Can EPS be used for structural applications?

No, EPS lacks mechanical strength and is intended for insulation, cushioning, and lightweight non-structural uses.

Is EPS environmentally sustainable?

EPS is recyclable, but its low density makes collection and transportation more difficult compared to rigid plastics.

Because it combines excellent shock absorption, lightweight handling, and low production cost, making it ideal for protective packaging.

HIPS offers moderate chemical resistance but can be degraded by strong solvents or oils.

Yes, when produced with food-grade or medical-grade certification, HIPS can safely be used in packaging and healthcare products.

Because HIPS offers much higher impact resistance, making it more durable for consumer goods and industrial applications.

Yes, GPPS can be recycled, though collection and reprocessing depend on local recycling facilities.

Not recommended, as GPPS is sensitive to UV and weathering unless treated with stabilizers.

GPPS is transparent and rigid but brittle, while HIPS is opaque but offers higher toughness and impact resistance.
