PS 330 is a high-impact polystyrene manufactured by continuous mass polymerization of styrene monomer, incorporating elastomers during polymerization to enhance impact resistance. Generally opaque in appearance, PS 330 offers high impact strength, elevated heat deflection temperature, and excellent physical properties, making it suitable for demanding applications where toughness and durability are required.

Applications:

• Extrusion and thermoforming applications
• It can be used for food packaging and dairy products

Polystyrene 125 is a general-purpose polystyrene manufactured via continuous mass polymerization of styrene monomer. It is a crystal-clear, hard, and brittle polymer with medium flow characteristics and high optical clarity. Featuring medium Vicat softening and heat deflection temperatures, Polystyrene 125 is suitable for a wide range of applications requiring rigidity and transparency.

Applications:

• Packaging items – namely jewelry and gift boxes
• Medical supplies – such as Petri dishes, test tube holders and specimen jars.

It can also be used in capping the high-impact polystyrene coextruded sheet for higher surface gloss and can be blended with impact modifier resin for clear packaging articles.
