Which design institutes have experience in designing projects using EPDM rubber? Which companies are currently designing EPDM?
Are you going to go ahead with the ethylene-propylene rubber project? Do you use solution-based production techniques?
In China, only Jihua produces EPDM at present. However, the technology is from Mitsui, an old technology from the 1970s.

Now, Shandong Tianhong Chemical wants to produce EPDM rubber; I wonder which design institute is responsible for the design?
Sinopec Mitsui Petrochemical Co., Ltd. in Shanghai is also producing EPDM rubber (75,000 tons)
Jihua’s No. 9 Institute was involved. China still lacks independent, complete sets of technologies; the catalysts are no problem – that challenge has been overcome – but the main issue lies in the process engineering.
The pilot-scale data package I completed has been established at Yanhua, and the pilot plant has been put into operation. It’s basically proprietary technology; among the rubber types I’ve worked with, EPDM presents the greatest challenges in terms of engineering technology.
I wonder whether for ethylene-propylene rubber, more attention is paid to Mooney viscosity or conversion rate?
In addition to the projects mentioned by Shanghai You, Yanchang Group has also produced 50,000 tons of EPDM rubber, as have companies such as Shandong Yuhuang and Lanxess； It will soon be in excess! ! ! !
There is also CNOOC’s 50,000 tons per year facility. But apart from Sinopec, Mitsui, and Lanxess, the technologies of other companies can only be imported from Italy
