What type of polymer is PMMA?
PMMA is a highly transparent thermoplastic polymer, obtained by polymerization of the methylmethacrylate monomer. Due to its transparency, aesthetics and scratch resistance PMMA might be considered the light alternative to glass. It is also sometimes called acrylic glass.
What is PMMA powder?
Poly (methyl methacrylate) (PMMA) is an amorphous transparent thermoplastic polymer. PMMA is recognized as an optical polymer based on its refractive index (1.49). Hence, it is used in optical fibers. It finds uses in biological applications because of its lower water absorption capability and biocompatibility.
Is PMMA a polymer?
Polymethyl methacrylate (PMMA) belongs to a family of synthetic polymers. It is better known as acrylic and is sold under brand names such as Akrylon®, Altuglas®, Perspex®, Plazcryl®, Plexiglas®, Oroglas®, Solarkote™ Diakon® , Acrypet™, Crylon® and Crylux®. Like all plastics, acrylics are polymers.
How is PMMA produced?
PMMA is made through a process called polymerization. The methyl methacrylate is placed into a mold along with a catalyst that is added to speed up the process. Due to this process, PMMA can be shaped into many forms such as sheets, blocks, resins, and beads.
What is PMMA used for?
PMMA is often used as a lighter, shatter-resistant alternative to glass in everything from windows, aquariums and hockey rinks. Therefore, it’s hard to fathom that this easy-to-process, low-cost, versatile material is also used in dentures, bone implants and more.
Is PMMA a plastic?
PMMA or acrylic is a widely used transparent plastic material known for its applications in various markets from car windows, smartphone screens to aquariums. It is a tough plastic, easy to shape and a great alternative to the high cost and less resilient glass.
Is PMMA the same as acrylic?
Poly (methyl methacrylate) is the scientific name for the synthetic polymer commonly known as acrylic, acrylic glass, and plexiglass. When not modified it is brittle, transparent, and lightweight. It transmits light and when modified it is available in a wide range of color casting options, textures, and forms.
Is PMMA a thermoplastic?
Polymethylmethacrylate (PMMA) has both thermoplastic and thermosetting polymerplastic properties, depending upon the form in which it is used. PMMA has been modified by cross-linkages and copolymerization to give improved mechanical properties in the sheet form; it is very useful for rigid foot orthoses.
What mean PMMA?
methyl methacrylate
Short for polymethylmethacrylate, or more correctly Poly(methyl methacrylate), PMMA is a clear plastic acrylic material that can be used as a replacement for glass. PMMA is commonly used in places where shatter-proof glass or windows are required, such as the puck barriers found in hockey rinks.
Is PMMA an acrylic?
Is PMMA thermoset or thermoplastic?
PMMA is classified as a “thermoplastic” (as opposed to “thermoset”), and the name has to do with the way the plastic responds to heat. Thermoplastic materials become liquid at their melting point (160 degrees Celsius in the case of Acrylic).
What is made of PMMA?
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.
