Overmolding PP

Overmoulding TPE grades designed for adhesion to polypropylene (PP) substrates deliver soft-touch feel, grip enhancement, and sealing functionality that pure PP cannot provide, while maintaining the recyclability advantage of an all-polyolefin material system.

Formulated with polymer blocks and compatibiliser systems selected for thermodynamic compatibility with PP, these grades enable direct molecular-level adhesion during overmoulding or co-extrusion — without primers, adhesives, or surface activation.

Peel strength to PP substrates consistently exceeds 4 N/mm under standard 180° peel test conditions, with cohesive failure mode confirming that the bond strength is not the limiting factor. Adhesion retention after thermal cycling (−40 °C to +80 °C) and humidity ageing (85 °C / 85% RH) is verified as standard.

Shore A hardness range covers 25A to 70A for grip, gasket, and sealing applications. Processing is compatible with standard PP injection moulding conditions (200–230 °C melt temperature).

Typical applications include tool grips, toothbrush handles, consumer electronics soft-touch overmoulds, and automotive interior trim where PP–TPE two-component design is specified.
