eliminate mixing dead zones, shortening the mixing cycle by 20-30% compared to traditional equipment.

Silicone Rubber Sigma Blade Mixer Design Highlights
- Screw extrusion: offers flexible discharge solutions tailored to silicone rubbers of varying viscosities. The screw-extrusion model can be directly integrated with granulators or rubber strainers.
- Wear-resistant materials: All components in contact with the material are constructed from SS304/316. The surfaces undergo mirror polishing to ensure high hardness, corrosion resistance, and ease of cleaning.
- Intelligent PLC control: Enables real-time monitoring of rotation speed, temperature, current and vacuum levels. Supports one-touch recall of multiple stored recipes, as well as encrypted storage of recipe data.
Applications of Silicone Rubber Sigma Blade Mixer
- Solid silicone rubber (HTV): Compounding and coloring of rubber compounds across various hardness levels.
- Liquid silicone rubber (LSR): Medical components, baby products, electronic encapsulants.
- Room temperature vulcanizing (RTV) silicone rubber: Construction sealant, mold-making compounds.
