Blog → Hardness and color of polyurethane. is there any connection between them?

If it's time to replace the bushings in your suspension and you decide to switch from rubber to polyurethane, how do you choose what you need? Someone advises to choose parts of a certain color because he heard good reviews about them. But focusing on the reputation of the manufacturer is much more important.

It is also important to take into account the design features of a particular car when choosing polyurethane bushings and bushings, because even cars of the same brand, but different years of production, may differ.

Therefore, here are some general recommendations that will help you find the right spare part.

1.  Choose polyurethane consumables with the correct hardness. Polyurethane can have different stiffness like rubber: be soft and easily deform, or hard like plastic. It depends on the purpose of its application and the method of manufacture. A sports car needs tougher parts. A passenger car needs polyurethane with a hardness 65 A according to Shore, like rubber.
2. Don't rely on color. The quality and strength of polyurethane don't depend on its color. This material is light, and products of any hardness can be given the color that the manufacturer wishes. Therefore, the opinion that, for example, yellow bushings or bushings are better than blue ones, can lead to disappointment from the purchase. Focus on the reputation of the manufacturer, which will help to find out the corporate color of its products.
3. Pick the right size. The key to long and reliable operation of polyurethane spare parts is the selection of the right size and proper installation. When you order a part, consider the degree of wear of the structure or assembly, as well as the type of silent block with or without a cage. Therefore, don't always blindly rely on part numbers and part sizes, especially if you are not the first owner of the car. You may need advice from an auto mechanic.
