High-Performance TPE Compounds for Overmolding onto Dissimilar Engineering Plastics | TPE Material Grades | SEBS Compounds for Molding, Extrusion & Foaming | DING JI
The TOP-PELLET® High-Performance Overmolding Compound Series is specifically engineered to overcome the adhesion limitations of conventional TPE when bonded to highly polar engineering plastics. Through advanced compatibilizer technology and molecular-level interfacial graft modification, these compounds deliver exceptional melt-bonding performance. During two-shot injection molding and co-extrusion processes, they achieve outstanding chemical adhesion to a wide range of high-performance engineering substrates without the need for primers or additional surface treatments. This technology is specifically developed for challenging engineering plastics, including polyamide (PA6, PA66, and glass fiber-reinforced PA), polycarbonate (PC), ABS, PC/ABS, and ASA. The resulting overmolded interface exhibits seamless integration with outstanding peel strength, typically achieving cohesive failure rather than adhesive failure. Even under prolonged service conditions or severe thermal cycling, the bond remains highly resistant to delamination and separation. These materials are ideally suited for premium smart handheld devices, professional hand tools, automotive interior components, and precision medical device housings where superior tactile feel, structural integrity, and long-term bonding reliability are essential. Established in 2010, DING JI POLYMER CO., LTD. specializes in the development and manufacturing of TPE / TPR compounds. We provide custom formulation, material modification and mass production solutions for injection molding, extrusion, blow molding, foaming and specialty applications. With reliable quality management and OEM / ODM development capabilities, DING JI supports customers in industrial, automotive and consumer markets, serving as a trusted TPE compound manufacturer and material development partner worldwide.
