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.

本材料属于免费的环境性能在建筑领域（Environmental Performance in Construction，简称EPiC）数据库的一部分。该EPiC数据库包含超过250种建筑材料的环境流系数，采用了一种全面的混合生命周期清单方法进行评估。聚甲基丙烯酸甲酯（Polymethyl methacrylate，简称PMMA）是一种轻质、具有良好拉伸强度、弯曲强度和耐紫外线性能的透明热塑性塑料。它通常被称为亚克力板、丙烯或丙烯玻璃。PMMA通过甲基丙烯酸甲酯单体的聚合制备而成。它被塑形或挤出成最终形状，通常是平板。常见的添加剂包括用于热处理的丙烯酸单体、用于提高冲击强度的丁基丙烯酸酯、用于着色和耐紫外线的染料以及用于降低成本的填料。PMMA在建筑领域最常被用作玻璃的替代品。
