Product: COMFOGUARD UV-002, 008, VIS-001
<Base material: ulethane resin, polycarbonate resin>

Feature Points : Bluelight*1 block and keep the object less-colored at the same time

  • *1 Bluelight (380 to 500nm) is emitted by smart phone, PC LED display and LED light. It has strong energy and concern for health.

<Influence of bluelight for health>
[image] Bluelight entering through the eye and reaching Macula part of eye

A. 400 to 420nm: Causes oxidative stress in Macula of the retina.
This is one of the factors of age-related macular degeneration (the leading cause of blindness in Europe and the United States).

B. 460~480nm: Restrain the emission of melatonin (known as dormancy hormone), which cause sleeping disorder.

Prevention of skin sunburn and wrinkle (For Automobile front side glass)

Product: COMFOGUARD UV-011
Base material: Glass

Feature Points: DeepUVA (UVA of 370 to 400nm) block. Can be utilized as glass coating.

Prevents incoming insects. The less-colored material improves visibility, which brings high efficiency to indoor desk work.

Prevent degradation of Food and Medical drug (Packaging film)

Product: COMFOGUARD UV-002, 008, VIS-002
Base material: PET resin, polyethylene resin

Feature Points: 1) Block up to 420nm, 2) 400 to 480nm block and keep the object less-colored at the same time.
