PC Solid Sheet

Impact Resistance
Solid polycarbonate sheets are virtually unbreakable and can withstand significant impacts without shattering. This property makes them ideal for applications where safety is a concern.

Transparency
These sheets offer excellent optical clarity, allowing light to pass through with minimal distortion. They transmit light better than glass and can be chosen in different degrees of transparency.

UV Protection
Many solid polycarbonate sheets are treated with UV-resistant coatings to prevent yellowing and degradation from prolonged exposure to sunlight.

Thermal Insulation
Polycarbonate has good insulation properties, helping to maintain stable temperatures in enclosed spaces.

Lightweight
Solid polycarbonate sheets are much lighter than glass of comparable thickness, making them easier to handle and install.

Easy to Work With
They can be easily cut, drilled, and shaped using standard tools, making them suitable for various custom applications.

Toughness
PC Solid Sheet maintains a toughness value between -20°C to 140°C. They are virtually unbreakable.

High Impact Strength
PC has a high strength that makes it resistant to impact and fracture. It provides safety and comfort in applications that demand high reliability and performance. The polymer has a density of 1.2-1.22

Transmittance
PC Solid Sheet is an extremely clear plastic that can transmit over 90% of light as good as glass. Polycarbonate sheets are available in a wide range of shades. These sheets can be customizable depending on an end-user application.

Lightweight
This feature allows virtually unlimited possibilities for OEMs to design as compared with glass. The property increases efficiency and makes the installation process easier. It also reduces overall transportation costs.

Protection from UV Radiations
PC Solid Sheet can be designed to block ultraviolet radiation. They provide 100% protection from harmful UV rays.

Optical Nature
For having an amorphous structure, PC Solid Sheet offers excellent optical properties. The refractive index of clear polycarbonate is 1.584.

Chemical Resistance
Good chemical resistance against diluted acids, aliphatic hydrocarbons, and alcohols. It shows moderate resistance against oils and greases. PC is readily attacked by diluted alkalis, aromatic, and halogenated hydrocarbons. Manufacturers recommend cleaning PC using agents which do not affect their chemical nature. It is sensitive to abrasive alkaline cleaners.

Heat Resistance
PC Solid Sheets have high heat resistance. They are thermally stable up to 135°C. Further heat resistance can be improved by adding flame retardants without impacting material properties.

Raw Material Preparation
The first step is preparing the polycarbonate resin by blending BPA with stabilisers and UV absorbers. This mixture is melted to form a homogenous liquid.

Extrusion
The molten polycarbonate resin is then fed into an extruder, which applies pressure and heat to further melt the material. The extruder consists of a screw that pushes the molten resin through a die, shaping it into a continuous sheet.

Cooling and Solidification
As the extruded polycarbonate sheet exits the die, it passes through a series of cooling rollers or a water bath to rapidly cool and solidify the material. This controlled cooling process helps prevent warping and ensures uniform thickness across the sheet.

Trimming and Finishing
After solidification, the polycarbonate sheet is trimmed to the desired dimensions. It may undergo additional processes like surface treatments (e.g., UV protection coating) or texturing for specific applications.

Quality Control
Throughout the manufacturing process, quality control measures are implemented to ensure the final product meets the required standards. This includes checking for defects, verifying thickness and clarity, conducting various performance tests, etc.

Safety First
Always start by ensuring your safety. Wear safety goggles, gloves, and sturdy footwear throughout the installation process. If working at a height, ensure that you use secure ladders or scaffolding.

Planning and Measuring
Begin by planning your layout and measuring the area to be covered. This helps determine the number of polycarbonate sheets, purlins, or rafters needed. Remember to allow for an overhang on the gutter of at least 50mm.

Cutting the Sheets
If necessary, cut the polycarbonate sheets to size using a fine-toothed circular saw for straight cuts. Remember to peel back the protective film on the cut areas to prevent it from melting and sticking to the sheets. Always cut the sheets on a flat surface to avoid damaging them.

Pre-drilling Holes
Polycarbonate sheets expand and contract with temperature changes. To accommodate this, pre-drill oversized holes for the screws. The holes should be 10% larger than the diameter of the screw shank.

Sealing the Edges
Before installing the sheets, seal the top end with solid polycarbonate tape and the bottom end with anti-dust tape. This prevents dust, dirt, and insects from entering and stops water from being drawn up through capillary action.

Positioning the Sheets
Start from the opposite end to the prevailing wind. Position the first sheet onto the purlins, ensuring the side with the UV protective layer faces upwards–some brands of roofing sheets are only UV-coated on one side. The sheet should overhang the roof at the lower end and the gutter end.

Fixing the Sheets
Secure the sheet using polycarbonate compatible screws and washers. Do not overtighten the screws as this can lead to water leakage and prevent the sheet from expanding and contracting. The washers should be compressed but still visible. Continue attaching the sheets, ensuring they overlap by at least one corrugation or as recommended by the manufacturer.

Sealing the Joints
Apply a bead of silicone sealant to the side lap where each sheet overlaps. This helps prevent water leakage.

Installing Flashing
Install the ridge flashing or capping over the joints where two sheets meet on a roof peak. Ensure it's sealed on both sides with silicone sealant to prevent water leakage. The flashing not only helps in waterproofing but also adds a neat finish to your roofing.

Finishing Touches
Inspect your work thoroughly. Make sure all screws are tightened appropriately (without being overtightened), all joints are sealed, and that the sheets are secure.

Safety first
Safety is paramount, especially when working at heights. While it's essential to reach the roof area for various tasks, exercising caution is crucial. One key point to remember is to avoid walking directly on polycarbonate sheets. Instead, opt for safer alternatives like using extension poles whenever possible. If you must step onto the roof, utilize crawl boards to distribute weight evenly and minimize risks. Always prioritize adhering to the manufacturers' guidelines on accessing the roof area to ensure a secure and accident-free work environment. Your safety is our top priority!

Cleaning basis
Maintaining the pristine appearance of your polycarbonate sheets is a breeze with the right cleaning approach. A mild detergent mixed with warm water is highly effective for most polycarbonates. To avoid any scratches, use a soft cotton cloth or a gentle bristled brush during cleaning. Prior to cleaning, give the sheets a thorough hose down to remove larger debris that may cause scratches when subjected to mechanical rubbing.

Beware cleaning solutions
Certain commercial cleaning solutions may not be compatible with polycarbonate and can potentially cause damage, leading to premature breakdown of the material. To ensure the longevity and optimal performance of your polycarbonate sheets, it is crucial to use cleaning solutions that are specifically designed and approved for use with polycarbonate. Always check the manufacturer's recommendations or consult with experts to identify safe and effective cleaning products that will preserve the integrity of your polycarbonate sheets and keep them in pristine condition for years to come.

Troublesome spots
After washing your roof with a mild detergent, check for any remaining areas that need attention. If necessary, consult the manufacturer's chemical resistance guidelines. Be cautious with chemicals, as some can damage the sheeting. Always remember to thoroughly rinse the sheets after using any cleaning chemicals.
