In the application of electronic products, PMI foam has excellent insulation properties. It can isolate electronic components, preventing short circuits and electric shock. It is lightweight yet strong, able to withstand certain external impacts and pressure, protecting the stable operation of internal electronic components. It is heat - resistant and easy to process, allowing for customized processing according to the shape and size requirements of electronic products and mass production.
Traditional diaphragm materials are mostly paper - based, which are easily affected by the environment. Common plastic diaphragms such as PP have poor rigidity and are prone to distortion. PMI diaphragm has lightweight and high rigidity, and excellent damping properties. It can effectively absorb and consume vibration energy, thus reducing the generation of mechanical vibration and noise.
