Polyurethane is a synthetic rubber. Due to its technical characteristics, it is used in various industries, including automotive. Material properties: - can be used in aggressive environments; - working temperature range from -60 to +100 °C; - does not absorb moisture; - quickly returns to its shape after deformation; - has high dielectric properties. Mainly, the raw material is used in modern industry as a substitute for rubber and some types of metal. ### Rubber vs Polyurethane: What to Choose for Your Car? To dampen strong vibrations during vehicle movement and soften impacts in the area where the suspension is attached to the car body, silent blocks are used. This part consists of two connected bushings. They are made from elastic materials - rubber or polyurethane. However, recently, the second option has gained more popularity due to the following reasons: 1. Long service life. 2. High elasticity and ability to return to original shape after deformation. 3. Strength and wear resistance. 4. Resistance to temperature fluctuations. Rubber bushings are not durable. According to mechanics, play in the shock absorber joints can be detected after just two years. This causes the suspension to start squeaking. Additionally, rubber quickly loses its shape. Moreover, the material is more prone to deformation, especially after impacts. Cracks appear on the surface, necessitating part replacement. After installing polymer bushings, the car is easier to handle, and it takes turns better without strong skids, even on wet roads. Rubber auto parts are more suitable for those who enjoy smooth driving on perfectly flat roads. However, as mentioned above, their service life is short, so you will have to replace them more often. By installing polymer parts, you will significantly reduce maintenance costs for your vehicle. The only drawback of polymer parts is their higher cost compared to rubber products. However, the expenses quickly pay off since their service life is twice as long as that of their analogs. ### How to Choose Polymer Shock Absorbing Parts? One of the main characteristics of stabilizer bushings is their elasticity (hardness and stiffness). This parameter ensures driver comfort during vehicle movement and the longevity of the stabilizer and other suspension parts. Professional mechanics recommend installing polymer bushings with hardness ratings of 50 Shore A - 70 Shore D. Harder parts can cause abrasive wear on the shaft in the area of the silent blocks. This will lead to increased friction, squeaks, and so on. The main feature is that you have to trust the data provided by the manufacturer on the packaging of the parts. Hardness can only be measured with a special device, which is not commonly found in auto shops or with sellers at markets. However, you can check how elastic the bushings are on your own: if the product feels like rubber to the touch, then this item can be purchased. A harder polymer similar to plastic does not bend much. In addition to elasticity ratings, you should also consider the expected service life of the products. Typically, this parameter is also indicated by the manufacturer on the packaging. On average, it ranges from a few months to two years. Of course, it is better to buy parts with a longer warranty period to avoid frequent replacements. There are parts available in various colors, but this parameter does not affect the functionality or service life of the part. The polymer itself is transparent with a slight light brown tint. Some manufacturers add dye to the composition during production, but this does not affect the technical properties of the parts. However, the cost of colored products may be slightly higher due to their more aesthetic appearance. ### Which Company Makes the Best Polyurethane Bushings? The Ukrainian factory "Timol" offers wear-resistant polyurethane products. This manufacturer provides the best options for polymer bushings for vehicles. The enterprise operates on modern, certified equipment, producing parts with high technical characteristics. All finished products meet international quality and safety standards. Components produced at the "Timol" factory demonstrate high wear resistance and can withstand significant mechanical and physical loads. Additionally, automotive bushings are resistant to temperature fluctuations and the effects of technical lubricants. Due to their elasticity, the parts effectively dampen vibrations and shocks during vehicle movement. Unlike rubber counterparts, they will serve you much longer, allowing you to save on vehicle maintenance costs. You can purchase polyurethane auto parts by contacting the company's managers. This can be done through the contact numbers listed on the website or through other communication channels (e-mail, fax). They will provide detailed consultations regarding the technical properties of the products, dimensions, and other parameters, as well as quote the exact amount for your future order.
