Evonik VESTOPLAST 508 Amorphous Polyolefin

Evonik VESTOPLAST 508 is an amorphous polyolefin (APO) thermoplastic polymer offering excellent tack, heat resistance, and compatibility with diverse substrates. Designed for hot-melt adhesives, it enhances melt viscosity control and open time while maintaining strong adhesion on low-surface-energy materials like polypropylene and PE. Its low odor and high thermal stability support sustainable, high-performance bonding solutions across packaging, automotive, and hygiene applications.
