HIPS (High Impact Polystyrene), also known as PS (Polystyrene), is an amorphous thermoplastic material, used in lower heat applications. It is categorized as a standard material, and offers ease of processing, high impact strength, and stiffness.
High impact strength
Can be printed using Digital, Screen, Flexo, and Litho inks
Fabricates well – can be guillotine cut, die-cut, punched and formed
Easy to Thermoform
Good dimensional stability
Fully recyclable with minimal loss of properties
FDA approved with 100% virgin resin
Dimensions: 48” x 96” up to 50” x 99”, custom up to 114″ wide
Thickness: 0.020” up to 0.250”
