Shanghai Songjiang Vibration Absorber Group Co., Ltd. introduces to you: “Which rubber expansion joint is suitable for use with ethylene glycol as the medium?” Relevant information. We produce various rubber expansion joint products. Here is our company’s introduction to the question: Which rubber expansion joint is suitable for use with ethylene glycol as the medium?
Question: Using medium is ethylene glycol, which rubber expansion joint is suitable? Answer: If your use medium is ethylene glycol, then we recommend using EPDM rubber expansion joint products. EPDM rubber can be used on ethylene glycol pipelines.
Here is the answer found on the Internet: It should be possible. The characteristics of ethylene glycol are greater than those of methanol, certainly for polar solvents. And EPDM has good resistance to polar solvents. Ethylene propylene diene monomer rubber (EPDM) is a terpolymer of ethylene, propylene, and a non-conjugated diene, which began commercial production in 1963. The global consumption is 800,000 tons per year. EPDM’s main polarity is its superior resistance to oxidation, ozone, and corrosion. Since EPDM belongs to the family of polyolefins, it has good vulcanization properties. Among all rubbers, EPDM has the lowest specific gravity. It can absorb a large amount of filler and oil without significantly affecting its properties. Therefore, it can be made into inexpensive rubber compounds.
