Application

It is a high efficient UV absorber, which can effectively absorb 270-400 nm UV light. 

Good thermo stability, low volatility, good intermiscibility with the polyolefin. 

It almost does not absorb visible light, particularly applicable to colorless and light-colored products. 

It is suitable for polyolefin, PVC, PMMA, POM, PU and ABS resin. This product is particularly suited to polypropylene fiber.
