High-Temperature Viscoelasticity of EPDM Rubber Gaskets: Mechanisms Behind Long-Term Softening and Creep
In high-temperature industrial scenarios—such as industrial sealing systems, heating pipelines, and automotive components—EPDM (Ethylene Propylene Diene Monomer) gaskets are widely favored for their exceptional weather resistance and corrosion resistance. However, a common challenge arises: prolonged exposure to temperatures above 80℃ often leads to softening, deformation, and creep, compromising sealing integrity and even triggering leakage risks. The root cause lies in the significant shifts in EPDM’s intrinsic viscoelastic properties under high-temperature conditions. This article delves into the high-temperature viscoelastic behavior of EPDM rubber gaskets, exploring its underlying mechanisms, influencing factors, and... 阅读详细内容…
Applications of EPDM Gaskets in the Packaging of Electronic Manufacturing Components and Equipment Assembly
In the field of precision electronic manufacturing, as the industry evolves toward miniaturization, high performance, and high reliability, the hermeticity of electronic component packaging and the stability of equipment assembly directly determine product lifespan and user experience. According to survey data from the IPC Association Connecting Electronics Industries, more than 18% of early failures in electronic products are associated with the failure of internal protective materials. EPDM, with its weather resistance, hermetic sealing properties, cushioning and shock absorption capabilities, and electrical insulation performance, has become an essential material in electronic... 阅读详细内容…
EPDM Gasket Oil Resistance Feasibility Analysis and Solutions
With its excellent weather resistance, aging resistance and corrosion resistance, EPDM gaskets have become the preferred material for scenarios such as sealing, pipeline connection and equipment protection in the industrial field. However, insufficient oil resistance is an inherent shortcoming of EPDM gaskets, which limits their application in oil-medium working conditions including automobile manufacturing, chemical equipment and mechanical hydraulics. In fact, the oil resistance of EPDM gaskets is not an absolute weakness. Through scientific working condition matching, formula modification and structural optimization, stable sealing of EPDM in oil-medium environments can be... 阅读详细内容…
