Invented back in the 1930s by Professor Dr. Otto Bayer, polyurethane (PU) or urethane is an elastomeric material available in a wide range of hardness from eraser soft to cricket ball hard.

There are different types of polyurethanes, used in a diversity of products from coatings and adhesives to shoe soles and mining components. However, the basic chemistry of each type is essentially the same.

Widespread use of polyurethanes was first seen during World War II, when they were utilised as a replacement for rubber, which at the time was expensive and hard to obtain. Over many decades other applications were developed and today it would be hard to imagine industry without this material.

Among many applications, we came across an interesting one in Australia, country blessed by many sandy beaches.

Industrial beach sweepers are equipped with polyurethane pads which assist the process of cleaning and flattening the sand. These parts use the excellent resistance of polyurethane to abrasion, oils, various chemicals, solvents, and oxidation while maintaining high tensile strength and resilience.

In addition, polyurethane provides great impact resistance and high load bearing capacity making it one of the best materials for heavy duty and large scale jobs.

It is also interesting to know that the polyurethane family is under continuous development towards more environmental friendly solutions, opening new doors to eco-sensible and efficient solutions for our planet.
