EPiC database - Polymethyl methacrylate (PMMA)

This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.Polymethyl methacrylate (PMMA) is a transparent thermoplastic that is light-weight has a good tensile strength, flexural strength and UV tolerance. It is commonly known as plexiglass, acrylic or acrylic glass.PMMA is made by polymerising monomers of methyl-methacrylate. It is moulded or extruded into its final shape, which is often flat sheets. Common additives include acrylate monomers for heat processing, butyl acrylate for impact strength, dyes for colouring and ultraviolet resistance and fillers to reduce cost.PMMA is most often used in construction as a substitute to glass.
