Polyurethane is known to the older generation due to its durability. In the past, it was used to stuff the heels of women's shoes. Due to the lack of experience in their production, polyurethane bushings https://polypro.com.ua/en/ of stabilizers initially received a bad reputation. So, the "oak" bushings manufactured by some entrepreneurs were (are) the cause of a number of shortcomings:
accelerated abrasive wear of the stabilizer shaft at the place of landing of the bushings;
transmission of large shock loads to the body and suspension parts;
the source of unpleasant squeaks.
That is why it is necessary to choose bushings of stabilizers, which have characteristics close to rubber products. One of the main parameters of stabilizer bushings is the hardness of the material (or, as they often say, elasticity or stiffness). Preservation of the elasticity of the stabilizer bushings is a guarantee of maintaining the level of comfort of the car and the durability of the stabilizer struts and other hinged elements of the car suspension.
The color of polyurethane parts has nothing to do with their properties. Polyurethane itself is cloudy and transparent with a yellow-brown tint. Polyurethane bushings of stabilizers of yellow, red, green and other colors available on sale can have the same properties, since the dye does not affect the properties of this material in any way.
In addition to the hardness, polyurethane products can differ in durability, which depends on the preparation of this material, including the number of components. Our stabilizer bushings are filled with three-component polyurethane, the composition of which is maximally oriented to a long service life without negative effects.
