Sicostirolo® Polystyrene

Sicostirolo® industrial quality polystyrene, produced by Ravago, offers an economic solution for many applications where prime quality would be over-specified. The Sicostirolo® Polystyrene portfolio includes two major groups: industrial quality black and white high impact polystyrene (HIPS) grades and industrial quality general purpose polystyrene (GPPS), as well as flame retardant prime compounds (UL94: V-0).

Key Properties of Sicostirolo® PS Compounds:

• Economic solution for various applications

• Good impact and processability

• Suitable for applications requiring aesthetic properties

• Different properties balancing (flammability, stiffness, flowability, heat resistance)

Portfolio:

• Industrial Quality HIPS Grades: Available in black and white, offering good impact resistance and processability.

• Industrial Quality GPPS Grades: General purpose polystyrene suitable for various applications.

• Flame Retardant Prime Compounds: UL94: V-0 rated, suitable for applications requiring high fire safety standards.

Sicostirolo® 600 Series: HIPS resins V0 1.6 mm designed for injection moulding of a wide range of applications where aesthetic properties combined with good impact and processability are required. Depending on the composition, different properties can be balanced to meet application needs.

Processing:

For Sicostirolo® PS processing, the temperature settings of the injection moulding machine should be set at a uniform rate from 180°C to 260°C at the nozzle. Hot runners are not recommended for Sicostirolo® industrial quality grades.
