Frozen food labeling and packaging is a real challenge when formulating with high Tg polymers like SIS.
Indeed, adhesives have a brittle consistence, losing most of their properties under the Tg of polymers and tackifiers used in their formulation.
That's why, to perform at frozen temperatures, it is very important to select the right polymer and tackifier in the adhesives' formulation.
Dynasol has developed its own hydrogenation technology for SEBS copolymers production. This novel technology allows adhesive formulators to achieve polymer saturation levels superior to 99%, this means polymer stability to UV and ozone light attack and superior than other technologies in the market.
Superior UV light resistance & improved adhesive cohesion
Develop best in-class PSAs & get improved productivity thanks to SBC multiarm polymer.
In order to offer additional alternatives adhesives formulators to reach a wider range of adhesive / viscosity properties balance, Dynasol has recently developed a novel structure with a multiarm architecture.
Formulators have now the possibility to use solutions based on the comprehensive range of SBS / SBS multiarm polymers. It covers from partial to full substitution of SIS with no major change on formulation.
The Dynasol technical team strongly versed in the SBC field has successfully developed sprayable adhesive formulations with high solids content while obtaining a low viscosity, a quite uncommon duality in today's standard.
Dynasol has developed the last SSBR generation, Solprene® 1217. Because of its multiple advantages, hot-melt formulators can now overcome soft points of other conventional polymers on the market place.
Labeling is a high throughput application where any increase in application speed may represent a gain in productivity, and so in profitability. Dynasol latest development leads to this improvement, making the tack properties allowed by Solprene® 4302, faster than conventional commercial polymer reference.
Dynasol Solprene® 4301 is preferred to formulate HMA because it allows to improve cohesive strength. Fomulated with Solprene® 4318, adhesive viscosity can be reduced. As a result, the temperature required for the application is lower, improving adhesive set time, and the productivity.
