Poly (methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic, used as an engineering plastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others (see below).

2021年12月14日 · PMMA or poly (methyl 2‐methylpropenoate) is produced from the monomer methyl methacrylate. It is a clear, colorless polymer available in pellet, small granules, and sheet forms. They are then formed with all thermoplastic methods including injection molding, compression molding, and extrusion.

PMMA, or acrylic, is a versatile plastic with unique properties. It offers excellent transparency, durability, and weather resistance. PMMA can be enhanced with additives and processed using various methods to suit specific applications.

Poly (methyl methacrylate) (PMMA) (Fig. 33.1F) is a non-degradable polyacrylate and is the most commonly applied non-metallic implant material in orthopedics. After being used as an essential ingredient in making dentures, PMMA was introduced to orthopedic surgery in the mid 1950s (Saha and Pal, 1984).

2025年1月3日 · Polymethyl methacrylate (PMMA), a synthetic resin produced from the polymerization of methyl methacrylate. A transparent and rigid plastic, PMMA is often used as a substitute for glass in products such as shatterproof windows, skylights, illuminated signs, and aircraft canopies.

PMMA, or polymethyl methacrylate, is a synthetic polymer known for its exceptional clarity and light transmittance, which is on par with that of glass. However, unlike glass, PMMA is significantly lighter and more impact-resistant, making it a versatile alternative in various applications.

2024年8月16日 · PMMA, or polymethyl methacrylate, is a polymer synthesized from methyl methacrylate monomers9. PMMA is a highly favored thermoplastic material for manufacturing and medical applications due to its exceptional impact resistance, lightweight nature …

Polymethyl methacrylate (PMMA) is a synthetic polymer made from the polymerization of methyl methacrylate monomers. It is a transparent thermoplastic that has excellent optical clarity, making it a popular material for applications such as acrylic glass, lenses, and other transparent or translucent products.

Poly(methyl methacrylate) (PMMA) is an amorphous, transparent, and hydrophobic thermoplastic polymer that is very hard and stiff but brittle and notch-sensitive (Figure 11). PMMA, commonly known as “safety glass,” is an “acrylate” with brand names such as Plexiglas, Diakon, and Lucite.

Polymethyl-methacrylate (PMMA) is an acrylic bone cement used in hip and knee arthroplasty and spinal procedures such as vertebroplasty and kyphoplasty. Although PMMA provides excellent fixation, it has some disadvantages. When PMMA is applied, an exotherm reaction can cause necrosis of bone tissue.
