Daqing Shenrun Chemical Science&Technology Co.,Ltd, founded in 1990, is a professional manufacturer of waterproof EPDM (Ethylene-Propylene-Diene-Monomer) rubber rolls and Butyl rubber sub-materials. The factory has four production lines for EPDM rubber rolls with an annual output of 9 million square meters, and the production lines are equipped with pin cold feed rubber extruder and large-scale vulcanizing machine which is able to support continuous vulcanization. In 2004, we had Daqing XingPeng Co.,Ltd founded to make the whole group specialized in providing designing&developing, manufacturing and installing services. After that, we had another branch Zhejiang Shenrun Waterproof Technology Co.,Ltd for worldwide purpose and set up two production lines for EPDM rubber products on March 2017. Meanwhile, We keep improving the environment of our production area to comply with the Green Standards, and say no to any pollution.SEHNRUN sticks to scientific and technological innovation and believes that it is the way to success. We so far have had many series of products with different use through the non-stop development of waterproof EPDM rubber materials. Such as EPDM border adhibiting series applying to the artificial lake and the mechanical engineering, EPDM textile series applying to wet adhibiting for the underground and roof of civil architectures, EPDM waterproof sand-covered roll series applying to pre-installed and inverted adhered projects for large tunnels, EPDM reactive and self-adhesive butyl rubber roll series for single-layered roof and so on. In order to strengthen the effectivity of the entire waterproof project, SHENRUN has prepared dozens of sub-materials like flashing for nodes use in those roll series, self-adhesive butyl flashing with aluminum net inner for tile roof, waterproof and self-adhesive steel butyl rubber strip for tunnel projects, other kinds of self-adhesive butyl rubber tapes and so on.
