HIPS is one of the most widely used plastics and popular within the point of sale, display and signage market due to its visual appearance (colour options, gloss level, texture), the ease with which it can be processed along with its antistatic and electrical conductivity.

A versatile, cost-effective, impact-resistant material, which is easy to vacuum form, extrude, bend and mould into shape. It boasts extreme malleability and can be re-moulded over and over, making it environmentally friendly, as it can be recycled.

The rubber content gives it extra durability and impact strength and often used by vacuum formers and fabricators for commercial and industrial applications including handling trays, children’s toys, automotive and appliance components.

High Impact Polystyrene is strong, safe to use, cost-effective, versatile, and recyclable.
