GPPS General Purpose Polystyrene

General purpose polystyrene (GPPS) is a type of thermoplastic polymer that is widely used in a variety of applications due to its unique properties. GPPS is made from styrene monomers, and is formed by a process called polymerization.
GPPS is characterized by its clarity, transparency, and high gloss, which make it ideal for use in applications such as food packaging, disposable cups and plates, and CD cases. Its excellent dimensional stability and low water absorption also make it useful for applications such as model-making and electrical insulation.
One of the advantages of GPPS is its ease of processing, which makes it a cost-effective material for manufacturing. It can be easily extruded, molded, and formed into a variety of shapes and sizes.
Another advantage of GPPS is its good electrical insulation properties, which makes it useful for applications that require a high degree of electrical resistance, such as in the production of electrical components.
However, GPPS is brittle and has low impact resistance, which limits its use in applications that require high strength or toughness. It is also less heat-resistant than other thermoplastics such as polycarbonate and polypropylene, which limits its use in high-temperature applications
