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.

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.

Bendability: Possesses good plasticity and flexibility, allowing for cold-curving at room temperature, making it suitable for arched structures like skylights.

Thermal Insulation and Sound Insulation: Multi-wall and hollow cell structures significantly reduce thermal conduction, offering better insulation than glass of comparable thickness. They also effectively reduce noise transmission.

2. Transportation & Automotive Engineering

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).

3. Agriculture & Horticulture

Leveraging thermal insulation and light diffusion properties.

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: Where are PC sheets commonly used?
A: Applications are vast and include:

Architectural Glazing: Skylights, roof lights, curtain walls, walkways.

Greenhouses & Agricultural Buildings: Provides excellent diffused light and insulation.

Noise Barriers: Along highways and railways.

Security & Safety: Security windows, bank teller screens, police riot shields, machine guards.

Signage & Displays: Lightbox panels, protective covers.

Retail & Residential: Canopies, patio covers, garage doors, partitions.
