"J. Allcock & Sons are a supplier, recycler and manufacturer of materials to the polymer industries. We import and export throughout the world, spanning North America, South America, Europe, Africa and Asia.

Our two main areas of expertise are rubber and silicones. We have been manufacturing products for the rubber industry since our birth in 1924 and have been supplying silicones since 1973.

J. Allcock & Sons is a ISO 9001:2015 company. We believe we are probably one of the few if not only rubber recycler in the UK to achieve this accreditation.

Unlike J. Allcock & Sons, Wellington Rubber Company Ltd specializes completely in size reduction rubber recycling.

Company Philosophy:

We aim to provide problem free deliveries: The correct product at the right location on the date required, with goods correctly marked and accompanied by the required documentation. All we ask is a chance to prove ourselves.

We also recognize that price is important, so we aim to be competitive. All we ask in return it to be paid on the mutually agreed date.

We are happy to offer technical advice even if it does not generate immediate business for us. By offering such advice we hope that our customers will be able to trust implicitly what we have to say."

J. Allcock &amp; 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.
