Chemical Resistance: Resists weak acids, weak alkalis, alcohols, aliphatic hydrocarbons, and other chemicals. (Note: Resistance is poor against strong acids, strong alkalis, and some organic solvents.)

Electrical Insulation: Serves as an excellent electrical insulator with good dielectric strength.

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.

Good Weather Resistance: Maintains stable physical properties across a wide temperature range from -40°C to 120°C (and even short-term higher), without becoming brittle. It exhibits good long-term anti-aging performance for outdoor applications.

Skylights & Canopies: Parking lot canopies, subway entrances, corridor awnings, swimming pool roofs. PC sheets are safer than glass (shatterproof) and lighter, reducing the load-bearing requirements for steel structures.

Curtain Walls & Partitions: Alternatives to glass curtain walls in shopping malls and office buildings (especially solid sheets or U-lock profiles), as well as privacy partitions and meeting room dividers in offices.

Greenhouses: Modern intelligent greenhouses, eco-restaurant roofs. Multi-wall PC sheets (twin-wall or polycarbonate sheets) offer better insulation than glass and can last over 10 years with UV protection layers to resist aging.

Planting Facilities: Small greenhouse boxes for balconies, plant tissue culture containers.

Q: 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.
