Industry
When it comes to the transportation industry polyurethane can be used in many ways. We supply jounce bumpers, Shock absorbers, Transmission mounts, Anti-vibration pads, PU
Springs & Dampers and many more. The list is extensive and continuing to grow for this demanding market sector.
As with many other industries, polyurethane is replacing traditional rubbers, plastics and even steel. When compared with steel, this super material can absorb vibration which reduces
noise, is lighter weight, abrasion and wear resistant, and cheaper to manufacture as there is no requirement for expensive processes like welding or machining.

OUR PRODUCTS
POLYURETHANE JOUNCE BUMPERS
polyurethane jounce bumpers play a crucial role in the automobile industry by enhancing
vehicle suspension systems’ performance and durability. Due to their robust nature,
polyurethane jounce bumpers are capable of enduring the rigors of daily driving as well as
more demanding conditions, such as off-road or heavy-duty applications. By absorbing
and dispersing energy from impacts, polyurethane jounce bumpers help protect other
suspension components, such as springs and shock absorbers, from premature wear and
damage. Polyurethane jounce bumpers can be customized in terms of shape, size, and
hardness to suit specific vehicle applications and performance requirements.
Unlike metal springs that can be uncomfortable or breakdown, polyurethane foam jounce
bumpers act as dampers, absorbing energy and reducing bounce when the jounces engage
and return. Polyurethane foam is also ideal for coil spring assists where additional load
support and suspension amplitude damping are needed, such as when towing.
PU SHOCK ABSORBERS
Polyurethane, known for its durability and resilience, is used to construct the shock absorber body. This
material offers excellent resistance to abrasion, corrosion, and deformation, ensuring long-term
reliability and performance. Our shock absorbers effectively dampen oscillations and vibrations in the
suspension system, providing a smoother and more controlled ride. They help maintain tire contact
with the road surface, improving traction and stability. Polyurethane shock absorbers find applications
in various vehicles, including passenger cars, trucks, SUVs, and off-road vehicles. They are particularly
popular in performance-oriented and heavy-duty applications where durability and performance are
paramount.
Compared to traditional metal shock absorbers, polyurethane variants are often lighter in weight. This
reduction in mass can contribute to overall vehicle weight savings, enhancing fuel efficiency and
handling characteristics.
PU TRANSMISSION MOUNTS
polyurethane transmission mounts effectively dampen vibrations and noise generated by
the transmission assembly, resulting in a smoother and quieter driving experience. By
reducing the transmission’s transfer of vibrations to the vehicle chassis, they enhance
overall ride comfort. Our mounts provide firmer support for the transmission, minimizing
excessive movement and flex during acceleration, deceleration, and cornering. This helps
maintain drivetrain stability and prevents damage to other drivetrain components. These
mounts are resistant to degradation from environmental factors such as oil, grease, and
temperature fluctuations. This ensures that the mounts maintain their performance and
integrity over time, even under harsh operating conditions.
Our transmission mounts offer several advantages over traditional rubber mounts,
including improved durability, vibration dampening, performance enhancement, and
customization options. They are a popular choice for automotive enthusiasts and
performance-oriented drivers seeking to optimize drivetrain stability and overall vehicle
dynamics.
ANTI-VIBRATION PADS
By reducing the transmission of vibrations from the engine and other moving parts to the vehicle
chassis, our polyurethane anti-vibration pads contribute to a smoother and more comfortable ride for
passengers. They help dampen road noise and vibrations, creating a quieter and more enjoyable driving
experience. These pads are engineered to absorb and dissipate vibrations generated by machinery.
equipment, or structural elements. Typically, these pads are easy to install and can be placed directly
under machinery bases or mounting surfaces. They require minimal preparation and can be quickly
integrated into existing systems. Our pads are resistant to many chemicals, oils, and solvents, making it
suitable for use in various industrial environments where exposure to corrosive substances is common.
In addition to vibration dampening, polyurethane pads can help reduce noise levels generated by
machinery and equipment, creating a quieter and more comfortable work environment.
PU SPRINGS & DAMPERS
Traditionally, springs in suspension systems are made of steel. However, polyurethane
springs offer several advantages. PU Springs known for its durability, resistance to
abrasion, ability to withstand varying temperatures and provide a smoother ride compared
to steel springs because it can absorb more energy, reducing the transfer of vibrations
from the road to the vehicle. Additionally, polyurethane springs are lighter than steel ones,
contributing to improved fuel efficiency and handling. They can also be designed with
different stiffness levels to suit specific vehicle applications.
Polyurethane dampers use the same material as polyurethane springs but serve a different
purpose. They absorb kinetic energy generated by the movement of the suspension
system, converting it into heat, which is dissipated away. This action helps in stabilizing
the vehicle’s motion, preventing excessive bouncing, and enhancing overall ride quality.
