• Application of UV Absorber UV-3638 CAS:18600-59-4

  UV-3638 provides very powerful and broad UV absorption without color smearing. Very good stability to polyester (PET) and polycarbonate (PC). Based on the benzoxepanone structure, 3638 offers short-term thermal stability up to 350°C and long-term thermal stability up to 160°C. TGA (10%) is greater than 371 degrees Celsius. For thermoplastic polyester, nylon, and defense industries with high processing temperatures and stringent requirements for UV absorption. High molecular weight, low volatility, no color stain. It is especially suitable for the optical industry that requires light transmittance and color, such as PET, PC optical material lenses, light diffusing plates for backlight liquid crystal display devices, etc.
