The data set represents the process for producing polymethyl methacrylate (PMMA) monomer, MMA, through an electric energy heating process in a cracking kettle. This high purity chemical is utilized for manufacturing polymethyl methacrylate (PMMA), commonly known as acrylic or acrylic glass. It is widely used in applications such as the production of transparent structural materials, like windows, shielding barriers, and lightweight lenses. When using this data set for Life Cycle Assessment (LCA) of PMMA products, attention should be paid to the system boundaries, allocation, and energy sources. Ensure that the electricity consumption is correctly accounted for in the relevant geographical energy mix. If the PMMA is being recycled, users should take into account the recycling process according to the end-of-life scenario of the product, and possibly amend the data set with recycling rates.
