Polyurethane is a synthetic polymer that is formed by the reaction of two chemicals called isocyanate and polyol. This polymer has a wide range of properties and applications, which has made it a versatile and widely used material.
Some properties of polyurethane are:
Durability: Polyurethanes are resistant to wear, corrosion and other environmental factors.
Flexibility: Polyurethanes are resistant to bump and pressure.
Resistance to chemicals: Polyurethanes are resistant to a wide range of chemicals.
Thermal and sound insulation: Polyurethanes are good thermal and sound insulation.
Washable: Some polyurethane applications are washable.
Polyurethanes are used in a wide range of industries, including:
Construction industry: Polyurethanes are used in construction for thermal and sound insulation, floor and wall coverings, adhesives and sealants, prefabricated floors and plasters, mastics, cabinet making, painting, etc. .
Transportation industries: Polyurethanes and automobile manufacturing have created various capacities for manufacturing seats, dashboards, sound insulation and other parts.
Clothing industry: Polyurethanes are used in clothing to make sports clothes, waterproof clothes and other products that use elastic threads with low weight and high resistance.
Furniture industry: Polyurethane foams, also known as flexible furniture materials, are used in furniture to make mattresses, pillows, and other products, and some polyurethane adhesives are used in the furniture industry.
Medical industry: Polyurethanes are used in medicine to make implants, prostheses and antibacterial implantable parts in the body, antivirus filters and fast-acting sutures and other such products.
Packaging industry: Polyurethane also has various uses in the packaging industry. Packaging using polyurethane is used in these industries due to features such as mechanical resistance, flexibility, waterproof properties and thermal insulation properties.
Electronic and electrical industries: Polyurethane is used in the production of electronic and electrical parts such as cases, cables, bumpers, sockets and terminals. This material is very welcome in these industries due to its electrical properties and resistance to shock and mechanical vibrations.
Sports and entertainment industries: Polyurethane is used in the production of sports equipment such as balls, boots, impact bags and indoor sports surfaces. This material is very suitable in the production of sports equipment due to its flexibility, wear resistance and waterproof and anti-shock properties.
Pu materials exist in different types, which have different properties and applications according to the type of isocyanate and polyol used.
Rigid polyurethanes: These rigid polyurethanes have a block structure and have properties such as resistance to wear and impact, strength and high durability. These polyurethanes are used in applications such as flooring, protective coatings, polyurethane spray foams, prefabricated polyurethane plasters, cabinet making, etc.
Soft polyurethanes: These flexible polyurethanes have a network structure and have properties such as flexibility, impact resistance and comfort. These polyurethanes are used in applications such as mattresses, pillows, chairs and polyurethane sheets, sports flooring and shoe soles.
Polyurethane foams: These polyurethanes have a porous structure and have properties such as heat and sound insulation, wear and impact resistance. These polyurethanes are used in applications such as heat and sound insulation, furniture and vehicles.
Polyurethane glue: Polyurethane glue is a very strong and durable glue that is used to connect different materials such as wood, metal and plastic.
Polyurethane resin: Polyurethane resin is a coating material used to protect surfaces against moisture, scratches and wear.
Polyurethanes are a versatile and widely used material used in a wide range of applications. The diverse properties and applications of this polymer have made it one of the most widely used polymers in the world.
