Priplast™ 1900
Priplast 1900 is an amorphous polyester polyol (MW 2000) which meets the demand for improved moisture barrier protection, chemical resistance and hydrolytic stability in application areas where PTMEG and adipate polyols are commonly used. In PU systems this di-functional polyol brings good adhesion to a wide range of substrates, such as metal, wood, PC, PVC, PA and ABS, and is therefore suitable for lightweight applications and furniture. *Priplast 1900 is an ISCC PLUS certified product which is truly bio-based. The vegetable oil bio-based content comes from sustainable ISCC certified sources (mass balance), supporting the sourcing of sustainable vegetable oil.
