J. Allcock & Sons NBR Crumbs is made from the ambient grinding of vulcanized nitrile rubber waste material. This is obtained from a variety of sources.

J. Allcock & Sons EPDM Granules is produced by the ambient grinding of EPDM waste / scrap material. EPDM is a rubber made from either a co-polymer of ethylene and propylene – which will be peroxide cured, or a ter-polymer which has a small amount of an unsaturated polymer added – this will be sulfur cured. The two different types are rigorously segregated, both as scrap and as finished crumb (or granules).

J. Allcock & Sons FKM Crumbs is made by ambient grinding, using specialized machinery, of selected FKM waste. The machinery used enables much finer grades to be produced. Electron microscopy shows the miniscule particles to be “torn” rather than just “cut”. This ensures maximum combination with virgin compound and excellent retention of properties.
