Who would like to know the difference between three yuan ethylene propylene rubber and three Yuan rubber coil? Can these two materials be bonded with the same kind of glue?
These two materials can use the same type of adhesive, but it is better to use the special adhesive provided by the manufacturer. Each adhesive is prepared according to the corresponding material, and the bonding effect will be different
Three EPDM waterproofing membrane is with ethylene, propylene and dicyclopentadiene three monomers synthesized three EPDM as the main body, adding proper amount of butyl rubber, vulcanizing agent, accelerant, softening agent, reinforcing agent and filler, batching, mixing, filtering, extrusion, drawing tablets (or calender) made process forming and vulcanization processing. Features: good aging resistance and long service life. Because there is no double bond of three membered ethylene propylene rubber structure in the main chain, so when subjected to ozone, ultraviolet radiation, heat, fracture occurs on the main chain, so it has excellent aging resistance and tensile strength. High, high elongation, deformation or cracking of the base of telescopic adaptability. Low temperature performance is good, can in the cold (-40 C) or long-term use of hot climates.
Three yuan Ding is not a chemical name, three yuan Ding waterproof coiled material is made, the old butyl rubber as the main material, adding butyl acrylate as modifier, and butanol as promoter, the processing of the material, its essence is the reclaimed rubber waterproof material, poor performance, China's production in 96 years, now almost no the production of three yuan. D: + + butanol butyl butyl rubber, this name is not scientific, and to three yuan to mix, I see should be called: the reclaimed butyl rubber waterproof material, at a glance.
Three yuan ethylene propylene and three yuan Ding is not the same thing, material performance is very different
