For realistic laboratory simulation

C.W. Brabender mixing bowls and removable blades are cast of 304 Stainless Steel. Custom metallic and heat hardened surfaces are available upon request. A torque overload shear coupling is attached to each mixer, protecting the motor drives from torque overload and preventing damage to the Mixer/Measuring Head.

Roller Blades are most commonly used for materials that require a strong shear force to form a homogenous melt: thermoplastics, and many thermosetting resins such as phenolics and expoxies. Typical studies: fusion, lubricity, heat stability, crosslinking, and degradation.

Banbury Blades are desigened to duplicate the mixing action of a commercial Banbury Mixer... a medium shear-rate mixing action ideal for mixing elastomeric materials, compounding studies, and recycled materials.

CAM Blades have achieved widespread success in the Rubber Industry... a medium shear-rate blade imposing a combination of milling, mixing, and shearing forces against the test sample, alternating compacting and releasing the material within the chamber.
