PC SHEETS
PC Sheets, also called Polycarbonate sheets, are transparent or opaque thermoplastic sheets made from polycarbonate resin, a high-performance polymer synthesized from bisphenol A (BPA) and phosgene. Renowned for their exceptional impact resistance (250 times stronger than glass), optical clarity, and thermal stability, PC sheets are used in industries requiring lightweight, durable, and safety-critical materials. They are manufactured via extrusion or injection molding and are available in various forms, including solid, multiwall, corrugated, and textured sheets.
Key Features:
High Impact Strength – 250 times stronger than glass and 30 times stronger than acrylic.
Excellent Transparency – Up to 90% light transmission, similar to glass.
UV Resistance – Protects against yellowing and degradation from sunlight.
Weather & Chemical Resistance – Suitable for extreme temperatures and exposure to chemicals.
Flame Retardant – High ignition resistance, rated UL94 V-0.
Thermal Insulation – Good heat insulation properties, reducing energy costs.
Lightweight – Half the weight of glass, making it easier to handle and install.
Ease of Fabrication – Can be cut, bent, drilled, and thermoformed.
Noise Reduction – Used in sound barriers for highways and industrial settings.
Types:
PC sheets come in various forms, each designed for different applications:
Type | Properties | Applications |
Solid PC Sheets | Smooth, transparent/opaque, high impact resistance. | Safety glazing, machine guards, riot shields. |
Multiwall PC Sheets | Hollow, multi-chamber design; excellent insulation and light diffusion. | Greenhouses, skylights, sound barriers. |
Corrugated PC Sheets | Wavy profile for rigidity; UV-resistant and lightweight. | Roofing, agricultural covers, signage. |
Textured PC Sheets | Frosted or patterned surfaces for diffused light and privacy. | Partitions, decorative panels, lighting covers. |
UV-Coated PC Sheets | Dual-side UV protection for outdoor use (10–15-year warranty against yellowing). | Canopies, automotive glazing, solar panels. |
Anti-Static PC Sheets | Surface resistivity 10⁶–10⁹ Ω/sq; prevents dust attraction. | Electronics manufacturing, cleanroom equipment. |
Fire-Rated PC Sheets | UL 94 V-0 compliant; low smoke emission. | Public transport, aerospace, building interiors. |
Colored PC Sheets | Pre-dyed (e.g., bronze, opal, translucent) for aesthetics or light filtration. | Architectural cladding, artistic installations. |

Storage & Handling:
Temperature: Store at 10–30°C; avoid prolonged exposure to >70°C.
UV Protection: Keep UV-coated sheets in original packaging until use; avoid direct sunlight.
Humidity: Store in dry conditions (<60% RH) to prevent moisture absorption.
Handling: Use edge protectors to avoid scratches; stack flat on padded surfaces.
Cutting: Remove protective film only after installation to prevent surface damage.
FAQ
Q1: How do PC sheets compare to glass?
A: PC sheets are 250 times stronger than glass, significantly lighter, and shatter-resistant, making them a safer alternative.
Q2: Can PC sheets be cut and drilled?
A: Yes, they can be easily cut with saws and drilled without cracking.
Q3: Are PC sheets heat resistant?
A: Yes, they can withstand temperatures from -40°C to 120°C without deformation.
Q4: Are PC sheets recyclable?
A: Yes, polycarbonate is 100% recyclable and widely reused in manufacturing.
Q5: Can PC sheets be bent or shaped?
A: Yes, they can be cold-bent or thermoformed for custom applications.
Q6: Does PC sheet yellow over time?
A: Uncoated PC yellows under UV exposure. UV-coated sheets (e.g., Makrolon® UV) resist yellowing for 10+ years.
Q7: What solvents damage PC?
A: Avoid acetone, ketones, and aromatic hydrocarbons (e.g., benzene). Use isopropyl alcohol for cleaning.
Q8: How do PC sheets compare to acrylic in outdoor use?
A: PC outperforms acrylic in impact resistance and UV stability but is more expensive.
Q9: What are the advantages of PC Sheets over competing material, such as Glass, Acrylic, PET, PE, and PVC?
A:
vs. Glass: Shatterproof, lightweight, and easier to install.
vs. Acrylic (PMMA): Higher impact resistance and thermal stability.
vs. PET: Superior UV resistance and durability.
vs. PVC: Better optical clarity and environmental resistance.
vs. Polyethylene (PE): Higher rigidity and dimensional stability.
