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.
Benefits of High Impact Polystyrene (HIPS)
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
