Abstract: A surgical article formed from a fiber-reinforced thermoplastic composition includes a polypropylene polymer component and a fiber reinforcement component. The surgical article is formed using a vacuum forming process. The surgical article may include a surgical tray including a bottom surface having side walls disposed around a periphery thereof and extending from the bottom surface. The vacuum forming may include a heater profile configured to heat a surface area at a perimeter of a plaque such that a plaque thinning at the bottom surface is minimized and radius stretch through the side walls is minimized, thereby retaining maximum wall thickness.

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.

Abstract: A method of making an article includes: heating a plaque formed from a thermoplastic composition; and vacuum forming the heated plaque to form the article. The thermoplastic composition includes a polypropylene polymer component and a fiber reinforcement component. The heating is implemented using one or more heaters having a maximum temperature output of between 1500-3000° C. and maximum intensity between 0.80 μm and 2 μm. The article may include a surgical tray having a bottom surface having side walls disposed around a periphery thereof and extending from the bottom surface.
