It helps bring incompatible polymers, such as PP and PE, together by forming them into a homogenous polymer mixture that increases mechanical properties based on polymer modification (link to full press release above).

The breadth of the materials includes Polystrand™ unidirectional tapes made with continuous glass fiber and an expanding variety of resins such as polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polyketone (PK), polyamide (PA), and others, and Fiber-Line™ engineered fiber tapes, made using uniquely processed fibers including carbon, glass, and aramid.

They can be injection molded or overmolded onto polypropylene (PP).

When overmolded, GLS TPEs bond permanently and virtually seamlessly to many different plastic substrates, including polypropylene (PP), polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), PC/ABS, copolyester, polyamide (nylon) and polystyrene (PS).

Polypropylene (PP) carriers are recommended for the harder SEBS formulations. PP carrier is not recommended for softer grades, as the formulation hardness will be affected.
