There’s a way to achieve both form and function by adding a soft-touch, thermoplastic elastomer (TPE) grip. But by adding a TPE grip to an outdoor product, the perceived value and selling price skyrockets. Some TPE formulas produce a more secure grip, or you can make use of a custom texture for improved handling.

These are high clarity TPEs with high tensile and tear properties. These TPEs have good processability. Ingredient selection for the TPE compound required a careful match of refractive indexes.

TPE-2 TPE-2 materials are opaque and their base chemistries are different from TPE-1. Figure 3 shows the capillary viscosity of TPE-1 and TPE-2 at 200oC. These results confirm that TPE-1 and TPE-2B are truly the “universal overmolding TPEs.”

Overmolding TPE compounds have a relatively low viscosity. ADHESION MEASUREMENT OF THE OVERMOLD TPE The bond strength between the TPE and the engineering plastic can be measured by performing a “90° Peel Test”. NOVEL TPE DEVELOPMENTS: Non-Drying TPEs for PC, ABS, PBT and their alloys Novel classes of non-drying TPEs which can overmold onto a variety of engineering thermoplastics have been developed.
