Polycarbonate (PC)
Polycarbonate is known for its high transparency and excellent impact resistance, and is commonly used in the manufacture of eyeglass lenses, bulletproof glass, and electronic device housings. It has good high-temperature resistance and maintains stability over a wide temperature range.
Polyoxymethylene (POM)
POM has high rigidity, wear resistance, and a low coefficient of friction, making it suitable for manufacturing precision mechanical parts such as gears, bearings, and zippers. It has good dimensional stability but poor acid and alkali resistance.
Polystyrene (PS)
Polystyrene is divided into ordinary PS and impact-resistant PS (HIPS). The former is brittle but has high transparency and is commonly used for disposable tableware and CD cases; the latter is more durable and suitable for appliance housings and toys.
Polymethyl methacrylate (PMMA)
Commonly known as "acrylic," it has excellent transparency and weather resistance, and is widely used in advertising light boxes, automotive taillights, and optical lenses. It has high surface hardness but is easily scratched.
