Technology GPPS/HIPS

At the heart of the GPPS/HIPS technology is the unique reactor design with its plug flow characteristics, excellent temperature control and chemically initiated polymerisation system. This allows exceptional control of product properties through regulating molecular weight and molecular weight distribution. Other significant advantages of the technology include:

	a highly efficient devolatilisation process enabling products suitable for food contact applications
	a proprietary and patented means to selectively improve the styrene recovery system
	extremely high reactor productivities which ensure rapid grade transitions without sacrificing product quality
	significant unit flexibility through high turndown capability without affecting product properties
	excellent operability and high on-stream times, confirmed by operating plants with proven long run times
	safe and environmentally clean operation

With the collective experience of commercially proven operation and ongoing process developments, single reactor plant capability has now reached 130 ktpa.
