LIFOPAL

Transparent plastics with frosted effect

Special additive masterbatches can make highly transparent plastics such as PMMA, SAN, PC, and PET light-diffusing – while avoiding annoying hot spots. The new additive masterbatch LIFOPAL let transparent polymers appear “iced up“, similar to a frosted glass effect. LIFOPAL masterbatches are suitable for light panels, lamp covers, structural panels and profiles as well as for decorative packaging, especially in the cosmetics industry.

Extravagant frosted effects for decorative items The excellent functional and technical properties of the LIFOPAL range are predestined for applications with “cool” frost effects looks, e.g. for decorative items in packaging. Their innovative technology enables a variety of visually extraordinary design variations and individual colour adjustments in unusual pastel shades. Especially glasses, bottles, jars and cans for cosmetics can be produced with special charm, using the LIFOPAL products.

Diffuser effect avoids hot spots on LED lighting The diffuser effect of LIFOPAL creates a soft and homogenous light diffusion across the entire surface while ensuring out-standing translucency. Thanks to these properties LIFOPAL is particularly interesting for the rapidly growing LED market. LEDs have a significantly longer service life and consume significantly less energy than conventional light sources. However, their light is very intense and rigid which is perceived as extremely unpleasant by the human eye. If the light radiation of LEDs is covered by panels or profiles, so-called hot spots occur, i.e. the light radiation is not evenly distributed over the entire surface but is perceived selectively. Sharp contours of the light source are visible. If the light-scattering effect becomes too strong, the opposite occurs. In this case, the plastic component appears darker due to the blocked transmission. Thanks to its unique light diffusion properties LIFOPAL is the perfect solution for the production of technically brilliant LED products.

Diverse production varieties

LIFOPAL offers a wide range of variations depending on the LDR and the base polymer. The presentation folder contains a number of product examples: transparent SAN, PMMA, PC and PET coloured with different percentage of the light-diffusing additive, creating the frosted effect appearance. Light scattering, diffusion and transparency of the plastic item play an important role.

Good processing properties in injection moulding and extrusion

Especially the automotive industry requires the highest precision in the processing of technical plastics. Therefore, car manufactu-rers and suppliers rely on the excellent diffuser properties of our LIFOPAL products: their innovative day-and-night designs use these diffusers to scatter light over a large surface without changing the light spectrum. The optimal balance between trans-lucency and light diffusion creates a unique frost effect. As a positive side effect: processing parameters in injection moulding and extrusion remain unchanged.

A comparison shows the difference

The left sample is produced with a LDR of 12% LIFOPAL in PMMA and the right sample with only 6% LDR in PMMA. The hot spots are blurred, but contours are still recognizable.

Hot spots disappear the higher the LDR and the greater the wall thickness. The transparent sample in the middle contains no LIFOPAL additive; so the LED stripe is clearly visible.
