Film for shaping / diffusing light

Makrofol® LM 297

Makrofol® LM 297

Makrofol® LM297 H-M 040007 is a lens type light shaping film that has been designed especially for LCD backlight applications. It is an extrusion film with anti-dust feature based on Makrolon® Polycarbonate resin from Covestro. The embossed lenticular lenses unite the individual light spots of LEDs. The deployment of two layers in perpendicular orientation to each other delivers full diffusion and de-glaring. Its unique polynominal structured surface (H-surface) ensures high-end performance regarding homogenization, transmittance and processability. The surface structure of the reverse side is fine matte (M-surface). Makrofol® LM297 H-M 040007 is available in standard thickness of 280 µm. Other thicknesses are available on demand. Typical applications of this polycarbonate film are televisions, monitors and backlight displays.

Film for the direction and diffusion of light

As an expert for technical films, the König Film Centre offers you numerous solutions for lighting applications. In recent years, we have compiled a range of special films for lighting technology. In addition to light diffusion films and reflector films, this range includes a light shaping film.

This is a lenticular film made of polycarbonate called Makrofol® LM 297 H-M 040007 from the German manufacturer Covestro.

Covestro is one of the world's leading manufacturers of polycarbonate films. The German company's products and application solutions can be found in many areas of our lives. With its Makrofol LM films, Covestro is particularly strong in the field of high-quality solutions for lighting technology.

The translucent light diffusion films impress with their homogeneous diffusion of light and illumination. This makes them the ideal solution for a wide range of applications in lighting technology and the lighting industry.

What is a lenticular film?

Makrofol® LM297 H-M 040007 is a lens type light shaping film that has especially been designed for LCD backlight applications. It is an extrusion film with anti-dust feature based on Makrolon® polycarbonate resin from Covestro. Its unique polynominal structured surface (H-surface) ensures high-end performance regarding homogenization, transmittance and processability. The surface structure of the reverse side is fine matte (M-surface).

Applications of light shaping films

Typical applications of this polycarbonate film are televisions, monitors and backlight displays. The film is also suitable for the following uses:

  • Uniform diffusion of LED light.
  • Backlit displays, indicators and switches.
  • Backlit interior parts for automobiles.
  • Diffusion of light from different light sources.

Properties

As a polycarbonate film, Makrofol LM 297 impresses above all with its high mechanical strength and impact resistance. In addition, it has a pronounced temperature resistance from - 40 °C to 130 °C (continuous service temperature of 105 °C), high dimensional stability and good dielectric and insulating properties. The plastic film is suitable for a wide variety of lighting applications and for ideal light distribution. Our light directing film is also suitable for special applications such as thermoforming or high-pressure forming. The film can be processed without special accessories.
