In response to what is polyurethane, we can say; Polyurethane is a synthetic material that is obtained from the reaction between isocyanates and alcohols and has found many applications in various industries due to its unique properties. This material is used in the production of various products, including foams, coatings, insulation layers, household appliances, furniture and even medical equipment, due to its flexibility, high resistance to corrosion, durability and thermal and acoustic insulation.
Polyurethane has become one of the most widely used and essential materials in the modern world, due to its various properties that can be changed depending on the need.
Types of Polyurethane
Polyurethanes are divided into different categories, each of which has its own characteristics and applications. Types of polyurethane generally include soft and hard foams, elastomers, adhesives and coatings. Soft and hard foams are used for insulation and weight reduction in the construction and automotive industries. Polyurethane elastomers are used in the production of automotive parts, sporting goods, and tires due to their high flexibility.
Adhesive and coating polyurethanes are also used to bond various materials and produce durable coatings.
What is polyurethane or polyurethane?
Further to the definition of polyurethane, it should be said that polyurethane is a type of synthetic polymer that is made from the reaction of diisocyanates with compounds containing hydroxyl groups. This material can be produced in various forms such as foam, elastomer, adhesive and coating and is used in various industries including automotive, construction and sports equipment due to its special properties such as durability, flexibility and high resistance.
General properties of polyurethane
The general properties of polyurethane are:
- High resistance to abrasion and pressure
