AstroTurf is an American subsidiary of SportGroup that produces artificial turf for playing surfaces in sports. The original AstroTurf product was a short-pile synthetic turf invented in 1965 by Monsanto. Since the early 2000s, AstroTurf has marketed taller pile systems that use infill materials to better replicate natural turf. In 2016, AstroTurf became a subsidiary of German-based SportGroup, a family of sports surfacing companies, which itself is owned by the investment firm Equistone Partners Europe.
Avgas is an aviation fuel used in aircraft with spark-ignited internal combustion engines. Avgas is distinguished from conventional gasoline (petrol) used in motor vehicles, which is termed mogas in an aviation context. Unlike motor gasoline, which has been formulated without lead since the 1970s to allow the use of catalytic converters for pollution reduction, the most commonly used grades of avgas still contain tetraethyl lead, a toxic lead containing additive used to aid in lubrication of the engine, increase octane rating, and prevent engine knocking. There are ongoing efforts to reduce or eliminate the use of lead in aviation gasoline.

Artificial turf is a surface of synthetic fibers made to look like natural grass, used in sports arenas, residential lawns and commercial applications that traditionally use grass. It is much more durable than grass and easily maintained without irrigation or trimming, although periodic cleaning is required. Stadiums that are substantially covered and/or at high latitudes often use artificial turf, as they typically lack enough sunlight for photosynthesis and substitutes for solar radiation are prohibitively expensive and energy-intensive. Disadvantages include increased risk of injury especially when used in athletic competition, as well as health and environmental concerns about the petroleum and toxic chemicals used in its manufacture.
Polytan GmbH is a German manufacturer of synthetic turf systems and synthetic sport surfaces. It is based in Burgheim, Bavaria, and is a subsidiary of Sport Group Holding GmbH.
Crumb rubber is recycled rubber produced from automotive and truck scrap tires. During the recycling process, steel and tire cord (fluff) are removed, leaving tire rubber with a granular consistency. Continued processing with a granulator or cracker mill, possibly with the aid of cryogenics or by mechanical means, reduces the size of the particles further. The particles are sized and classified based on various criteria including color. The granulate is sized by passing through a screen, the size based on a dimension or mesh. Crumb rubber is often used in artificial turf as cushioning.

Astronics Max-Viz is an American company founded in Portland, Oregon on May 31, 2001 as Max-Viz, Inc. to design, manufacture and certify Enhanced Vision Systems ("EVS") primarily for use in the aerospace industry. Max-Viz EVS devices present real-time images of the external environment on aircraft cockpit monitors to improve pilot situational awareness under circumstances where visibility is impaired by weather or darkness. The company objective is to help the pilot see clearly and fly safely by providing visual information about where they are, where they are going and what is in their way. The Max-Viz EVS captures and enhances thermal infrared signals and can be combined with visible light as well as other electromagnetic energy sources. The company's systems are designed to be integrated with a variety of displays already in the aircraft cockpit.

Artificial turf is surface of synthetic fibers resembling natural grass. It is widely used for sports fields for being more hard-wearing and resistant than natural surfaces. Most use infills of crumb rubber from recycled tires; this use is controversial because of concerns that the tires contain carcinogens, though research into the issue is ongoing.
