General purpose polystyrene (GPPS)

General purpose polystyrene (GPPS) is a type of polystyrene plastic that is used in a wide range of applications. It is a clear, lightweight plastic that is easy to work with and has good impact resistance.

GPPS is commonly used to make disposable plastic products such as cutlery, cups, and packaging materials. It is also used in the manufacturing of toys, electronic components, and automotive parts.

GPPS is a thermoplastic, which means it can be melted and reshaped multiple times. It has a high melting point and is resistant to heat and chemicals, making it a good choice for use in food packaging and other applications where it may come into contact with heat or chemicals.

Overall, GPPS is a versatile plastic that is widely used in a variety of industries due to its low cost and good performance properties.
