GPPS is a clear polymer that exhibits high stiffness, good dimensional stability, low specific gravity and excellent electrical properties. It offers several advantages over other polymers because of its clarity and ease of processing, both of which are due to its amorphous nature.
GPPS has a relatively low cost and is forgiving when processed at high production rates. Extrusion and injection molding continue to be the predominant processing technologies for PS. Key end use markets for PS include food packaging, refrigeration, audio/video, consumer electronics and office equipment, medical devices, and toys.
