polystyrenebased
Polystyrenebased refers to materials in which polystyrene is the primary polymer component or a major constituent. These materials span a range of thermoplastics and foams in which styrene-derived units form the main chain or matrix, often blended or copolymerized with other monomers to tailor properties. The base polymer is produced by free-radical polymerization of styrene, typically via emulsion, suspension, or bulk processes, and yields a family that includes homopolystyrene, styrene–acrylonitrile copolymers, and styrene-containing block or random copolymers.
Common polystyrenebased materials include crystalline or amorphous polystyrene (PS), which is rigid and transparent; styrene–acrylonitrile (SAN),
Key properties vary with formulation but typical PS-based resins exhibit a glass transition around 95°C, high
Applications span packaging, consumer electronics housings, insulation, automotive parts, and construction materials, where the balance of
