Where polyurethane parts are used

Among the main components in a vehicle suspension where polyurethane materials are used, the following can be выделены:

• Control arm bushings for front and rear suspension
• Anti-roll bars and silent blocks
• Trailing arm bushings
• Ball joint and CV joint dust boots
• Air suspension components
• Strut mounting bushings
• Suspension travel limiters

In addition to suspension components, polyurethane parts are also used in other units and assemblies of the vehicle, replacing standard rubber consumables. These include: engine mounts, crankshaft damper pulley, subframe silent blocks, rod bushings, fastening elements of assemblies, etc.

The scope of application is not limited to passenger cars only. Polyurethane silent blocks and bushings can also be purchased for trucks, trailers, and special machinery. Considering the large mass of such vehicles, we use polyurethane material, which increases the reliability of components compared to conventional rubber.

Advantages of polyurethane parts in vehicle suspension

The main advantages of polyurethane parts from PoliPro are:

• Durability. Due to the high strength and elasticity of the material, the service life of the part increases by 3–5 times compared to conventional rubber bushings and silent blocks.
• Wear resistance. Suspension components are constantly exposed to aggressive environments (dirt, sand, chemicals, etc.), which act as abrasives and cause wear. Polyurethane bushings have high resistance to wear.
• Versatility. PoliPro offers products for various car models, which can be selected in the catalog on the website. If necessary, it is possible to place a custom order taking into account mounting wear.
• Improved vehicle handling characteristics. Polyurethane stabilizer bushings and silent blocks do not lose their properties during operation, ensuring good load resistance and reducing vibration when driving on poor roads due to their elasticity. These factors positively affect vehicle handling.

PoliPro uses high-tech 3-component polyurethane with different elasticity levels (from 45 to 90 Shore hardness). Our silent blocks have high tear resistance and recover their shape faster after deformation. The technology allows manufacturing parts “for worn seats”, which is typical for stabilizers and transverse rods. Thanks to this, you can buy polyurethane silent blocks that exceed original rubber parts in quality and service life.
