The Basics

What is bound rubber?

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.

Performance Optimization

A better way to test bound rubber

The Premier Rubber Process Analyzer delivers faster, more accurate bound rubber results, with automated, high-throughput testing that improves compound formulation decisions.

Faster, more repeatable testing

Cuts testing time from 72 hours to minutes, improves repeatability and eliminates human error.

Reduced heat build-up

Cyclic strain sweeps quantify energy loss, helping you optimize filler-polymer interactions to control heat generation in real-world use.

Better formulation decisions

Simulate diverse conditions, including sub-ambient temperatures, to optimize compound resilience.

About the Premier RPA

Bound rubber effects in minutes, not days

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.
