EVONIK VESTOPLAST®
VESTOPLAST® grades are amorphous poly-alpha-olefins
produced with three monomers - ethylene, propylene and butene-1. It is mainly used as a raw material for hot melt adhesives that are applied within several industries like hygiene, automotive, packaging and woodworking.
All VESTOPLAST® grades are produced to specification in a continuous Ziegler low-pressure polymerization process. Based on the special process, they have excellent properties, mainly reflected in hardness, cohesion, melt viscosity, crystallinity, crystallization rate and lower density about 0.86g/cm3.
