Laboratory Two-Roll Mills
The supplier:
Hapro
Hapro two-roll mills are used for laboratory preparation of polymer samples and for evaluating material behaviour under heat and shear.
The equipment is fitted with PLC control and a touchscreen. The roll speeds can be adjusted independently, allowing the processing conditions to be selected for a specific material and application.
HAPRO Two-Roll Mill Video Overview
Main Tasks:
- preparation of sheets and plaques;
- laboratory mixing of polymer compounds;
- evaluation of material behaviour during prolonged shear processing;
- preparation of samples for pressing and subsequent testing.
Applications:
For PVC, rubber and other polymer compounds, two-roll mills remain one of the core laboratory instruments. They help compare raw materials, formulations and material behaviour during heating.
