This company recently introduced new grades of low viscosity Vistamaxx™ performance polymers for hygiene and assembly hot-melt adhesive applications. Vistamaxx 8780 and 8380 grades expand the adhesive application options of Vistamaxx 8880. These three low-viscosity polymers reportedly enable the formulation of high-performance, low-odor, low-density hot-melt adhesives used in packaging, hygiene, and assembly applications. 

These new polymers can provide a range of properties for hot-melt adhesives, including low density for more adhesive mileage. They reportedly enable clean hot-melt formulations with good thermal stability, while offering a broad service temperature range and the ability to tailor high consistent tack with adjustable open/set times. Hot-melt adhesive formulations in which Vistamaxx polymers are used provide a broad processing window, application techniques, and service temperature ranges.

Vistamaxx 8380 and 8780 are designed for hygiene applications that require low-odor, minimal color adhesives. They reportedly enable thermally stable formulations with polymer loadings of 45-65%. Formulators can create hot-melt adhesives that meet open and set time needs while also delivering higher mileage compared to adhesives based on SBC and metallocene polyethylene. This, combined with good adhesion to low surface energy substrates, reportedly delivers added value for diaper and adult incontinence products, as less adhesive is required in the fabrication and lower adhesive use can enable premium attributes like softer touch, better fitting and less bulky products.
