Poly Styrene

Description

Polystyrene is a synthetic aromatic hydrocarbon polymer made from the monomer styrene.

• Chemical Formula: (C₈H₈)ₙ
• CAS Number: 9003-53-6

Properties

• Appearance:Typically, a clear, colorless solid; can also be found in expanded (foamed) forms (e.g., Styrofoam).
• Density: Low-density versions (expanded) are lightweight, while solid polystyrene is denser.
• Thermal Stability: Has good thermal insulation properties but can melt or deform at high temperatures.
• Chemical Resistance: Not very resistant to solvents; can be affected by many chemicals.

Applications

• Packaging:

Food Containers: Used in disposable cups, plates, and takeout containers.
Protective Packaging: Often used for cushioning fragile items during shipping.

• Construction:

Insulation: Expanded polystyrene (EPS) is commonly used as insulation in buildings.
Decorative Molding: Used for architectural elements due to its lightweight nature.

• Consumer Goods:

Toys: Many plastic toys are made from polystyrene.
Household Items: Includes storage containers, kitchenware, and more.

• Electronics:

Insulation for Electronic Components: Used in casings and insulating materials.

• Medical:

Petri Dishes and Laboratory Equipment: Commonly used in laboratories for its clarity and ease of sterilization.
