Overmolding TPE | Adhesion to PP, ABS, PC/ABS, PA
Overmolding TPE Resin – Overview & Applications
TPE-S overmolding compounds (SEBS- and SBS-based) with adhesion to PP, ABS, PC/ABS and PA substrates.
Chemdo supplies overmolding TPE designed for 2-shot molding and insert overmolding on common engineering plastics.
Our portfolio covers adhesion to PP, ABS, PC/ABS and PA6/PA66, with Shore A hardness from 30–90.
These grades are used for soft-touch grips, handles, buttons, edge protection and anti-slip areas in tools, personal care, electronics, appliances and industrial products.
Chemdo offers both SEBS-based and SBS-based overmolding TPE systems,
covering high-performance bonding on PC/ABS and PA substrates as well as cost-efficient grip solutions on PP and ABS consumer products.
This allows customers to balance performance, durability and cost according to their project.
