Product Description

This series of rubber pads is custom-developed for different engineering scenarios, offering two core material options: Natural Rubber (NR) and Chloroprene Rubber (CR). The products feature high tensile strength of ＞15MPa and excellent dynamic performance (dynamic-static stiffness ratio ＜1.5). After 3 million fatigue tests, the stiffness change is ＜15% and the thickness change is ＜10%, providing long-term stable vibration damping support for high-frequency impact scenarios such as rail transit and heavy-duty equipment.

PRODUCT FUNCTION

Dynamic performance optimization:  

The dynamic-static stiffness ratio is strictly controlled below 1.5, ensuring efficient absorption of vibration energy under dynamic loads.  

After 3 million fatigue cycles, the stiffness stability remains ＞85%, preventing performance degradation caused by long-term use.  

Material scenario adaptation:  

Natural Rubber (NR) series: Featuring high elasticity and low heat build-up, suitable for vibration damping in normal temperature environments.  

Chloroprene Rubber (CR) series: Oil-resistant and weather-resistant,适配 humid-heat/chemical corrosion working conditions.  

Structural durability guarantee:  

With tensile strength ＞15MPa and thickness change ＜10% after fatigue, it maintains structural integrity.  

Customized design support:  

Provide material and structural optimization solutions based on line load, environmental medium, and installation space.
