Teijin's UV-A transparent weather-resistant polycarbonate is an innovative material that transmits UV-A wavelengths of 330 nm or more while providing excellent weather resistance. It combines ease of processing with high impact resistance, making it suitable for a wide range of applications, including medical equipment and industrial filters.

• About UV-A

  UV-A (ultraviolet A) is an ultraviolet ray with a wavelength of approximately 320 to 400 nm. There are three types of ultraviolet rays: UV-A, UV-B, and UV-C. UV-A has the longest wavelength and accounts for about 90% of the ultraviolet rays that reach the earth's surface. UV-A is used in a variety of fields.

• Nondestructive testing：Black lights that utilize UV-A are used for non-destructive testing such as fluorescent penetrant testing and fluorescent magnetic particle testing. This allows for the detection of cracks particle testing.
• UV curing：A technology that uses UV-A to harden special resin materials. It is used in nail art, hardening dental materials, and hardening photoresists in the semiconductor manufacturing processes.
• Medical：UV-A is also used for skin treatment. e.g., treating psoriasis and atopic dermatitis.
• Sterilization and disinfection：UV-A is not as powerful as UV-C, but it can still be used for sterilization and disinfection under certain conditions.
• Insect lamp：UV-A has the property of attracting insects, so UV-A lamps are widely used in insect traps and insect lamps.
