In addition to this is a raft of highly successful intercompany and academic research work has been completed which has benefited customers by providing highly bespoke and specialised polymer solutions. These important links forged between academia and industry is the key to providing the very best solutions available on the market to our customer base.

Handling complex materials & solutions

The role of an additive masterbatcher is to transform a range of materials which may have different physical states at room temperature, incompatibility with polymer or other components and produce a homogenous uniform pellet.

This allows the end user to receive all the benefits of those materials in a preformulated recipe, removing any difficulty or inconsistency of the dosing. Wells removes the need for the processor to handle liquids, powders and flakes, providing a high-quality single pellet solution with the functionality needed.

Based in the UK & working across the Globe

Wells products reach a truly international customer base from the Americas through to the Far East. With an extremely strong presence in the UK and Europe serving a range of clients from polymer producers through to medical device manufactures Wells products are service are established within the industry.
