Polystyrene (PS) is a versatile thermoplastic polymer used widely in packaging, insulation, and consumer goods. It comes in three main forms:
General Purpose Polystyrene (GPPS) – clear, rigid, ideal for CD cases and food containers.
High Impact Polystyrene (HIPS) – tough, opaque, used in appliances and toys.
Expanded Polystyrene (EPS) – lightweight, excellent for insulation and protective packaging.
Ethylene Vinyl Acetate (EVA) is a flexible, transparent polymer known for its toughness, low-temperature resistance, and stress-crack durability. Commonly used in footwear, foam sheets, adhesives, packaging, and solar panels, EVA offers excellent impact resistance and processability.
PS offers ease of processing, dimensional stability, and cost-effectiveness, making it a popular choice across industries from construction to electronics.
