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.
