General Purpose Polystyrene (GPPS)
GPPS, or general purpose polystyrene, is a thermoplastic polymer that finds widespread use in various applications due to its unique characteristics. It is produced by polymerizing styrene monomers.
The distinguishing features of GPPS include its clarity, transparency, and high gloss, making it an ideal choice for applications like food packaging, disposable cups and plates, and CD cases. Additionally, its exceptional dimensional stability and low water absorption make it suitable for model-making and electrical insulation purposes.
One of the notable advantages of GPPS is its ease of processing, making it a cost-effective material for manufacturing. It can be effortlessly extruded, molded, and shaped into different forms and sizes.
Furthermore, GPPS exhibits excellent electrical insulation properties, making it valuable for applications that demand high electrical resistance, particularly in the production of electrical components.
However, it is important to note that GPPS has certain limitations. It is brittle and lacks impact resistance, which restricts its usage in applications requiring high strength or toughness. Additionally, GPPS is less heat-resistant compared to other thermoplastics like polycarbonate and polypropylene, limiting its suitability for high-temperature applications.
