The Protection of Urethane Bumpers
Protection comes in many forms depending on the context. For a celebrity, the best protection comes from a human-being security guard who has serious training, strength and maybe a gun. Home protection is in the form of small mechanical systems with sensors surrounding the perimeter, which when activated alert the police that someone is on your property uninvited. For moving vehicles, protection served in the shape of a urethane bumper. Bumpers absorb the impact of an accident, protecting the person inside the vehicle as well as the rest of the vehicle from more intense damage. Urethane bumpers are also utilized in machining contexts to protect internal mechanisms from external jolts. Additional industries served include construction and electronics.
Urethane is a popular material choice for bumpers because of a variety of reasons. The broad range of hardness allows manufacturers to develop the exact material they desire by adding or subtracting chemicals from the urethane structure while in its molten state. This is why it can be used as a bumper material in so many different contexts, because it can range from a sturdy foam consistency to a hard and strong plastic. Also, it has high impact capabilities, excellent resistance to corrosion, high abrasion resistance and good load bearing capabilities. Because it is often formed into a shape by way of urethane molding, the substance, also known as polyurethane is able to be produced in a final form quickly efficiently and cheaply.
The one downside to utilizing polyurethane molding techniques is that urethane is a thermoset elastomer and therefore is only able to be melted and formed once. Unlike thermoplastics that can be melted and formed numerous times, polyurethane only gets the one time. However, because it is such a sturdy and reliable substance, urethane bumpers last for very long periods, and can sometimes be reused for other products.
