High density polyurethane parts: strength and durability

Piezas de poliuretano de alta densidad

Polyurethane systems are widely used in different sectors ranging from construction to medicine. We can find polyurethane systems in seats, housings, technical laboratory equipment, armrests, headrests, rims, and even in the adhesive joints between different pieces.

Polyurethane is a very strong material. This and other properties such as adaptability have been key, for example, in the development of the automotive industry that incorporates high density polyurethane parts in vehicles to make them more efficient and sustainable. In fact, nowadays, the incorporation of polyurethane inside the vehicles supposes around 15-20% of the total of plastics used in the manufacture of automobiles.


Properties of High Density Polyurethane Parts

The increasing industrial use of high density polyurethane parts is mainly due to two properties: durability and versatility. Polyurethane is one of the materials with the greatest number of application and innovation possibilities.

The durability of the polyurethane guarantees the maintenance of its performance throughout the life of the product. It is a material that resists to atmospheric agents (water, sudden change of temperatures, wind …) and mechanical actions such as punctures, friction or pressure, which makes it one of the best options for industry. 

Manufacture of high density polyurethane parts

Thanks to the ease of molding high density polyurethane in its manufacturing phase, high density polyurethane parts are manufactured in industries as different as the automobile or the manufacture of electrical appliances.

The most common method of manufacturing high density polyurethane parts is through the injection of polyurethane into molds. The molds for polyurethane parts have undergone great advances that allow to obtain a final polyurethane piece with almost no need of retouching it: the final product is taken out of the mold with the desired shape.
