Polystyrene[Polystyrene?:cnc ps/polystyrene cutting machine] foam is type of plastic[plastic?:Plastic sample cutting machine] produced from styrene[styrene?:high precision styrene digital cutter]. It is a lightweight, moisture-resistant material with exceptional insulation properties. Since it is composed of more than 90 percent air, polystyrene foam is also remarkably buoyant. Polystyrene foam is often made life rafts and preservers since World War II.
Products made from polystyrene foam are typically blue. It is used to make insulation wrap for residential homes, commercial buildings, and plumbing systems. Polystyrene foam is also used in road construction as an insulation layer under pavement to deter the formation of cracks and potholes that occur from seasonal freezing and thawing of the soil beneath. Polystyrene foam is also made into materials used in craft projects.
In terms of environmental impact and hazards to human health, polystyrene foam manufacturing is regarded as the fifth major producer of hazardous waste.
