Use

UV-1577 CAS 147315-50-2 is widely used in various polymer materials as a UV absorber and stabilizer to protect materials from damage by UV radiation. It is particularly suitable for the following polymers:

Polyester

Polycarbonate (PC)

Polyamide (PA)

Polyetheramine

Polystyrene (PS)

Acrylic copolymer

Polymethyl methacrylate (PMMA)

Polybutylene terephthalate (PBT)

Styrene-acrylonitrile resin (SAN)

ASA, etc.

UV-1577 is particularly suitable for some processing and application occasions that require large amount of UV absorber, low volatility and good compatibility, such as complex molded products, flat/corrugated boards, double-wall boards, films, co-injection or co-extruded semi-finished products. In addition, it is also particularly suitable for polycarbonate (PC) films, sheets, plates, etc., with good compatibility with PC, extremely low volatility in high-temperature melt processing, and not easy to precipitate.


Storage and transportation

UV-1577 should be stored in a cool, dry, ventilated place, away from direct sunlight. Please consult the safety data sheet and follow the relevant safety operating procedures before handling or using. If stored in a dry area below 25°C in a proper manner, its shelf life is usually up to one year.


UV-1577 CAS 147315-50-2 is an ultraviolet absorber with excellent performance, which is widely used in the protection of various polymer materials.
