The official website of Shanghai Songjiang Vibration Absorber Group Co., Ltd. presents the quantitative inspection report of EPDM rubber expansion joint components, indicating a content level of 46%~47%. In order to ensure our customers have a reliable product, Songjiang Group conducted quantitative inspections of the EPDM content inside the rubber expansion joints. Below are the results of the inspection report.
Explanation: When testing the EPDM content of Songjiang Group’s brand of EPDM rubber expansion joint products, it is important to note that the EPDM rubber inside the joint’s inner diameter is cut off for quantitative content inspection. This is because the inner layer of the EPDM rubber expansion joint is made of EPDM rubber, while the skeletal layer inside is made of polyester cord fabric, which does not contain EPDM rubber components. Therefore, some customers may mistakenly attempt to test the EPDM content by inspecting the entire rubber expansion joint, which would not accurately determine the EPDM content.
