We have a custom built mixing plant on the same site as our press shop with a Shaw Intermix K4 (MK5) internal mixer, 18” & 60” mill, Baker Perkins lab batch mixer and bale cutters. In addition to this we have a full digital, coded scale system which allows us full batch traceability on everything we produce.
Some of our common compounds can be found by downloading the 'Specific Polymers' link, but should you wish to discuss a custom compound please feel free to contact one of our sales engineers at sales@bovill-boyd.co.uk.
