Model GXR™ (Double-Roof Disk Static Mixer)

The GXR™ Static Mixer (Licensee of Bayer, AG) is used for mixing, dispersing and homogenization of viscous materials. It is a high performance motionless mixer design that creates a very high degree of mixing in a short length. It is capable of mixing materials with very large differences in viscosity and volumetric ratios.

Mixing Capabilities

Mix fluids with similar viscosity
Mix high and low viscosity fluids (viscosity ratios up to 1,000,000:1)
Mix fluids with large differences in volumetric ratio (volumetric ratios up to 10,000:1)
Disperse and mix polymers with blowing agents
Thermal homogenization
Viscosity homogenization

Applications

Two (2) component viscous materials such as Liquid Silicone Rubber (LSR), adhesives, polysulfide, sealants, epoxy resins, polyurethanes, etc.
Plastics Injection Molding
Plastics Extrusion
Polymer manufacture and processing
The mixing elements may be safely pressed out of the housing by pushing on the support ring which avoids any damage to the mixing grid.

The GXR™ mixing elements are also available in inexpensive plastic construction (50% glass-filled Nylon and polypropylene)
