• PALSUN polycarbonate powerfully combines superior impact resistance and clarity, making it the material of choice for many demanding applications.

    PALSUN polycarbonate is virtually unbreakable, yet it is transparent as glass at less than half its weight. PALSUN polycarbonate can be cold bent and easily fabricated and formed, making it ideal for skylights.

    Unsurpassed by any clear glazing product on the market, MAKROLON polycarbonate sheet is hundreds oftimes stronger than plate glass and many times stronger than acrylic. This tough, long lasting material offers attractive protection in areas subject to high traffic, vandalism or burglary. It even withstands natural forces like severe wind, hail, and snow storms. In fact, MAKROLON polycarbonate sheet meets stringent state mandates for hurricane resistant glazing materials.

    Prolonged exposure to the sun can weather even the most durable of surfaces. In the past, acrylic was often chosen for plastic glazing applications because of its inherent resistance to yellowing over time. But compared to polycarbonate, the relative brittleness of acrylic made its impact strength insufficient for demanding, vandal resistant applications. To meet this need, Sheffield Plastics developed MAKROLON SL polycarbonate sheet. It offers the best of both worlds–the impact protection of MAKROLON polycarbonate sheet and the UV resistance of acrylic. Utilizing advanced formulations combined with state-of-the-art extrusion technology, Sheffield Plastics has created a tough, consistent quality product that will exhibit superior performance for years to come.

    Performance Warranty

    The performance of MAKROLON SL polycarbonate sheet has been well documented through years of laboratory and field testing. In side-by-side comparative testing under severe conditions, MAKROLON SL polycarbonate sheet consistently outperformed competitive materials utilizing older technology. Materials were also tested in forms and bends well beyond recommended guidelines, proving that the integrity of SL, as well as its UV resistance, will not change if the sheet is bent or cold-formed. So conclusive was this testing that Sheffield offers a limited warranty against excessive yellowing, loss of light transmission, and breakage.

  • Uniting incredible strength with aesthetic beauty, acrylic is the material of choice for thousands of products in many industries.

    Acrylic is a polymer created when giant carbon molecules combine chemically. Finished acrylic sheet exhibits glass-like qualities – clarity, brilliance, transparency, translucence – but at half the weight and up to 10 times the impact resistance. It can be tinted or colored, mirrored or made opaque. A number of coatings can be applied to a sheet or finished part for performance enhancing characteristics such as scratch resistance, anti-fogging, glare reduction and solar reflective.

    Because it’s a thermoplastic and softens under extremely high temperatures, acrylic can be formed to virtually any shape. Incredibly durable, acrylic is a suitable solution over a broad temperature range, and has superior weathering properties compared to other plastics.
