GPPS

General Purpose Polystyrene (GPPS) is a clear, rigid, and brittle thermoplastic that is a basic form of polystyrene. Known for its transparency and gloss, GPPS is used in applications where these properties are desired, combined with a relatively low cost and ease of processing. GPPS is commonly used in the production of items such as clear plastic cups, lids, and packaging trays, where product visibility is important. It is also used in the manufacture of lightweight rigid items such as CD cases, cosmetic containers, and household goods. GPPS exhibits good dimensional stability and is easy to process using standard plastic molding techniques, such as injection molding and extrusion. However, its brittleness limits its use in applications where high impact resistance is required. Additionally, GPPS has good electrical insulation properties, making it suitable for use in electrical and electronic components, such as switch plates, covers, and housing parts. The material can be easily colored or filled with additives to modify its properties for specific applications, further enhancing its versatility. Despite its widespread use, GPPS is often criticized for its environmental impact, as it is not biodegradable and can contribute to plastic waste in the environment. Nevertheless, recycling efforts and the development of biodegradable alternatives are being explored to address these concerns. GPPS remains a popular choice for applications that require clarity, rigidity, and cost-effectiveness.
