The empirical and molecular formula for water looks like this: H2O It can also be used to provide cushioning or elasticity. EPDM has good low-temperature properties, with elastic properties to temperatures as low as 40C depending on the grade and the formulation. This synthetic rubber membrane has also been used for flat roofs because of its durability and low maintenance costs. EPDM is a non-toxic, FDA-approved synthetic material that has gained widespread industry popularity for its excellent resistance and chemical compatibility properties. EPDM is an extremely durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) widely used in low-slope buildings in the United States and worldwide. Most peroxides do not bloom and have better color control and stability. EPDM is also based on the same constituent monomers, however as no unsaturation is present in the backbone, it is added as a third monomer pendent to the main chain. Empirical formulae are usually obtained based on the analysis of experimental data. EPDM compounds are frequently used with foods, water, steam and phosphate ester fluids (Skydrol) applications and offer the excellent resistance to brake fluids (glycol base), weather, and ozone. epdm-rubber-formula-compounding-guide 2/6 Downloaded from edocs.utsa.edu on November 7, 2022 by guest Rubber as a Construction Material for Corrosion Protection V.
