General Description : Often just called "acrylic" - though this really describes a large family of chemically related polymers - PMMA is an amorphous, transparent and colourless thermoplastic that is hard and stiff but brittle and notch-sensitive. The reaction between methacrylic acid and methanol results in the ester methyl methacrylate. PMMA is commonly used for constructing residential and commercial, PMMA is used for viewing ports and even complete pressure hulls of submersibles, such as the. [24] Annealing the PMMA sheet/parts is therefore an obligatory post-processing step when intending to chemically bond lasercut parts together. [28], PMMA has a maximum water absorption ratio of 0.3–0.4% by weight. We offer a variety of poly (methyl methacrylate) (PMMA) materials for your bioelectronics research. Polymethyl Methacrylate, Powder, also known as methyl methacrylate resin, is used as a lightweight alternative to soda-lime glass.

The Tg values of commercial grades of PMMA range from 85 to 165 °C (185 to 329 °F); the range is so wide because of the vast number of commercial compositions which are copolymers with co-monomers other than methyl methacrylate. The glass transition temperature (Tg) of atactic PMMA is 105 °C (221 °F). PMMA can be joined using cyanoacrylate cement (commonly known as superglue), with heat (welding), or by using chlorinated solvents such as dichloromethane or trichloromethane[23] (chloroform) to dissolve the plastic at the joint, which then fuses and sets, forming an almost invisible weld. [6] Additionally, PMMA does not contain the potentially harmful bisphenol-A subunits found in polycarbonate and is a far better choice for laser cutting. Soluble in tetrahydrofuran, toluene, cyclohexanone, ethyl acetate and chloroform. Lucite beads and ornaments are still sold by jewelry suppliers. Hence, it is used in optical fibers. PMMA ist z.
