Priplast™ 3238
Priplast 3238 is an amorphous polyester polyol (MW 2000) for bio-based polyurethane systems. This liquid and versatile building block is for use in polyurethanes systems such as adhesives, polyurethane dispersions, sealants and elastomers. Priplast 3238 provides extreme hydrophobicity, excellent colour and enhanced durability. It also brings good wetting properties, adhesion to various substrates, including low polarity plastics, and prevents cracking. Priplast 3238 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.
