HIPS stands for High Impact Polystyrene, a modified amorphous thermoplastic derived from general-purpose polystyrene (GPPS). Pure GPPS is extremely brittle and cracks easily upon slight collision.

Plastic materials are indispensable in daily life, with Polypropylene (PP) and Polycarbonate (PC) being two of the most widely used polymers for food containers, water bottles, home appliances and industrial parts.

If you have ever compared plastic water cups side by side, you may have noticed a clear difference: PC cups are bright and crystal transparent, while PP cups always show a milky, foggy or semi-transparent matte look.
