OverviewSigma mixer specifically designed for mixing high-viscosity organic silicone rubber. JCT Machinery offers equipment selection and turnkey solutions based on silicone formulations and production capacity targets. Applicable silicone types include HTV, RTV-1/RTV-2, HCR and LSR.
Product detailsThe organic silicone rubber sigma mixer is core mixing equipment engineered for high-viscosity, high-elasticity silicone compounds. It is widely used for HTV, RTV, HCR, LSR, masterbatch and color compounds. The machine uses dual ∑-shaped mixing paddles to provide intensive shearing and tumbling action for uniform dispersion of base polymer, fillers and additives.
Applicable materials- High-temperature vulcanizing silicone rubber (HTV)
- Room-temperature vulcanizing silicone (RTV-1/RTV-2)
- Liquid silicone rubber (LSR)
- Silicone masterbatch and color compounds
- Silicone systems with high filler content
