How to choose the appropriate rotor of torque rheometer

Rotor is the core component of torque rheometer test. There are many types of rotor, mainly introduced below five common rotors and their applicable materials.

Rotor is the core component of torque rheometer test. There are many types of rotor, mainly introduced below five common rotors and their applicable materials.

 

1. The Roller rotor

Suitable for the mixing of thermoplastics, thermosetting plastics, it can test the viscosity, crosslinking reaction and shear / thermal stress of materials.



2. The Cam rotor

Mix and test thermoplastics and rubber in the medium shear range.

 

3. The Banbury rotor

For mixing and testing of natural rubber, synthetic rubber and mixing rubber.

 

4. The Sigma rotor

Mix the powder within the low shear range to test the mixing performance.

 

5. Delta rotor

Mix of thermosetting materials is crosslinked using a Type 540 cone compact chamber.
