The substrates materials employed for overmolding were PP, ABS, PC/ABS, polyester, Nylon and POM. Each formulation was designed to selectively bond to a substrate based on the functionality of the substrate material. The bonding characteristics of TPE-2 materials to all the substrates were adhesive in nature.

The TPE family has adhesion on any type of polyamide tested in the study, including undried materials, making them truly Universal polyamide overmold TPEs. Novel developments in thermoplastic elastomers have been driven by application demands that far exceed the TPE chemistry material selection Page 1 of 11 space illustrated in this figure. The current paper offers a novel robust TPE material selection for overmolding on to Polyamide.

This is especially true for long, thin parts or parts where the substrate is thinner than the over-mold or if a low modulus substrate material is used. This can be partially counteracted by using higher modulus substrate materials and providing stiffening ribs in the substrate. Provide a spring-loaded area if the inserted substrate is metal or other non- compressible material.

If a reinforced substrate material is used a high hardness abrasion resistant steel may be required. Part dimensions including substrate warpage. Back gating through a pin and hole in substrate

Fluoropolymers typically have non-stick properties that make it difficult for ink to adhere to the substrate. When the material is cured properly, the print will melt into the top layer of the surface of an application. The use of the same matrix material creates a uniformly melted top layer.

Hardness is defined as a materials’ resistance to indenture. For over-mold applications, the thinner the elastomer is on the substrate, the harder it will feel. One of the controlling factors for relative hardness is a function of both the substrate and the TPE thickness.
