Exploring Butyl/Mastic Rubber Extruders
The Bonnot Company has manufactured a line of extruders for processing butyl/mastic rubbers (butyl) since the 1950's. The company recognized the need to offer processing extruders for this rapidly developing market. In keeping with a core principle of continuous improvement, these designs have evolved over time to remain the pre-eminent industry choice for butyl processing equipment/extruders.

Bulk Feeding Solutions with Custom Extruders
The Bonnot Company has a variety of custom extruders designed for bulk feeding of rubbers, both natural and synthetic, silicones, butyls and mastics. Regardless of the batch size or material viscosity, there is a solution available. If one of the company's standard designs does not meet your needs, a custom solution is developed. Customized solutions specifically tailored to a customer's needs are a core competency of ours and competitive advantage.

Why Bonnot is #1 Globally for Catalyst Extrusion
It's no secret that Bonnot has been around a long time. We're so old, in fact, that we don't have Articles of Incorporation — they weren't necessary in 1891. But what most people don't know is that we started out making machines to process clay. By the early 20th century we transitioned to brick machines, paving roads for cities across the US, and eventually to the wide catalog of extrusion equipment and machines we're known for around the world today.

Replace Your Old Rubber Granulator with a Bonnot Rubber Bale Feeder
Rubber granulators have been used for over half a century to resize rubber bales into usable chunks for downstream processing. They are designed to run for many years, which is why they're still prominently used in rubber processing plants. The problem with rubber bale granulators is that they often require the introduction of chemical agents to do that job efficiently. Luckily, Bonnot has the solution — and we have for more than 25 years.
