PC plastics include carbonate groups in their chemical make-up. This engineering plastic type comprises thermoplastic polymers that combine toughness, rigidity, durability, and impact strength. They are easy to machine or mold to desired shapes. Additionally, polycarbonates offer good thermal, electrical, and weathering properties, unlike standard plastics. Some PC plastic grades are also optically transparent. Thus, this combined property makes it suitable for manufacturing motorcycle helmets, bumpers, and optical discs. Polycarbonate (PC) is a versatile and durable thermoplastic polymer known for its exceptional impact resistance and natural transparency.
