What is polyurethane resin?
Polyurethanes are a highly useful family of polymers – materials that result from the linking of a chain of simple, repetitive molecules. These materials can appear in many forms and be used for a variety of things, depending on the way their properties are manipulated. Polyurethane resin, a synthetically-produced substance, is one of the forms polymers appear as.
Polyurethane resin is very versatile because it can be used to produce a range of items, such as inks and plastics. This is possible because the material can be manipulated greatly, changing its properties such as hardness and elasticity. Often, it is produced in liquid form and can be poured into moulds. When used in this way, the material is very impressionable, meaning the slightest detail, such as a small crack, can be seen in the finished product.
There are many advantages to these resins. They are often used for their chemical, oil and grease resistance, and are typically good at resisting abrasion and, therefore, are not easily torn. This explains why they are often used to produce synthetic rubbers. Furthermore, they can be used to create strong adhesives.
