Thanks to their surface structure with a slight glare (without being reflective), our polycarbonate light diffuser films are characterised by good and constant printability. Furthermore, our diffuser films can be cut, punched, lasered (partly possible), embossed and glued using professional accessories. Polycarbonate light diffuser films are suitable for deep drawing and back injection and the insert moulding process (FIM) as well as high pressure forming (HPF). The films we offer can be cold and hot formed. Our polycarbonate light diffusion films are also suitable for special applications such as deep drawing or high-pressure forming.

Translucent diffusor materials are designed for light diffusion in high quality lighting applications. These films in milky white color contain a scattering additive specially developed for this application for uniform light diffusion. When used in backlit components using LED light, our light diffusion films provide uniform and homogeneous illumination over a wide area.

Polymethyl methacrylate was discovered in the early 1930s by British chemists Rowland Hill and John Crawford at Imperial Chemical Industries (ICI) in England. ICI registered the product under the trademark Perspex. About the same time, chemist and industrialist Otto Röhm of Rohm and Haas AG in Germany attempted to produce safety glass by polymerizing methyl methacrylate between two layers of glass. The polymer separated from the glass as a clear plastic sheet, which Röhm gave the trademarked name Plexiglas. Both Perspex and Plexiglas were commercialized in the late 1930s. In the United States, E.I. du Pont de Nemours & Company (now DuPont Company) subsequently introduced its own product under the trademark Lucite. The first major application of the new plastic took place during World War II, when PMMA was made into aircraft windows and bubble canopies for gun turrets. Civilian applications followed after the war.

The presence of the pendant methyl (CH3) groups prevents the polymer chains from packing closely in a crystalline fashion and from rotating freely around the carbon-carbon bonds. As a result, PMMA is a tough and rigid plastic. In addition, it has almost perfect transmission of visible light, and, because it retains these properties over years of exposure to ultraviolet radiation and weather, it is an ideal substitute for glass. A most successful application is in internally lighted signs for advertising and directions. PMMA is also employed in domed skylights, swimming pool enclosures, aircraft canopies, instrument panels, and luminous ceilings. For these applications the plastic is drawn into sheets that are machined or thermoformed, but it is also injection-molded into automobile lenses and lighting-fixture covers. Because PMMA displays the unusual property of keeping a beam of light reflected within its surfaces, it is frequently made into optical fibres for telecommunication or endoscopy.

PMMA, an ester of methacrylic acid (CH2=C[CH3]CO2H), belongs to the important acrylic family of resins. In modern production it is obtained principally from propylene, a compound refined from the lighter fractions of crude oil. Propylene and benzene are reacted together to form cumene, or isopropylbenzene; the cumene is oxidized to cumene hydroperoxide, which is treated with acid to form acetone; the acetone is in turn converted in a three-step process to methyl methacrylate (CH2=C[CH3]CO2CH3), a flammable liquid. Methyl methacrylate, in bulk liquid form or suspended as fine droplets in water, is polymerized (its molecules linked together in large numbers) under the influence of free-radical initiators to form solid PMMA. The structure of the polymer repeating unit is: .

Makrofol® LM309 2-4 160004 is an extruded polycarbonate (PC) film filled with a light-scattering agent for an even diffusion of light. It displays a smooth homogenous illumination of the front side of a backlit part even if a point source light is applied. The surface structure combination of the diffusor film is very fine matte - fine matt. Makrofol® LM309 2-4 160004 is available in standard thicknesses of 300 µm and 500 µm and is offered in rolls and sheets. Typical applications of this polycarbonate film are automotive instrument panels and backlight displays.

We will be happy to advise and consult you in the planning of your project and send you technical data sheets or samples of our plastic films for the construction of initial prototypes. We also offer reflective films (in bright white color) or optical clear films that can be used in combination with a diffusor film. Reflective films can be applied in the rear side to enhance the light in an lluminated surface.

The market for light-emitting diodes in lighting is booming. This is hardly surprising since the LED technology has huge advantages: they consume less energy than incandescent bulbs and discharge lamps and help protecting the environment, and have a much longer service life. If you are designing or manufacturing an LED lighting component for commercial, industrial or residential use, we have the solution you need. We offer a wide range of technical films for the diffusion of light and LED light. These films act as diffusor to avoid that the light source gets visible. In addition to a high light transmission, all our diffusor films show a good heat resistance.

Our translucent polycarbonate films for light diffusion are particularly impressive due to their mechanical strength and impact resistance. In addition, they have a distinct temperature resistance from - 40 °C to 130 °C (continuous operating temperature of 105 °C), a high dimensional stability as well as good dielectric and insulating properties.

The different light diffusion films differ from each other in terms of light transmission (light transmittance), the half-power angle and color. Depending on the application, the light source, we recommend you a material with suitable light values. The surface of the film has a slight glare without being reflective.

The translucent diffusor films impress with their homogeneous diffusion of light and provide an excellent light diffusion. This makes them the ideal solution for a wide range of applications in lighting technology and the lighting industry. The diffusor films are used for spreading light and dividing the brightness and glare over the whole area of the lighting surface. The diffusion can vary from translucent and strongly light-scattering films. We supply you our film diffusor as rolls or sheets. Just tell us the sheet size and we prepare you a competitive quote.

A diffusor film is needed to spread and diffuse the light of the LED over the entire surface of the light surface. Like this no single light sources are visible, but the optical brightness is spread over the whole surface to achieve a perfect illumination.
