Toray Launches a 50-Micrometer-Thick Version of PICASUS Nano-Multilayer Window Film Boosting Heat Shielding by 40%

Toray Industries, Inc., today announced that it has launched a 50-micrometer-thick version of PICASUS™ IR (see note 1) film for windows. This nano-multilayer film delivers exceptional transparency and heat shielding.


A push for energy-saving solutions and rising summer temperatures have boosted demand for high-performance heat-shielding window films. Demand is particularly robust for films delivering superior heat shielding and high transparency, as they preserve the aesthetic appearances of buildings and views within rooms while ensuring clear visibility for automobiles.


Toray refined its proprietary nano-multilayer technology, which can layer hundreds to thousands of ultra-thin polymer layers, to develop PICASUS™ IR, and deployed it for factory-installed automotive front windshields and sunroofs.


Toray developed a 50-micrometer film type for PICASUS™ IR for aftermarket building and vehicle applications. This 50-micrometer standard type offers significantly better transparency and heat shielding than conventional heat-shielding window films. Furthermore, the nano-multiple polymer layers deliver exceptional adhesion between each layer, making it easier to rework during installation than commercial products with the same level of heat shielding.


To meet the demands for improved heat shielding performance, Toray is expanding the lineup with a high heat insulation type that maintains high transparency while enhancing heat shielding by 40% compared to the standard type. (note 2) Customer evaluations of this high heat shielding type are also becoming more prominent.

Comparisons of standard and high heat shielding films as stated in the picture.


PICASUS™ IR applications encompass diverse new and existing buildings. This film also matches the high transparency standards of automotive windshields and provides excellent radio wave transparency, overcoming 5G communication issues associated with some metal sputtering technologies, thus ensuring driver safety and comfort.

Toray will keep leveraging its core technologies of synthetic organic and polymer chemistry, biotechnology, and nanotechnology to pursue R&D into groundbreaking materials that can transform the world in keeping with its enduring commitment to delivering new value and contributing to social progress.


Notes

1. PICASUS™ is the collective name for polyester films that leverage Toray’s proprietary nano-multilayer technology. The PICASUS lineup includes metallic luster films that uniformly interfere with and reflect light from visible to near-infrared rays, films that can cut blue light from displays without coloring them, and dichroic films that selectively reflect specific colors.


2. Toray evaluated heat shielding with the Total Solar Energy Rejected index, which measures the film’s ability to block the sun’s radiation.

Today's KNOWLEDGE Share Researchers Identify Plastic-Degrading Microbes in Mangrove Soil An international team of researchers has developed a novel method to select bacteria from mangrove soils capable of transforming plastic. This breakthrough offers a potential new approach to tackling plastic waste pollution. By analyzing the effects of polyethylene terephthalate (PET) particles and seawater intrusion on the microbiome of mangrove soil, the team was able to cultivate a collection of PET-degrading microbes. With plastic pollution reaching alarming levels globally, even in remote ocean environments, ecosystems like mangroves—crucial biodiversity hotspots—are under threat from various stressors, including plastic contamination. “Mangrove ecosystems are exposed to significant plastic pollution, and their soils harbor diverse microbial communities, including those with potential plastic-degrading capabilities,” explained Diego Javier Jiménez Avella, a research scientist from the Micr...
