SperseStab™ 3360

1 of 26 products in this brand
SperseStab™ 3360 is a very low-volatility benzotriazole UV absorber designed for use as a light stabilizer in a variety of plastics. Its low volatility makes it ideal for use in engineering plastics and fibers processed at high temperatures. With high molecular weight, low blooming, and minimal plateout in PC and other polymers, including PET, POM, PBT, PMMA, and polyamides, it is an ideal choice for co-extrusion multi-layer applications.

Functions: Light Stabilizer, Stabilizer, UV Absorber

Compatible Polymers & Resins: Poly(Methyl Methacrylate) (PMMA), Polyamides, Polybutylene Terephthalate (PBT), Polycarbonates (PC), Polyethylene Terephthalate (PET), Polyolefins, Polyoxymethylene (POM)

Processing Methods: Coextrusion, Lamination
