Excellent Optical Properties: Features high light transmittance of up to 89%, comparable to glass. When coated with a UV-resistant layer, it effectively blocks ultraviolet light transmission and prevents the sheet from yellowing and hazing due to exposure to sunlight.

Lightweight: Has a low density, only about half that of glass, which reduces transportation, handling, and installation costs, and places less load on supporting structures.

Flame Retardancy: Has a high ignition point and is self-extinguishing upon removal of a flame. It does not produce toxic gases when burning. Its flame retardancy rating can reach Class B1, making it a flame-retardant engineering plastic.

High Heat and Cold Resistance: Retains good mechanical strength, rigidity, and dimensional stability in both high and low-temperature environments.

High Heat and Cold Resistance: Retains good mechanical strength, rigidity, and dimensional stability in both high and low-temperature environments.

Utilizing high impact resistance and lightweighting advantages.

Automotive Components: Headlamp covers (PC offers excellent transparency and high heat resistance), sunroofs, panoramic sunroofs, instrument panel bezels, power windows.

Rail Transit & Aviation: High-speed rail windows, aircraft windows, soundproof barriers in subway stations (solid PC sheets).

Utilizing flame retardancy (some grades reaching V0 rating) and electrical insulation.

Electronics: Mobile phone cases, laptop shells, water dispenser bottles (PC is one of the few plastics approved for food contact), electricity meter boxes.

Industrial Equipment: Machine safety guards, soundproof barriers, riot shields, helmet visors (police riot shields, motorcycle helmet visors).

What is the difference between Polycarbonate (PC) and Acrylic (PMMA) sheets?
A: This is a common question. Key differences are:

Impact Strength: PC is vastly more impact-resistant and shatterproof than acrylic.

Flexibility: PC is highly flexible (can be cold-curved), while acrylic is rigid and brittle.

Heat Resistance: PC has a higher heat deflection temperature (~120°C / 250°F) than acrylic (~80°C / 176°F).

Surface Hardness: Acrylic has a harder surface and is much more scratch-resistant. Standard PC sheets are prone to scratching without a protective coating.

Cost: PC is typically more expensive than acrylic.

Q: What are the main types of Polycarbonate Sheets?
A:Solid Sheets: Single, solid layer. Offers the highest clarity and impact resistance. Used for security glazing, machine guards, and protective barriers.

Multi-Wall / Hollow Sheets: Feature 2+ walls with flutes (ribs) between them. Provide excellent thermal insulation and are lightweight. Ideal for roofing, skylights, greenhouses, and canopies.

Corrugated Sheets: Wave-like profile. Typically solid. Used for industrial roofing and siding where high strength and weather resistance are needed.
