Overmolding Solutions

There are a variety of PolyOne TPEs designed to have excellent adhesion to a number of rigid plastic substrates for overmolding. The page below summarizes the common overmolding situations for medical, universal, polypropylene, polyethylene, polystyrene, polycarbonate, acrylonitrile butadiene styrene, nylon and copolyester.

If you do not see your substrate in this page, please contact us directly; we can develop a custom overmolding TPE that is optimized to bond to your specific substrate.
