Our TPVs can be combined with compatible polymers through several types of multi-shot injection molding processes. By combining multiple materials, an ever wider variety of part applications can be achieved.
Two-shot molding requires that the two materials be compatible (chemically similar), or no bonding occurs. Standard grades of Santoprene TPV and Vyram TPV bond to polypropylene, some polyethylenes and some TPOs. Nylon-bondable (PA series) grades bond to nylon-6 with a variety of fillers and to some blends of nylon 6/6 (2-shot molding only). Specialty grades also exist that bond to ABS, polycarbonate and polystyrene.
