The use of VESTOPLAST® as main polymer in packaging hotmelt adhesives provides a balanced profile of excellent adhesion performance on different subtrates, adjustable open time and an improved hot tack compared to EVA. A very good flexibility and grades with different stability under thermal stress enables our customers to adjust the adhesive properties according to their requirements.
VESTOWAX® straight chain Fischer-Tropsch hard paraffins reduce the viscosity of EVA- or metallocene catalyzed polyolefin- based packaging hotmelts and therefore ensure efficient mixing of polymers and resins and facilitate even surface wetting of the substrates. Furthermore, the high crystallinity of Fischer-Tropsch hard paraffins is used to regulate open- and setting-time. Finally, the addition of VESTOWAX® reduces the surfaces tackiness of hotmelts ensuring better storage stability.
