        Masterbatch and Compounds for Polycarbonate and PMMA sheets

        Polycarbonate and PMMA Sheets

        Kafrit UV compounds are designed and tailored according to the customer‘s specifications and Kafrit‘s vast experience in this field. All Kafrit solutions are colored with a bluish tint to hide the UVA yellow shade, and contain optical-brightener to enable layer identification by the sheet producer. Kafrit is offering unique coloring abilities to meet customer demands.

        The compound flow properties are a key factor in uniform and stable layer distribution across the sheet‘s width. The Cap Layer flow is determined by the PC resin type, lubrication system level and, most importantly, the UV absorbers types and level.

        Kafrit solutions offer an optimized MVI based on years of experience. Our know-how allows us to offer a variety of MVIs according to the final application and production process.

        We use different types of UVA compounds and Masterbatches to insure optimal UV protection, process optimization and the best value each and every customer needs for their products.

        The UVA types differ in their chemistry, price and plate out level. Kafrit recently developed a new line of products that significantly improves performance in terms of plate out. Our new improved technology allows sheet producers to increase significantly the working interval between cleaning, therefore adding significant value to production efficiencies.

        Most PC sheets are protected by a thin co-extruded layer (Cap Layer). This layer is based on PC resin, enriched with a high level of UV absorbers. The recommended layer thickness is taking into consideration the layer erosion over the service life and the UV additive optical density, so no harmful UV light will penetrate the Cap Layer to the unprotected Polycarbonate.

        Anti-Glare

        The purpose of this product group is to eliminate the sheets‘ glossy surface appearance. As this is a surface phenomena, the AG products are always combined with UVA and applied to the sheets in the same manner as the UV cap layers.

         

        Flame Retardant

        Our lab developed skills and an extrapolation method of Flame Retardants to evaluate the FR performance using UL-94 and LOI tests. Different building standards require different testing methods using the final sheet structure produced by our customers.

        Heat Management

        Kafrit NIR PC Masterbatches are designed to insure that NIR is reflected and therefore allows architects and other users to insure that covered spaces are efficient and cost effective. Using unique proprietary we offer a wide range of optimized solutions to answer tomorrow‘s demand.

        Colors

        Kafrit specializes in PC and PMMA color matching and can match your color according to MB sample or product sample. It is also possible to perform a match according to RAL or Pantone, in such case it might be less accurate.

        Kafrit offers a wide selection of PC and PMMA colors; a catalog with standard color samples is available upon request.

        • Transparent colors
        • Opaque colors
        • Opal/diffusing colors

        Special Effects

        Pearlescent Effect: Kafrit developed a special technology for pearlescent MB and compound production.

        Metallic Effects: Based on aluminium pigments are often combined with different shades of pigments in order to reach the requested color (metallic green, for example).

        Kafrit offers a variety of pearlescent and metallic colors and can supply a special effect color catalog with sample chips upon request.
