Soft Rubber & Sealants Extruders

We have a long history of processing soft rubbers for sealants and adhesives

The Bonnot Company builds various designs for processing a variety of butyl and mastic rubbers.

Depending on the size and configuration you select, our equipment can accept soft rubber feedstock ranging from small pieces/ropes to full batches straight from your mixer. Often, the goal is to create a more manageable profile for downstream processing or creating various size strips feeding directly onto a roller/slitting equipment to create the final product.
