|---|
| PEARLCOAT® Activa D198K is an aliphatic based thermoplastic polyurethane of low hardness, supplied in the 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.&& |
