CHEMK UV-1577as a triazine series UV absorber has very low volatility and is highly compatible with polymers and other additives. It is especially suitable for polymers that require high concentration, low volatility processing and good conditions. It can be used with acrylate, PVC, polyester, polycarbonate, styrene, and other high performance polymers. It can make polycarbonate and polyester achieve better weather resistance than traditional UV absorbers. Low chelating trend enables it to be used in polymer formulations containing residual catalysts.
CHEMK UV-1577 is suitable for all kinds of high performance polymers and alloys, such as PET、PBT、PC(linear and branched), polyether ester, PMMA, acrylic copolymers, PA、PS、SAN、ASA, polyolefin, etc., reinforced or not reinforced, filled or unfilled, flame-retardant or non-flame-retardant, transparent, translucent, etc.
CHEMK UV-1577 especially suitable for:
● PC film, sheet, board and so on, good compatibility with PC, low volatility in high temperature melt processing, not easy to precipitate, do not need to wash the runner and mold.
● PA film, sheet, etc.
● PET,PBT film, sheet, board, etc.
● PMMA film, sheet, board, etc.
● Other applications with special requirements for long-term light stability.
