Silicone Rubber Mixer | JCT Machinery

Sigma mixer plays a vital role in the efficient and consistent production of high-quality silicone rubber compounds.

Key Features of Sigma Mixer for Silicone Rubber

1. Kneading Action

• Sigma mixer is known for its kneading action, which is crucial for achieving uniform dispersion of ingredients in silicone rubber compounds.
• The blades of sigma mixer rotate in a ∑-shaped pattern, creating a shearing and kneading effect that ensures thorough mixing.

2. High Viscosity Handling

• Silicone rubber compounds often have high viscosities, and sigma mixer is designed to handle such materials effectively.
• The robust construction and powerful motor of sigma mixer allow it to process and knead high viscosity silicone rubber formulations.

3. Temperature Control

• Many sigma mixers used in silicone rubber manufacturing come equipped with features for temperature control.
• Heating or cooling jackets can be incorporated during the mixing process, expecially when dealing with heat-sensitive formulations.

4. Uniform Dispersion of Fillers

• Silicone rubber formulations often include fillers and sigma mixer excels at achieving uniform dispersion of fillers throughout the rubber matrix.
• The kneading action of sigma blades ensures that fillers are evenly distributed, contributing to the mechanical properties of the final product.

5. Batch Processing

• Sigma mixer is generally used for batch processing, making them suitable for small to medium-scale silicone rubber production.
• The batch processing capability allows for precise control over the mixing parameters and ensures consistency in the final product.

6. Easy Cleaning and Maintenance

• Sigma mixer is designed for easy cleaning between batches, minimizing the risk of cross-contamination.
• Regular maintenance routines can be performed to keep the equipment in optimal working condition.
