PC Lotte Chemical PC‑1100
Material Introduction: PC Lotte Chemical PC‑1100 is a medium‑viscosity general‑purpose polycarbonate material with well‑balanced overall performance. It is widely favored for high transparency, favorable mechanical strength, high rigidity, heat resistance, impact resistance and food‑contact compliance.
Main Applications
- Electronic & Electrical Components: Computer peripherals (keyboards, mice, computer cases, etc.), insulating connectors, coil bobbins, telephone housings, telephone exchangers, signal relays and other communication‑equipment parts.
- Mechanical Equipment: Gears, worm gears, worms, bearings, bolts, levers, crankshafts, as well as housings, covers and frames for mechanical devices.
- Medical Devices: Medical‑grade cups, tubes, bottles, dental instruments, drug containers and surgical instruments.
- Optical Applications: General‑purpose optical fields benefited from high transparency.
- Others: Extruded sheets and injection‑molded products.
