Today, you have most likely used products containing polycarbonate without even realizing it. This is because polycarbonate is nearly everywhere: it is widely used in eyeglasses, medical devices, automotive parts, lighting fixtures, DVDs, Blu-ray discs, and many other products.
In fact, polycarbonate sheet is a transparent thermoplastic. It boasts extremely high strength and is nearly non-absorbent, enabling excellent resistance to impact and water erosion. Additionally, it is flame-retardant and chemically resistant. Two of the most remarkable properties of this sheet are its effective heat and cold insulation, with a temperature resistance range from -40°C to 130°C. Furthermore, it has a light transmittance of up to 88% and outstanding UV protection.
As a result, PC Lite polycarbonate sheets are widely used in the construction of railway station roofs, greenhouses, pedestrian bridges, walkways, swimming pools, shopping malls, airports, and various other facilities. They are also commonly applied in exterior wall cladding and glazing systems.
Why Choose Polycarbonate Sheets?
Polycarbonate sheets have a high glass transition temperature (145°C–150°C). Combined with special UV co-extrusion technology that reflects infrared radiation and a multi-wall structure, they effectively reduce thermal conductivity.
While similar materials deform at 70°C, polycarbonate sheets maintain structural integrity at temperatures as high as 120°C.
Made from 100% virgin raw material and coated with an 80-micron UV-protective layer, these sheets can lower indoor temperatures by 10–15°C and prevent material degradation caused by high heat. They are suitable for nearly all daily applications.
Are Polycarbonate Sheets Better Than Glass?
At the same thickness, polycarbonate sheets outperform glass in impact resistance, weatherability, and flame retardancy. They are coated with a 50-micron UV-protective layer that effectively shields the sheet from UV damage. Polycarbonate sheets also offer excellent toughness and can be bent, making them adaptable to a wide range of scenarios.
How to Maintain Polycarbonate Sheets?
Regular Cleaning
Regular cleaning is essential to prevent the buildup of dirt, debris, and stains that can affect appearance and performance. Follow these steps for effective cleaning:
a. Remove loose debris: Use a soft brush or broom to clear leaves, branches, and other loose materials from the surface.
b. Rinse with water: Thoroughly rinse the sheet with a garden hose to remove remaining dust and dirt.
c. Gently clean: Prepare a solution of warm water and neutral dish soap, then gently scrub with a soft sponge or cloth, focusing on stubborn stains and grease.
d. Rinse completely: Rinse thoroughly with clean water to remove all soap residue and avoid water spots or film formation.
e. Dry: Allow the sheet to air dry or pat gently with a lint-free cloth.
Do not use abrasive materials, as they may scratch the surface.
Avoid Harsh Chemicals and Abrasives
When cleaning polycarbonate roofing sheets, never use harsh corrosive chemicals or abrasive materials, as they may damage or scratch the surface.
Use only neutral dish soap or specialized cleaners recommended by the manufacturer.
Ammonia-based cleaners, solvents, and abrasive brushes are strictly prohibited, as they may cause discoloration or structural damage.
Inspection and Maintenance
Regularly inspect polycarbonate roofing sheets for damage or signs of aging, such as cracks, chips, loose fasteners, or sheet displacement.
Address issues promptly to prevent further damage. Follow the manufacturer’s guidelines or consult professionals for repairs.
What Colors Are Available for Polycarbonate Sheets?
Polycarbonate sheets on the market come in a wide range of colors, including clear, lake blue, sapphire blue, grass green, bronze, red, yellow, and more. These colors are vibrant, and custom color options are available to meet diverse customer requirements.
What Is the Raw Material of Polycarbonate Sheets?
The virgin raw material for polycarbonate sheets is petroleum.
After processing in polyester chip factories, petroleum is converted into polyester chip pellets. Plastic plants further process these pellets into feedstock for finished products — such as PC hollow sheets, PC solid sheets, and PC corrugated sheets. These are then fabricated and assembled into carports, awnings, greenhouses, and other structures.
Polyester pellets can be used across daily life and industry:
Agriculture: Applied in agricultural films, water pipelines, farm machinery, fertilizer bags, and cement bags.
Daily use: Recycled polyester pellets are made into plastic bags, buckets, basins, toys, furniture, stationery, and other plastic products.
Apparel industry: Used to produce clothing, ties, buttons, and zippers.
Construction materials: Manufactured into building components, tools, plastic doors and windows, and decorative materials.
