Silent blocks are suspension joints consisting of metal sleeves bonded by a resilient polymer element. The combination of metal and elastic material allows the silent block to operate under torsional, compressive, and tensile loads while absorbing vibrations and impact forces. This helps ensure a smoother ride, improved driving comfort, and protection of suspension components against premature wear. Learn how PolyPro polyurethane silent blocks can extend the service life of critical suspension components and discover the benefits of working with one of Ukraine’s largest manufacturers of polyurethane automotive parts.
PolyPro Polyurethane Silent Blocks and Bushings: Benefits and Key Features.
Vehicle manufacturers and suppliers of original replacement parts primarily use rubber silent blocks and joints fitted with rubber bushings. However, these components are often not sold separately, so replacing them may require purchasing the complete control arm or another assembled suspension unit. This significantly increases repair costs. In addition, original parts for certain vehicle makes and models may be difficult to find or unavailable on the Ukrainian market.
PolyPro, a Ukrainian manufacturer of polyurethane silent blocks, bushings, and other suspension components, helps solve this problem. The company’s product range includes tens of thousands of automotive parts that match genuine components in performance and, in many cases, surpass rubber alternatives in strength and durability.
The PolyPro catalogue includes polyurethane bushings for shock absorbers, subframes, differentials, steering racks, control arms, and other suspension assemblies. It also features anti-roll bar bushings and links, polyurethane components for various pivot joints, dust boots, engine mounts, and many other parts for a wide range of vehicle makes and models. In addition, the company provides control arm and suspension assembly reconditioning services.
PolyPro operates its own warehouse with a large stock of ready-to-ship products and also manufactures parts to order according to individual specifications. For nearly 15 years, PolyPro’s signature bright orange components have been associated with high quality and reliability among customers. The products are covered by a 1-year warranty with no mileage limit.
To address non-standard technical requirements, the company follows a well-established customer support process. PolyPro’s technical specialists advise both business partners and end customers, assist with parts selection, and coordinate custom manufacturing according to individual specifications. Wholesale customers are offered.
Polyurethane or Rubber Bushings and Silent Blocks: Which Should You Choose?
Most of our customers have already experienced the benefits of polyurethane suspension components. However, some potential buyers still question whether standard rubber bushings and silent blocks should be replaced with polyurethane alternatives. These concerns are most often based on common misconceptions about the properties of polyurethane.
The Three Most Common Myths:
- polyurethane bushings are harder than rubber ones and accelerate wear of the control arm’s metal surfaces.
- polyurethane hardens at low temperatures.
- polyurethane components have a shorter service life than rubber ones.
Such claims may result from the use of low-quality raw materials or violations of the manufacturing process. PolyPro polyurethane silent blocks and bushings, produced in compliance with all technological requirements, disprove these myths.
Both rubber and polyurethane are elastomers. Depending on their formulation, these materials can range from soft and flexible to significantly harder. Most PolyPro components have a hardness of 65 Shore A, which is comparable to standard rubber suspension parts. For components operating under increased loads, polyurethane with a hardness of 85 or 90 Shore A may be used. The required hardness is selected according to the component design, vehicle operating conditions, and the loads applied to the suspension assembly.
Metal wear is caused by dirt and sand entering the contact areas between the control arm components. Delayed replacement of worn rubber joints can also lead to this problem. Therefore, when installing polyurethane silent blocks, it may sometimes be necessary to select a non-standard size based on the actual diameter of the mounting bore.
The properties of the three-component cast polyurethane used in PolyPro products remain stable within a temperature range of –18 °C to +30 °C. Therefore, under normal winter conditions, no significant changes in suspension performance should be noticeable. At temperatures below –20 °C, the suspension may become slightly stiffer; however, rubber also loses a noticeable amount of elasticity under such extreme conditions.
Thanks to its physical and mechanical properties, polyurethane offers greater abrasion resistance, higher tensile and torsional strength, and better resistance to aggressive chemicals than rubber. We are confident in the quality of our products and therefore provide a warranty on all components manufactured by PolyPro. How many manufacturers of rubber replacement parts supply their products with warranty certificates?
It is therefore no surprise that polyurethane bushings and silent blocks have become increasingly popular worldwide over the past 25 years, particularly in reinforced and heavy-duty suspension systems.
We offer favourable partnership terms and unique opportunities to grow your business with a reliable Ukrainian manufacturer of polyurethane silent blocks and other automotive parts for a wide range of vehicle makes and models.
