At Excelite, we make our optical polycarbonate sheet from our high-quality custom resin. It offers many technical advantages, including exceptional impact resistance, light transmission rates of up to 89%, UV protection, and virtually unbreakable properties.

These solid polycarbonate sheets provide design flexibility. We can cold-form, cold-bend, cnc-machine them. This makes them an ideal choice for various indoor and outdoor projects, such as safety barriers, solid polycarbonate roofing sheets, and greenhouse applications.

Polycarbonate is a versatile thermoplastic polymer known for its impressive strength, smooth surface, and optical clarity. Polycarbonate solid sheets are virtually unbreakable, allowing them to withstand high impacts up to 250 times greater than traditional glass.

These sheets include clear solid polycarbonate sheet and translucent polycarbonate sheet. They are lightweight, easy to handle and install, and can be cold-formed into curved shapes with a minimum bending radius of 150 times their thickness. Their inherent UV protective layers ensure long-lasting durability and resistance to discoloration.

Transparent polycarbonate sheets showcase various technical properties, making them suitable for different applications and environments. These high-performance sheets come in thicknesses ranging from 0.125″ (1/8 inch) to 0.5″ (1/2 inch), depending on the project’s requirements. They can endure temperatures ranging from -40°F to 240°F, making them ideal for versatile outdoor applications, including polycarbonate roofing sheets.

Our clear polycarbonate panels can be tailored to fit any project’s specific needs. We offer various thicknesses, dimensions, and color tints to suit your application. Our precise cutting and fabrication techniques provide ideal sizing while maintaining the material’s high-quality appearance and properties.

FAQ

Polycarbonate sheets may yellow over time, which is influenced by the material quality and the presence of protective coatings. Excelite’s clear polycarbonate sheets have UV coatings on both sides and come with a 10-year warranty.

Yes, clear polycarbonate sheets are more prone to scratching compared to some other materials, such as glass or acrylic. But we offer polycarbonate sheets with scratch-resistant coatings that can help improve durability and reduce the likelihood of scratches.

Polycarbonate sheet material is known for its high impact resistance and durability.  To drill holes in polycarbonate, use an ordinary iron or HSS drill bit. Position the drill perpendicular to the sheet and run it at medium speed, applying light pressure. A slightly used but sharp drill bit is best to avoid “biting” into the  material. 

And don’t drill too close to the edge.

The lifespan of Excelite® polycarbonate sheet typically ranges from 10 to 15 years, depending on factors such as material quality, UV protection, environmental exposure, and maintenance. PC Sheets with UV-resistant coatings generally last longer.

No, polycarbonate and Perspex (acrylic sheet) are not the same. While both are transparent plastic materials, polycarbonate is more impact-resistant, tougher, and flexible, making it nearly unbreakable. Perspex, also known as acrylic, is more rigid and has a higher clarity but is more prone to cracking and shattering under impact. Polycarbonate is better suited for applications requiring durability and impact resistance, whereas Acrylic is often chosen for its optical clarity and scratch resistance.

For bonding polycarbonate, several types of adhesives are suitable, each offering specific benefits:

  1. Epoxy Resin:

    • Recommended for strong and durable bonds, making it ideal for polycarbonate.

  2. Two-Component Polyurethane Adhesive:

    • Offers quick curing with good strength and toughness.

  3. Acrylic Adhesives and Silicone Adhesives:

    • Versatile options that provide flexibility and environmental resistance.

  4. UV-Curing Adhesives:

    • Suitable for applications requiring fast curing, though less effective on polycarbonate.

Overall, epoxy resin is the preferred choice for achieving a strong, reliable bond with polycarbonate.
