Main Advantages of Liquid Silicone Rubber Sigma Mixer

High uniformity kneading structure: Dedicated ∑-shaped/customized low-shear paddle design ensures thorough LSR mixing without introducing excessive air.
Precise speed control: Low-speed, high-torque operation avoids localized overheating and performance fluctuations.
Excellent sealing system: Adaptable to low-viscosity liquid silicone rubber, preventing leakage and external contamination.
Strong vacuum degassing capacity: Effectively removers microbubbles generated during mixing, improving the appearance and physical properties of the finished product.
Stable temperature control: Jacketed structure supports cooling or constant temperature, ensuring system stability before vulcanization.
High batch consistency: Suitable for silicone rubber products with extremely high performance stability requirements.

Liquid silicone rubber (LSR) requires extremely high levels of uniformity in mixing, bubble control, and temperature stability. Compared to general mixing equipment, liquid silicone rubber sigma mixer is better suited to the characteristics of LSR processes in terms of paddle design, sealing structure, and vacuum control, which can effectively improve the consistency, reliability, and yield of the products.
