The innovation has been achieved by working closely together with DOW, a leading materials science company, and targeted to achieve a highly efficient as well as environmentally friendly outcome.
One of the key features of this technology is its excellent processability, being sprayed at low temperatures with no angel hair formation.
A crucial aspect for this performance is the use of an adhesive that is based on olefin block co-polymer technology from Dow offering a wide operating window suitable for spray and slot applicators.
The lower density of this technology and higher adhesion properties enables to reduce the glue consumption by up to 20%. Using less material to achieve enhanced performance has a positive impact on the carbon footprint of these applications and, ultimately, on the environment.
“Sustainability is a key driver in the evolution of the hygiene market. From the very beginning of this project, the aim to develop a more sustainable solution was identified as a key priority. The enhanced performance of this product is of great importance for us, matching the ever-evolving needs and demands of our clients. Our focus remains the same: to provide the market with highly efficient, safe and sustainable solutions”, says Igor Encarnação, Colquímica Adhesives Procurement Manager.
“Building on Dow’s polymer and Colquimica’s formulation expertise, we’ve delivered a concrete and market-relevant polyolefin-based solution which will help manufacture more sustainable hygiene products without compromising on performance,” comments Imran Munshi, Global Market Segment Leader for Hot-Melt Adhesives at Dow.
“In our aim to support and advance the market needs for resource-efficient, mono-material and circular solutions, innovation like Colquimia’s new adhesive will lead the way to a more sustainable industry.”
Colquímica Adhesives and DOW are already working together on new projects and both maintain a strong focus on innovation as a key element to provide the hygiene market with green, high-performance technology.
