Research that takes us to the top
Research and development are Kafrit’s key areas
of expertise. A staff of 386 employees works
on innovative products, based on fundamental
knowledge of more than 40 years.
They develop and optimize additive concentrates, flame retardants, color concentrates and
compounds for various applications. Kafrit has
close cooperation with well-known institutes
like Shenkar University (Israel) and University of
Salerno (Italy). Furthermore, we have a close
relationship to well-known suppliers as well as
machine suppliers who recommend our products
to be used on their machines.
Our vision:
We aim to be the
preferred technological
partner for the plastics
indus­try, providing our global
customers with long-term
innovative and quality
solutions suited to their
needs.
Polycarbonate
2. Anti-Glare
All 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.
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 demand.
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 type, lubricant 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 purpose of this product group is to eliminate the sheets‘ glossy surface appearance. As this is a
surface “problem”, the AG products are always combined with UVA and applied to the sheets in the
same manner as the UV cap layers.
The effect obtained can also be referred to as a “matt-effect”. The AG products are based on crosslinked polymeric spheres (similar to the light diffuser additives) that create a kind of micro-structure on
the surface and, as such, interfere with the glossy appearance. The AG products contain different types
of polymeric spheres, with different diameters. Both parameters are very important factors in the AG‘s
performance, appearance and processability. It is recommended to apply the AG compounds at a layer
thickness of 40-50µ to get the best effect.

6. Flame Retardants
The Single Burning Item standard (SBI) EN 13823 is the main building standard for PC sheets in
Europe. The same goes for the ASTM E84 in North America. In addition to the various required standards in different countries, the PC sheet geometry, type of polycarbonate resin mixed with the FR MB,
thickness and weight have an important impact on the FR performances.
The various factors described above are used by our experts and customers alike to offer a suitable
solution so as to fulfill the requirements of the standards.
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.
