Rubber Testing

D-RPA Dynamic Rubber Process Analyser

The MonTech D-RPA 3000 is designed for measuring the viscoelastic properties of polymers and elastomeric compounds before, during and after cure. The acquired data gives exact information about the processability, cure characteristics, cure speed, and behaviour of the compound at the after-cure.

The D-RPA 3000 fulfils the complete range of all test requirements; Polymers, raw materials, basic, finished and cured compounds can all be characterised. Besides the cure properties, cure characteristics and processability can all be determined and evaluated.

The D-RPA 3000 is the state-of-the-art machine for dynamic testing purposes. The machine can be fitted with several unique options such as variable die gap, low-temperature cooling, and high speed data acquisition – providing the highest frequency-strain combination available on the market.

The high flexibility of the D-RPA 3000 allows the user to program and execute arbitrary test sequences with the MonControl Analyses Software. Each dynamic test sequence can include an unlimited number of the following substeps: timed tests, isothermal tests, non-isothermal tests, amplitude sweeps, frequency sweeps, temperature sweeps, shear rate sweeps, relaxations, retardations, hysteresis and tension tests. Of course, any combination of these sub-tests are possible – with or without an initial strain, as well as strain or stress controlled.

Equipped with single test – multi sub-test test procedure programming with up to 1000 sub-programs as well as an unbeaten shear rate range of up to 100 sec-1 – the D-RPA 3000 is truly the most flexible and dynamic multi function Rheometer in the market.

Completely closed, directly heated, biconical test chamber system
entirely made of high-strength stainless steel, precision ground and hardened, significantly reducing sample slippage for highest dynamic test ranges and most accurate torque, modulus and viscosity readings.

Automation options
All MonTech Moving Die Rheometers as well as Rubber Process Analysers can be easily automated, allowing customers to increase productivity and release operators for other important tasks.

MonTech offers the worlds largest Rheometer Automation portfolio designed for our customers to rely on – in the lab or on the shop floor, in multiple shifts, 365 days, every year. Depending on the selected type of automation system, samples are loaded and unloaded automatically from linear or rotary trays, film is fed and tested samples are removed automatically.

Of course, every automated machine can – within a single click – also be switched into manual operation mode.
