Rubber Gaskets for Electronics

Rubber Gaskets for Electronics is a kind of ring-shaped parts made of ethylene propylene diene monomer (EPDM) rubber material and produced by mold forming, which are used for sealing and protection of electronic devices. Its main function is to fill the microscopic gaps at the seams, interfaces or cover plates of electronic devices' casings. By taking advantage of the elasticity and conductive/insulating properties of rubber, it achieves dust-proofing, water-proofing, shock-proofing and electromagnetic shielding. In China, for 15 years, Liangju's R&D team has been dedicated to developing advanced elastomer formulations with performance surpassing traditional materials to cope with harsh working environments.

Advantages and features

Our Rubber Gaskets for Electronics adopts a patented formula, making it have excellent oil resistance; Unlike ordinary rubber gaskets that degrade upon contact with oil stains, our unique compound demonstrates outstanding stability. After being immersed in ASTM #3 oil at 125℃ for more than 1000 hours, the volume expansion rate remains below 5%. It can still maintain over 90% of its original tensile strength after long-term oil immersion. Even after continuous compression in an oil-containing environment, it shows an extremely small compression set (≤15%).

This makes it applicable in automotive electronic products (ECUs, sensors, connectors) and industrial control systems. It is particularly valuable in the fields of oil and gas monitoring equipment and food processing machinery and electronic products
