Overmoulding is a powerful technique that allows the production of finished parts in soft and hard material combinations without trimming or assembly.

It offers many design and product advantages, allowing designers to differentiate products while meeting important user and patient demands, including soft-touch and cushioning for greater comfort and non-slip surfaces with improved grip for safety.

Adhesion to a variety of substrates
The standard Mediprene® series bonds very well to polyole? ns like polyethylene (PE) and polypropylene (PP). However, in several medical applications transparent engineering plastics like ABS, PC, PETG and SMMA (and their blends) are utilised. The Mediprene® A2 series has been developed to address demands for medical grade TPEs that bond well to these substrates.

Regulatory compliance
Representative Mediprene® grades have passed cytotoxicity tests according to ISO 10993-5 and are compliant with USP Class VI.
Mediprene® TPE materials are PVC, silicone and latex free, making them allergen free and a viable alternative to PVC based compounds.

Applications
Potential applications for the Mediprene® A series include; seals, membranes, closures, friction grips, soft-touch handles.
Mediprene® TPEs provide enhanced sealing capabilities in fluid environments.
