Bound rubber is the part of a rubber compound that sticks to filler particles and doesn’t dissolve in solvents. It’s a key indicator of how well fillers are dispersed and how strong the rubber-filler interaction is.
Despite its value, standard methods of measuring bound rubber are inefficient and unreliable, which is not ideal in a fast-paced industrial R&D or quality control lab.
The Premier Rubber Process Analyzer delivers faster, more accurate bound rubber results, with automated, high-throughput testing that improves compound formulation decisions.
Cuts testing time from 72 hours to minutes, improves repeatability and eliminates human error.
Cyclic strain sweeps quantify energy loss, helping you optimize filler-polymer interactions to control heat generation in real-world use.
Simulate diverse conditions, including sub-ambient temperatures, to optimize compound resilience.
The Premier RPA is a dynamic mechanical rheology instrument designed for rubber compounds. Its strain sweep testing characterizes bound rubber effects in minutes, replacing solvent extraction methods that take about 72 hours.
