²What is infrared ray?
Infrared ray is a kind of electromagnetic wave, with the wavelength between visible light and microwave, ranging from 760nm to 1000 μm. It can be roughly divided into the following different wave bands:
Near infrared band (760 nm-2500 nm)
Mid-infrared band (2.5 μm-25 μm)
Far infrared band (25 μm-500 μm)
Near infrared band is often used for remote signals of household appliances; the mid-infrared band is often used to detect the temperature change of the device surface; the far infrared band is often used for infrared thermography for heat detection. In general, infrared ray has many uses. Whether for remote control or other modern science and technology, infrared ray plays a vital role in the internet field with its high security and convenience.
²How does OMNISTAB NIR Absorber work and what can be applied for?
1. NIR Absorber is the key substance to shield near infrared rays, and is mainly used in various "absorptive thermal insulation film" and "solar film".
Most cars have problems of thermal insulation every hot summer. The heat coming from the car is unbearable when we open the door. And it is difficult to cool down quickly even if the air conditioner is turned on. This is due to the fact that most of the front windshield and window glass of cars are colorless and transparent tempered glass, which have low reflectivity of infrared rays, neither heat insulation in summer nor warmth preservation in winter. Therefore, these windows can not provide a comfortable environment for passengers.
Then, how to solve this problem？
The film material added with OMNISTAB NIR Absorbers can shield the near infrared rays, reduce heat exchange between indoor and outdoor through the glass, and thus reduce the energy consumption of car. This kind of films are playing an important role in saving energy and maintaining comfortable interior temperature. OMNISTAB NIR Absorbers have been widely applied in thermal insulation films and coatings, which can maintain not only the light transmittance and lighting effect of the window but a comfortable environment.
vOMNISTAB® NIR1050
OMNISTAB® NIR1050 is a dark green viscous liquid and can effectively absorb 850nm-1300nm near infrared rays. It has many advantages, such as high compatibility with most resins, high thermal resistance, and good stability.
We can also supply PC master-batch product, OMNISTAB® NIR1050 MB. It can satisfy various plastic processing such as injection molding.
vOMNISTAB® H-6
OMNISTAB® H-6 is a blue dispersion and can effectively absorb near infrared rays in 800-1200nm. It can be applied to films and sheets such as PC, PMMA, PET, etc, with characteristics of good dispersion and high transparency.
1. Another major use of NIR Absorbers is near infrared anti-counterfeiting ink.
The near infrared anti-counterfeiting ink contains one or several NIR Absorbers and can absorb near infrared rays in 700nm-1100nm. If the anti-counterfeiting product prints this kind of ink, the special patterns can be observed under the irradiation of the detection instrument, although there is no trace under the sun.
The near infrared anti-counterfeiting ink has the advantages of strong anti-counterfeiting, convenient use and detection. Its application is almost independent of any printing conditions, so it can be widely used for anti-counterfeiting printing of bills, securities, trademarks, commemorative coins, etc.
vOMNISTAB® NIR788
NIR788 is especially suitable for anti-counterfeiting ink. It has a narrow absorption range and high absorption rate. Products with NIR788 will show a high sensitivity during detection.
vOMNISTAB® H-3
H-3 is a dark green powder, which can absorb near infrared rays in 750-1050nm. Its peak absorption is 975nm and it has strong light and thermal resistance.
