Polymethyl Methacrylate (PMMA), commonly known as acrylic or plexiglass, offers optical clarity and excellent mechanical properties, such as high tensile strength and impact resistance. Additionally it provides chemical- and UV-resistance.
Polymethyl Methacrylate (PMMA), commonly known as acrylic or plexiglass, is a versatile material with various desirable properties. PMMA is particularly valued for its optical clarity, making it an excellent choice for applications where transparency, aesthetics, and light transmission are important, such as display cases, signage, architectural models, and more.
Beyond its optical properties, PMMA exhibits excellent mechanical characteristics. It possesses high tensile strength and impact resistance, making it stronger and more durable compared to materials like PLA or ABS. This strength allows PMMA to withstand demanding conditions and endure impacts without compromising its integrity.
PMMA also offers notable chemical resistance, demonstrating good resistance to acids, alkalis, and other substances. Additionally, it excels in its resistance to ultraviolet (UV) light degradation. PMMA maintains its clarity and mechanical properties when exposed to sunlight or other UV sources, making it a preferred choice for outdoor applications.
The technical properties of PMMA are as follows:
|Tensile Strength||55 - 80 MPa|
|Tensile Modulus||2000 - 3000 MPa|
|Tensile Elongation||2 - 5%|
|Flexural Strength||90 - 130 MPa|
|Flexural Modulus||2500 - 3500 MPa|
|HDT (0.45 MPa)||70 - 89°C|
|HDT (1.8 MPa)||65 - 85°C|
Please note that the values provided for the technical properties are approximate ranges and can vary depending on specific formulations, manufacturing processes, and testing conditions. It's always recommended to refer to the manufacturer's documentation or data sheets for precise and up-to-date technical specifications for the specific brand and formulation of PMMA.
