There is a growing global trend to integrate transparent plastic sheets in place of glass in building applications such as malls, swimming pools, train stations and DYI. The most commonly used option is polycarbonate (PC) sheets, which are produced in solid, multiwall or corrugated form.<\/p>

Each form of the PC sheets has its own production challenges. Because polycarbonate is a transparent polymer, its optical properties are of utmost importance, along with optical manipulations where transparent colors, light diffuser and near-IR heat shielders are used. At Tosaf, we offer a comprehensive range of solutions for PC sheet producers.<\/p>

UV Protection <\/strong><\/h3>

PC is very sensitive to UV radiation, exposure to the solar radiation, without proper protection tend rapidly to develop high level of yellowness and later on crakes & fractures. UV protection is achieved through the co-extrusion of UV compounds, but the high level of UV absorber additive in the UV cap layer tends to migrate during the production process, affecting extrusion efficiency. As sheet producers work towards improving the extrusion and co-extrusion process, we have taken on the challenge of developing a range of optimized UV protection additives for use in the production of solid and multiwall sheets.<\/p>

Light Diffusion Protection <\/strong><\/h3>

One of the problems of a clear cover is that it lets in direct visible light, causing an uncomfortable glare. By introducing a light diffusion (LD) system into the PC sheet bulk, the glare is eliminated. We offer several such solutions in both MB and compound form.<\/p>

Near IR (NIR) Absorber <\/strong><\/h3>

Clear PC lets in NIR energy which, especially in hot climates, can cause a \u2018greenhouse\u2019 effect in buildings where these sheets are used. We have developed a range of masterbatches based on special pigments that selectively block the NIR energy, significantly reducing the amount of energy transmitted into the building with minimal effect on visible light.<\/p><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t

      UV<\/h3>

      UV Cap Layer<\/p>

      In PC sheets, protection from solar radiation is achieved by a thin co-extrudate cap layer. We offer several grades of UV cap layer suitable for either solid or multi-wall sheets, containing optical brightener to make the layer visible in the lab and
      gently tinted with a bluish dye to counter the yellow color of the UV absorber.<\/p>

        FR<\/h3>

        FR for PC Sheets<\/p>

        In PC sheets, the main challenge in adding additives is to maintain the original transparency properties of the polycarbonate. We have developed several flame-retardant solutions that have minimal effect on the sheets\u2019 transparency, causing no reduction in light transmission and an increase of only 1-2% in the original value of the haze. For opaque sheets, we offer a very effective halogen-free solution.<\/p>

          NIR<\/h3>

          Near IR Blocker<\/p>

          One of the main drawbacks of using a transparent cover or roofing in construction is that it lets in near-infrared (NIR) energy, creating a \u2018greenhouse\u2019 effect that causes the covered area to become very hot. Our NIR masterbatch absorbs most of the NIR energy, with minimum effect on transparency to visible light.<\/p>

              Anti-Block for PC Corrugated Sheets<\/p>

              Due to static electrical forces and the absence of masking film, it can be a challenge to separate single PC corrugated sheets from the pallet. Tosaf\u2019s simple, cost-effective anti-block additive resolves the issue, without affecting the production process or the optical properties of the sheets themselves.<\/p>

                GF<\/h3>

                Glass Fiber MB<\/p>

                Unlike other polymers that are reinforced with glass fiber, polycarbonate sheets have excellent mechanical properties. Where glass fiber is used, it is for aesthetic purposes, giving the sheet a \u2018broken\u2019 or \u2018hammer\u2019 effect. Our glass fiber masterbatch contains 20% glass fibers, requiring only 2%-3% addition rate to achieve the desired effect.<\/p>
