Complēt™ & Onforce™ Long Fiber Reinforced Thermoplastics are formulated for demanding applications that require high stiffness and good impact in structural and metal replacement applications. These tapes and laminates combined high strength, unidirectional fibers and engineered thermoplastic resins to help reduce weight while maintaining exceptional strength and impact resistance. The campaign was designed to engage people in local impact in order to have a global impact.

Rigid substrates include polypropylene(PP), polyethylene (PE), amorphous polar plastics such as polycarbonate (PC), polymethylmethacrylate (PMMA), polystyrene (PS), high impact polystyrene(HIPS), polyphenylene oxide (PPO), glycol modified polyethylene terephthalate (PETG), Acrylonitrile Butadiene Styrene (ABS), semicrystalline polar plastics such as polyester (PET, PBT) and Polyamide (Nylon 6, Nylon 66). Depending on the wall thickness of the elastomer and the substrate, the production rate can be very high. They include amorphous polymers such as polystyrene (PS), High Impact Polystyrene (HIPS), Polycarbonate (PC), Acetal (POM), PC/ABS, Acrylonitrile Butadiene Styrene (ABS), Polyphenylene oxide (PPO), Noryl® (a miscible blend of PS and PPO), and PC/PETG.
