Sigma Mixer For Butyl Glue

Butyl glue has the following properties:

• Extremely high molecular weight
• Extremely high viscosity
• Strong elasticity
• High filler content (calcium carbonate, carbon black, etc.)

Butyl glue production process

Butyl glue is a high-viscosity, high-elasticity, and high-filler rubber system. It must be mixed with strong shear, strong extrusion, and high torque to achieve uniform plasticization. Sigma mixer is equipment designed for this material.

Why is sigma mixer suitable for producing butyl glue?

1. Double ∑-shaped blades provide strong shear force; the interlocking blades compress and tumble the material repeatedly, achieving:

• Uniform plasticization
• Thorough filler dispersion
• Improved adhesion

2. High torque at low speed:

• Suitable for high viscosity systems
• Stable output
• Not prone to overload

3. Butyl glue is typically operated at 120℃-180℃. Sigma mixer can be equipped with heating jacket to:

• Heat softens the rubber
• Reduces processing viscosity
• Improve mixing efficiency

4. Optional vacuum system for:

• Removing air bubbles
• Increasing density
• Improving sealing performance
