When it comes to engine mounts, there are two common options: rubber and polyurethane. While rubber has been the traditional elastomer of choice for many years across different applications, polyurethane holds numerous advantages over rubber as a material choice for motor mounts and more.
Polyurethane vs Rubber Motor Mounts
Motor mounts, also called engine mounts, are essential components of a vehicle’s engine system. They are responsible for securing the engine to the chassis and absorbing the vibrations and movements of the engine during operation.
Motor mounts are typically made of rubber or polyurethane, with rubber being the more common choice. However, polyurethane motor mounts are becoming increasingly popular due to their superior performance and durability.
Improved Performance
Polyurethane motor mounts offer better performance compared to rubber mounts. Rubber engine mounts tend to flex and deform under heavy loads, which can cause the engine to move and affect its performance. This can result in a decrease in power and acceleration, as well as increased fuel consumption.
Polyurethane motor mounts, on the other hand, rebound and resist compression from heavy loads, providing better support and stability for the engine. This results in improved performance, better handling, and increased power and acceleration.
Reduced Vibration and Noise
One of the most significant advantages of polyurethane motor mounts is their ability to reduce engine vibrations and noise. Rubber engine mounts can absorb vibrations and movements to an extent, but they can also transfer them to the chassis and cabin, resulting in a noisy and uncomfortable ride.
Polyurethane motor mounts, on the other hand, are better at absorbing vibrations and preventing them from transferring to the chassis and cabin. This results in a smoother and quieter ride, making it more comfortable for both the driver and passengers.
Durability and Longevity
One of the main advantages of polyurethane motor mounts is their durability and longevity. Rubber motor mounts wear out and deteriorate over time, especially in high-performance vehicles. This can lead to engine vibrations and movements not being properly absorbed, resulting in a rough and uncomfortable ride.
On the other hand, polyurethane motor mounts are much more durable and can withstand high levels of stress and pressure. Compared to rubber, polyurethane motor mounts can last up to 4 times as long before needing to be replaced. They are also resistant to oil, chemicals, and extreme temperatures, making them ideal for use in high-performance vehicles.
Cost-Effective
While polyurethane motor mounts may have a higher upfront cost compared to rubber ones, they are more cost-effective in the long run. Rubber mounts more quickly wear out and need to be replaced more frequently, resulting in additional costs for the vehicle owner.
Polyurethane motor mounts, on the other hand, have a longer lifespan and do not need to be replaced as often. This makes them a more cost-effective option overall, saving vehicle owners money on maintenance and replacements.

Benefits of Using Polyurethane vs Rubber Motor Mounts
Improved Engine Stability
Polyurethane motor mounts provide better support and stability for the engine compared to rubber engine mounts. This is especially important in high-performance vehicles where the engine is under more stress and pressure. With improved stability, the engine can perform at its best, resulting in better overall vehicle performance.
Better Handling and Control
Polyurethane motor mounts also contribute to better handling and control of the vehicle. With improved stability and reduced engine movements, the driver can have better control over the vehicle, resulting in a safer and more enjoyable driving experience.
Increased Power and Acceleration
As mentioned earlier, polyurethane motor mounts can improve the performance of the engine. With better support and stability, the engine can operate at its full potential, resulting in increased power and acceleration. This is especially beneficial for high-performance vehicles where power and speed are crucial.
Longer Lifespan
Polyurethane motor mounts have a longer lifespan compared to rubber mounts. This is due to their durability and resistance to wear and tear. With proper maintenance, polyurethane motor mounts can last for the lifetime of the vehicle, saving vehicle owners money on replacements.
Easy to Install
Polyurethane motor mounts are relatively easy to install, making them a popular choice for aftermarket vehicle upgrades and DIY enthusiasts. They can be easily replaced without the need for special tools or equipment, saving vehicle owners time and money on installation costs.

How to Choose the Right Manufacturer for Polyurethane Motor Mounts
When choosing a manufacturer for polyurethane motor mounts, there are a few factors to consider to ensure you get the right ones for your project.
Engine Type
The type of engine will determine the type of polyurethane motor mounts you need. Different vehicles have different engine sizes and weights, which require different types of motor mounts. Make sure to specify the parameters of the motor itself and the size of the engine bay to ensure an effective motor mount design.
Performance Needs
In a high-performance vehicle, motor mounts must be able to withstand high levels of stress, vibrations, heat, and pressure. Look for a manufacturer that can produce polyurethane motor mounts that are specifically designed for high-performance vehicles, to ensure they can handle the demands of a high displacement engine.
Quality and Brand Reputation
When it comes to motor mounts, quality is crucial, especially in performance vehicles. Look for reputable polyurethane manufacturers that have a proven track record of producing high-quality motor mounts. This will ensure that you get a reliable and durable product that will last for a long time.
Polyurethane motor mounts offer numerous advantages over rubber mounts, making them a popular choice for vehicle owners. With improved durability, performance, and reduced vibrations and noise, polyurethane motor mounts can provide a smoother and more enjoyable driving experience. They are also cost-effective in the long run, making them a smart investment for any vehicle owner. When choosing a manufacturer for polyurethane motor mounts, make sure to consider your vehicle type, performance needs, and the quality and reputation of the brand to ensure you get the best polyurethane motor mounts for your application.
