Amorphous Poly-alpha-olefins: With its VESTOPLASTR amorphous poly-alpha-olefins (APAO) Evonik offers a broad range of co- and terpolymers of ethene, propene and 1-butene as raw materials for various applications. Under variation of monomer composition, molecular weight and chemical modification optimum values are achieved for properties like hardness, melt viscosity, crystallinity and rate of crystallization. The production process allows us to offer both predominately amorphous, soft grades as well as harder, partially crystalline grades. In addition to our regular, pure thermoplastic grades we also offer unique reactive, silane-modified amorphous poly-alpha-olefins like VESTOPLASTR 206. VESTOPLASTR is usually supplied as granules in 20 kg polyethylene bags. A special wax powdering technique improves the flowability of the material. Your benefits:- excellent adhesion and hot tack properties
- bonding to various substrates
- good cohesion and high thermal stability
- good moisture and gas barrier behaviour
- very good hydrolytic and UV stability
