In recent times, plastic resins have gained immense popularity over other materials. This is all due to their typical characteristics such as excellent moldability, easy availability, versatility, and many more. There are various types of plastic resins in use today and urethane resins are one of them. Urethane resins are increasingly used at various applications that demand durability and reliability. But, what makes it so popular? This post emphasizes on urethane resins in detail. So, stay tuned to know more.
An Overview of Urethane Resins
The urethane resin, which is commonly known as polyurethane, is well-known for its versatility. These resins are created through polymer addition of polyols or dialcohols and polyisocyanates. They have great adhesive qualities and offer high elasticity, too. As these resins are less brittle and thinner than polyester, they are ideal for applications such as coating, films, fibers, and metal treatment.
Many urethane resins are specially formulated to meet specific application requirements. Therefore, not only thermoplastics, thermosets, and elastomers are produced from it. The mechanical properties of these resins can be altered using polymeric reactions, which makes it purposeful with high-performance ability.
Why are Urethane Resins Popular?
The following beneficial features of urethane resins have contributed to their use across various industries. So, let’s have a look at it.
- Excellent Flexibility: Urethane resins are popularly known for their excellent flexibility. Their lightweight characteristics make them an ideal choice for a variety of applications. These resins can withstand high flexure and fatigue, which is why they are used in a variety of heavyweight and lightweight applications. Although flexible and lightweight, they never lose their strength and durability.
- Excellent Resilience: This is the utmost beneficial feature of this resin. Polyurethanes can withstand noise, weather, and other environmental impacts. They possess high tear resistance and excellent tensile properties, too. All these features make urethane resins an ideal choice for both indoor and outdoor applications. Urethane works well even at low temperatures, which makes them ideal for applications where managing wear and tear due to temperature variations can be difficult.
- Strong Bonding: Polyurethanes can be easily mixed and processed, owing to their excellent flow characteristics. Thus, it can be bonded to a wide range of materials, including wood, metals, wood, and other types of plastics. This property makes it an ideal choice for rollers, inserts, and wheels.
- Environmental Friendly: Over the years, environmental consciousness has increased. There have been concerns about the increasing use of plastics and their toxic effect on the environment and human lives. This is where urethane resins make a difference. They are used in water-based coatings, which contain little or no volatile organic content. This helps ensures the safety of areas where they are used. Similarly, nowadays, chemical engineers are altering the formulation of urethane resins to improve their utility and acceptance.
Applications of Urethane Resins
Here are some important used of urethane resins:
- Automotive: Urethane resins are used in automobiles. From car ceiling, body, doors, car seats, bumpers, windows, you will find this material in the form of foam. The foam is well-known for its vibration resistance and soundproofing capabilities. This lightweight material helps improve the fuel economy, as well as improve the comfort of car users.
- Construction: Today’s home demands performance-driven materials that are lightweight strong, durable, and versatile. Owing to their insulation properties, excellent strength, and durability, they are widely used in several building and construction projects in different forms.
- Electronics: Also called potting compounds, non-foam urethanes are used in electronics and electrical industries for compressing and insulating PCBs, underwater cables, and small components that may give up under pressure and temperature. They also help improve the resistance of electronic components against water, temperature, and so on.
- Flooring: Polyurethanes are used in several residential and commercial buildings to increase the lifespan of the floor. They help make them maintainable, sturdier, and lasting. It is also used to coat floors, as strong protection from scuffing and solvents.
- Medical: Urethane resins offer advantages of toughness, flexibility, affordability, and lightweight. Hence, it is effectively used in several medical equipment and accessories including implants, hospital bedding, wound dressings, surgical drapes, numerous injection molded devices, and so on.
