Polystyrene (P.S) is a versatile polymer that comes in various grades, each tailored for specific applications. Here are a few common P.S grades and their applications:
General-Purpose Polystyrene (GPPS):
Application:
GPP.S is often used in applications where clarity and transparency are essential.
It’s commonly found in packaging materials, disposable cutlery, and CD jewel cases.
High-Impact Polystyrene (HIP.S):
Application: HIP.S is blended with rubber to improve impact resistance,
making it suitable for applications where toughness is crucial.
It’s used in refrigerator liners, toys, and some packaging.

Crystal Polystyrene (CP.S):
CP.S is known for its high clarity and gloss.
It’s used in applications where transparency and an attractive appearance are important,
such as cosmetic packaging and consumer goods.
Expandable Polystyrene (EP.S):
Application:
EP.S is a foam version of polystyrene known for its insulating properties.
It is widely used in packaging, thermal insulation (e.g., in construction),
and disposable foam products like food containers.
High Heat Resistant
Polystyrene (HIP.S-HR):
Application:
This grade is designed to withstand higher temperatures than standard HIP.S.
It is used in applications where heat resistance is crucial,
such as in food service items like hot beverage cups.
Remember that the choice of P.S grade depends on the specific requirements of the application,
including factors like clarity, impact resistance, heat resistance, and cost considerations.
