Negosentro | The Different Uses of Polyurethane | Polyurethane is a versatile material that has become ubiquitous in modern manufacturing. It is made by combining two compounds: isocyanate and polyol, and the resulting chemical reaction produce a material that can be molded into a variety of shapes and sizes. Polyurethane has many desirable properties, including being lightweight, durable, and resistant to impact, abrasion, and weathering. These characteristics have made it an ideal material for use in a wide range of applications, from automotive parts to building insulation. Continue reading for a guide on the uses of polyurethane.
Bollards
One common use for polyurethane is in the manufacture of parking bollards. Parking and street furniture bollards are designed to protect cars and buildings from accidental collisions. They are often made of a combination of steel and polyurethane, which provides both strength and impact resistance. The polyurethane coating also helps to protect the bollard from damage due to weathering and exposure to the elements, meaning that bollards are typically expected to last a long time before being replaced by local government staff.
Roller Coaster Tracks
Due to its high strength-to-weight ratio, another application of polyurethane is in the construction of roller coaster tracks, which must be able to withstand high speeds, G-forces, and sudden changes in direction. Additionally, polyurethane is resistant to impact, which is essential for a roller coaster that may be exposed to flying debris.
Furniture
Polyurethane is also commonly used in the manufacture of furniture. Polyurethane foam is used as a cushioning material in chairs, sofas, and mattresses. The foam provides a soft, comfortable seat, while also being durable enough to withstand regular use.
Polyurethane can also be used to create decorative accents on furniture, such as carved moldings and ornamental details, as its synthetic nature makes it easier to mold than alternative natural equivalents.
Vehicles
Numerous uses for polyurethane have been found in the automotive industry. It is used in the production of various components such as seats, dashboards, steering wheels, and interior trims. The material provides superior durability and strength, making it ideal for use in these applications.
Polyurethane is also used in the production of tires, where it is formulated to provide excellent grip and wear resistance. It is a critical component in the manufacturing of suspension bushings, which help dampen noise, vibrations, and harshness (NVH) in the vehicle.
Polyurethane is also used in the production of body kits, spoilers, and other exterior components that require high strength and durability. For example, it is used in the manufacture of car bumpers, which must be able to withstand impacts from crashes while also being lightweight enough to reduce the overall weight of the vehicle.
The automotive polyurethane market is extremely valuable, with more sustainable alternatives being developed by plastics companies.
Construction
Finally, polyurethane is used in the construction industry. It is used as insulation in walls, roofs, and floors. Polyurethane insulation has a high R-value, which means that it is an effective insulator that helps to keep buildings warm in the winter and cool in the summer. Polyurethane is also used as a coating on concrete surfaces, which helps to protect them from general wear and tear.
