Capillary Rheometer for Polymer Compound Melt Viscosity

Twin-barrel capillary rheometer that measures shear viscosity of molten polymer compounds across a range of shear rates. Used by compounders to qualify processing behaviour of filled and reinforced resins.

Specification

A piston forces melt through a capillary die at programmed speeds while pressure transducers record the force. Viscosity curves guide extrusion and molding settings for each compound. Bagley and Rabinowitsch corrections are built into the software.

Features

• Barrel temperature to 450 deg C
• Programmable piston speed
• Pressure transducers 0 to 100 MPa
• Interchangeable dies L/D 10 and 20
• PC software with viscosity curves
