Abstract
A fiber-reinforced thermoplastic composition includes a polypropylene polymer component including a low flow grade polypropylene and a high flow grade polypropylene, and a fiber reinforcement component. The fiber-reinforced thermoplastic composition is capable of being vacuum formed. In another aspect a thermoplastic composition includes a homopolymer component including polypropylene, a co-polymer component, an impact modifier, and one or more of a flame retardant component and a fiber reinforcement component. The thermoplastic composition is capable of being vacuum formed. The fiber-reinforced thermoplastic composition may be formed into an article such as an enclosure for an electrical component, and it may be chemically resistant to a medical grade cleaner.
