Best Application: Designed to measure dynamic and static properties of raw elastomers in all stages of a curing process.

Applications

The RPA Ultra is an unconventional closed cavity rheometer with a rotational lower die providing unrestricted oscillation strain and a frequency breakthrough of up to 100 Hz. The instrument is designed to measure dynamic and static properties of raw elastomers and rubber compounds in all stages of a curing process.

Another technology breakthrough is the extended range of shear rate going from 0.001 to 500 1/s. The high shear rate can be unutilized to simulate the extrusion process in a real production scenario. The UltraCurve can excel in measurement repeatability and reproducibility thanks to the unique engineering on the sealed biconical dies which can greatly reduce slippage during a testing process. The new Torontech software is a great complement to the UltraCurve making your testing process much easier to handle and results much more comprehensible.

Features/Advantages

BareissOne is a modularized software that is aimed to provide a common platform with integration of different test categories.

Whether it is a standard test for one single measurement or a series of tests that requires a complex test sequence editing, BareissOne is designed to offer all levels of user’s demands.

Features such as user authorization, system log, project management, version control and custom report are all at your fingertips.
