Polyester polyols for polyurethane adhesives

Polyurethane adhesives are highly specialized products with a broad range of potential applications. Depending on the desired physical and chemical characteristics, they are used in industries such as mining, and are also popular in hot-melt glue sticks, which are melted at high temperatures.

To achieve the desired specifications of polyurethane adhesives, the selection of appropriate polyester polyols is crucial. Their molecular weight and hydroxyl number influence properties such as viscosity, melting temperature, cross-linking, and other physical attributes.

Polyester polyols for mining adhesives

Specialized and technologically advanced polyester polyols are used in the production of mining adhesives. These are products for specific applications, and therefore, the final product should be not only excellent in terms of quality but also offer consistent parameters.

The mining industry commonly uses polyurethane adhesives to enhance safety and streamline operations. Mining adhesives are primarily responsible for stabilizing rock formations. Stabilizing and reinforcing rock mass, as well as filling gaps, significantly reduces the risk of rockfalls. Another function of polyurethane-based adhesives is to secure structural elements.

With appropriately selected polyester polyols, it is possible to achieve the desired physical properties, including proper mechanics, strength, flexibility, and resistance to various factors, including moisture and vibrations. Adhesives produced based on our polyols are odorless, which is very important underground. Instead, they contain up to 45% of components derived from recycling and biological sources.

Polyester polyols for hot-melt adhesives

Polyester polyols are both highly specialized chemical intermediates and are used to produce adhesives that have a wide range of applications in everyday life. High-quality polymers serve as the base for hot-melt adhesives.

Hot-melt adhesives owe their properties to the appropriate composition of polyols. These are responsible for the key characteristics of the adhesives, including strength, melting temperature, solidification, and health impact. The high standard of polymers offered by our company also translates into the quality of crosslinking and adhesion in challenging conditions.

Adhesives produced using our polyols are widely used in households for quick and easy bonding of elements. They have gained even greater recognition in the furniture industry, where they are used to bond laminates with wooden boards. Excellent adhesion allows them to be used in affixing coverings to pipes. The lack of odor and low allergenicity make hot-melt adhesives increasingly significant in the medical industry.
