1. Difficulty in stirring during the high-viscosity stage
During the middle and late stages of the silicone resin polycondensation reaction, the system viscosity can exceed 1,000,000cps, making the reactor's agitator impeding the material.
2. Strong shear and stirring are required
Sigma mixer's double ∑-shaped blades provide strong shear and squeezing forces, ensuring uniform heating and reaction of high-viscosity silicone resins.
3. Facilitates vacuum dehydration and complete polycondensation
Simga mixer, equipped with a vacuum system, efficiently removes water at low temperatures, promoting complete polycondensation and improving resin purity adn stability.
4. Combines mixing and concentration
Many silicone resin formulas require concentration or the addition of fillers (such as silica or alumina powder) in the later stages. Sigma mixer can accomplish this in one machine.
