Polystyrene (PS) is a synthetic polymer made from the monomer styrene. It is a versatile plastic that can be rigid or foamed, and is commonly used in a variety of applications such as food packaging, insulation, and consumer products.
There are two main types of polystyrene:
General purpose polystyrene (GPPS): This is a rigid and transparent form of polystyrene that is commonly used in food packaging, disposable cups and plates, and CD cases.
High impact polystyrene (HIPS): This is a tougher and more impact-resistant form of polystyrene that is commonly used in refrigerator liners, toys, and automotive parts.
Polystyrene is an inexpensive and widely-used plastic, but it is not easily biodegradable and can have negative impacts on the environment if not disposed of properly.
