MAXIMA, the hot-melt revolution

Many of you are already familiar with our MAXIMA range of metallocene adhesives. More sustainable, because they are responsibly sourced and designed to be effective and cost-saving throughout their life cycle.

What we would like to explain to you today is where they come from and what they are made of. The generic term "polyolefin" (PO) covers a wide range of materials traditionally used in the adhesives industry.

The word metallocene encompasses a family of compounds usually consisting of two rings of five carbons attached to a transition metal. Its technology is relatively recent: it was in the late 1970s when its importance was recognized in industrial processes as powerful precursors of olefin polymerization catalysts.

However, it was not until 1990 that metallocene technology made a significant impact on the olefin chemical industry. Until then, the production of polyolefins (PO) basically corresponded to Ziegler-Natta type catalysts, with structures of multiple active centres, which gave rise to polymers with wider molecular weight distributions and a wide variety of possible chemical structures.

With the discovery and use of the new metallocene systems, with a structure with a single active centre, a more precise control over polymer synthesis was achieved at an industrial level, allowing a wide range of polymers to be obtained with a strength, hardness and transparency that had not been possible until then.

In the adhesives industry, it is now possible to custom design a polymer with specific adhesion and cohesion along with superior viscosity control. For formulators, this represents a before and after. Advances in technology and the growing range of metallocene POs (mPOs) allow a broad spectrum of products to be formulated with high performance and high stability, ensuring superior adhesion together with reduced adhesive consumption.

For this reason we recommend you try our MAXIMA range.
