A silent block is a part that connects the suspension nodes to each other. The main function of the silent block is to absorb vibrations that occur when the car is moving. The standard silent block is a metal base and an elastic insert made of rubber or polyurethane.
It is well known that how many people, so many opinions. Therefore, many car owners are wondering which silent blocks are better polyurethane or rubber. Below we will try to answer this question.
The main disadvantage is known to all car owners - the rubber resource is not too large, it tends to dry out and crack. No less detrimental than time, rubber silent blocks are affected by prolonged frosts and sudden changes in temperature. The reagents used to treat roads in cities also reduce the life of rubber products.
If the suspension is not repaired for a long time, then the rubber parts will wear out, becoming too soft. This negatively affects the handling of the car.
Polyurethane gives the suspension extra rigidity, which allows the driver to feel the vehicle better while riding.
The main advantages of polyurethane silent blocks:
The only drawback, perhaps, is the cost - rubber products are somewhat cheaper due to the lower cost of production.
If you do not like to repair the suspension of your iron horse every year, then polyurethane products will be the perfect solution for you.
As the say: "I'm not rich enough to buy cheap things." Ordinary rubber silent retains its performance characteristics 2, and sometimes 3 times less than polyurethane. Therefore, if you opt for polyurethane products, you will repair the chassis of the car much less frequently.
Let's add to the above the fact that rubber, when driving off-road, completely loses to polyurethane silents in terms of vibration damping.
Some motorists constantly sting, they say, polyurethane always creaks, but rubber does not. In fact, it happens that any silent blocks creak. It all depends on the manufacturer and its technologies.
It is well known that demand creates supply. Therefore, in the modern market for automotive parts, you can find many manufacturers of polyurethane products. All have different production technologies, different composition of raw materials and different directions. Someone specializes in the production of cheap polyurethane silent blocks, which are a little better than rubber, and someone supplies high-quality products to the market.
