Sigma Kneader Mixers for Polymers and Elastomers

Mixing solutions for high- and very high-viscosity materials

The elastomer, polymer and silicone industries use raw materials whose rheological properties are among the most complex to manage. High viscosities, heavily filled formulations, thermomechanical behaviour, filler dispersion, the incorporation of additives and shear control are all parameters that directly influence the quality of the final product.

RMC Marc Guittard has been supporting manufacturers specialising in the processing of rubbers, silicones, polymers and engineering resins for many years. Drawing on its expertise in the mixing of high- and very high-viscosity products, the company designs, manufactures, refurbishes and reconditions Z-arm mixers that are perfectly suited to the demands of these industrial processes.

Our solutions ensure a homogeneous mixture, excellent dispersion of components and perfect reproducibility of formulations, from laboratory trials through to industrial production.

Expertise in polymer and elastomer mixing processes

The formulations used in these industries require precise control of numerous parameters in order to guarantee the mechanical, chemical and functional properties of the materials.

Each project is analysed in terms of:

  • the viscosity of the mixture,
  • the dispersion of mineral fillers or pigments,
  • the incorporation of additives,
  • the thermomechanical behaviour of the materials,
  • the required shear rate,
  • vacuum operation,
  • heating or cooling temperatures,
  • production rates,
  • cleaning and maintenance requirements.

 

This approach enables the design of equipment perfectly suited to the manufacturing constraints of each manufacturer.

Solutions tailored to a wide range of applications

Natural and synthetic rubbers

RMC Marc Guittard Z-arm mixers are used to mix numerous families of rubbers intended for industrial use:

  • butyl rubber,
  • compounds,
  • technical elastomers.

 

These applications require equipment capable of generating high torque to ensure the formulations are thoroughly homogenised, even when high fillers are present.

Silicones and RTV/HTV applications

Silicone-based formulations have specific requirements in terms of temperature control, shear and dispersion.

Our equipment is suitable for the manufacture of:

  • silicone bases,
  • silicone compounds,
  • RTV (Room Temperature Vulcanising) silicones,
  • HTV (High Temperature Vulcanising) silicones.

This expertise guarantees consistent formulation quality whilst preserving the mechanical and chemical properties of the materials.

Polymers, plastics and resins

RMC Marc Guittard supports manufacturers in the processing of a wide range of polymeric materials, including:

  • engineering polymers,
  • plastics,
  • polyester resins,
  • epoxy resins,
  • urethane.

Mixing parameters are optimised to ensure excellent dispersion of fillers, perfect homogeneity and optimum stability of formulations.

Engineering fillers and mineral materials

Highly filled formulations require particularly robust equipment capable of ensuring homogeneous mixing whilst minimising wear on components.

Our solutions are used for processing:

  • carbon pastes,
  • clays,
  • mineral fillers,
  • high-viscosity engineering formulations.

Creative and technical materials

RMC mixers also meet the manufacturing requirements for specific products such as:

  • paper pulp,
  • modelling clay.

These applications require excellent homogeneity of the mixture to guarantee the mechanical properties and performance of the finished products.

 

Equipment designed for the most demanding applications

The mixers developed by RMC Marc Guittard are designed to cope with the challenges posed by highly viscous, abrasive or filled materials.

Each piece of equipment is specified according to:

  • the rheological characteristics of the materials,
  • the torque required for mixing,
  • operating temperatures,
  • vacuum operation,
  • construction materials suitable for abrasive or corrosive products,
  • production capacities,
  • maintenance and operational requirements.

This approach ensures that the equipment is robust, reliable and perfectly suited to the most complex industrial processes.

 

From formulation to industrial production

The RMC Marc Guittard teams support their clients right from the earliest stages of development: laboratory testing, process validation, bespoke design, manufacturing, installation, commissioning, maintenance and modernisation of equipment.

This expertise enables the long-term optimisation of plant performance whilst safeguarding industrial investments.
