Not all GLS™ TPEs will bond to all types of substrates; for example, a Dynaflex™ TPE that bonds to polypropylene (PP) will not adhere to polycarbonate (PC). The most common color concentrate carrier is PP because it is compatible with many commercially available TPE products (for both single component molding and overmolding PP applications).
