Poly(methyl methacrylate), more often called PMMA, is a commonly used low cost thermoplastic polymer with boundless applications to everyday life. PMMA is the most commercially important acrylic polymer and is sold under several trade names including Plexiglas® and Acrylite®. High transparency makes PMMA an ideal replacement for glass where impact or weight is a serious concern. PMMA is compatible with human tissue making it an important material for transplants and prosthetics, especially in the field of ophthalmology because of its transparent properties. PMMA is formed through block, emulsion or suspension polymerization of methacrylic acid. PMMA was thought to be an atactic polymer through the first half of the 20th century. This means that the substituents of the molecular chain alternate randomly along the chain, which is illustrated in Figure 1A below. Since the development of modern equipment and techniques, it has been determined that the molecular chains are mostly syndiotactic (Figure 1B), meaning the molecular chain’s substituents alternate uniformly. Final processing of PMMA is accomplished through injection molding or extrusion at melt temperatures ranging from 200-230 ºC.
BRP offers PMMA/acrylic and acrylic glass sheets, film, tubes and rods in a variety of colors. PMMA or Polymethyl methacrylate, more commonly known as acrylic or acrylic glass, is one of the most economical and easily fabricated plastics for aesthetic applications - often considered an economical alternative to polycarbonate (when extreme strength is not needed). Many people also refer to acrylic as Plexiglass, Acrylite, Lucite , Perspex and other trade names. Acrylic is available in a variety of translucent and opaque colors. The light weight (less than 50% as heavy as glass) and high impact resistance (6-17 times the impact resistance of glass) make it the material of choice for displays, glazing and other popular glass applications.
Acrylic is also noted for its ease of fabrication. Acrylic can be machined, routed, drilled and cut as easily as wood. When heated, acrylic can be bent into almost any shape. Upon cooling the material retains the shape with surprising stability. We have Acrylic available in sheet, rod, film, and tube for all applications. Acrylic is being used in decorative applications as well for products like curtain rods, pergolas and more.
oExtruded: By far the most economical of the acrylics. The extruded material maintains most of the properties of the cell cast. Extruded acrylic is available as a colorless sheet as well as in standard colors.
oCell Cast: Cast acrylic offers easier cutting and routing as well as a wider array of colors.
oSpecialty Grades: UV Filtering,UV Transmitting, Antiglare, Fluorescent, Abrasion Resistant,Texture,Imbedded, Matte Finish & Mirrored
