Pearlcoat® Activa D118K is a special copolyester based thermoplastic polyurethane of low hardness, supplied in form of natural pellets. This product gives an inherent "low gloss aspect" on the final product surface after extrusion processing. Featuring low gel content as well as low-temperature flexibility, it is ideally suited for extrusion or co-extrusion onto polar substrates.
Pearlcoat® Activa D118K is ideally used for extrusion, co-extrusion onto polar substrates applications where low gloss aspect is required.
