Message

Polystyrene is a highly transparent material. It gives excellent mechanical and heat resistance properties while providing with easy process ability and molding applications.

Characteristics:

No internal lubricant

Blue Tinted,

Excellent Clarity,

Good Flow, Low Volatility

(Below 1000 ppm)

Applications:

This grade is specifically suited for Extruded Polystyrene (XPS) production application as it comes without any lubricant to give end product a unified cell structure. Moreover, it can also be used for general injection moudling.
