A transparent thermoplastic material produced by the polymerization of methyl methacrylate monomer.

CONT

Poly(methyl methacrylate)(PMMA) is by far the predominant polymethacrylate used in rigid applications because it has crystal clear transparency, excellent weatherability(better than most other plastics), and a useful combination of stiffness, density, and moderate toughness.

CONT

Major applications of PMMA include: automotive industry - rear lamps, light fixtures; acrylic sheet - bathtubs; glazing – signs; composites - sinks, basins and bathroom fixtures; contact lenses; bone cements; membrane for dialysis; dental restorations; road lines.

  • Crop Protection

DEF

Paints consisting of copolymers designed to be smoothed via erosion of their surface as the vessel moves through the water, continually exposing smooth, fresh paint.

CONT

Self-polishing copolymer (SPC) antifoulings release biocides via a hydrolysis reaction of an acrylic polymer with seawater. This is a chemical reaction and only occurs at the surface of the coating. SPC technology combines controlled polishing rate and optimum biocide release with inherent self-smoothing for hull roughness control and maximum fuel efficiency.

OBS

"Controlled solubility copolymers" or "self-polishing copolymers(SPC) "are modern coatings in which, initially for TBT [tributyltin] paints, the biocide was chemically part of the paint matrix or resin, for example the copolymer tributylin methacrylate. When immersed, hydrolysis caused the copolymer to cleave, or hydrolyse, splitting the copolymer into a TBT(the biocide) and an acrylate(the resin) component. The TBT then released and acted as a biocide, the acrylate dissolved to ablate the paint. TBT-free SPCs have now been developed which use copper, zinc or silyl acrylate copolymers.

Treating patients with vertebral fractures... First, the patient is given a local anesthetic. Then using a technique called percutaneous vertebroplasty, a needle is inserted into the spine at the area of the fracture. Doctors use imaging techniques, such as CT scanning and fluoroscopy, to guide placement of the needle during the procedure. Under continued radiographic guidance, the methyl methacrylate is slowly injected into the vertebral space. Then, the needle is withdrawn. Shortly after injection, the epoxy hardens within the spine.

Kyphoplasty is a newer treatment for patients immobilized by the painful vertebral body compression fractures associated with osteoporosis. Like vertebroplasty, kyphoplasty is a minimally invasive procedure that can alleviate up to 90% of the pain caused by compression fractures. In addition to relieving pain, kyphoplasty can also stabilize the fracture, restore height, and reduce deformity.... Kyphoplasty is performed under local or general anesthesia. Using image guidance x-rays, two small incisions are made and a probe is placed into the vertebral space where the fracture is located. The bone is drilled and a balloon, called a bone tamp, is inserted on each side. These balloons are then inflated with contrast medium(to be seen using image guidance x-rays) until they expand to the desired height and removed. The balloon does not remain in the patient. It simply creates a cavity for the cement and also helps expand the compressed bone. The spaces created by the balloons are then filled with PMMA [poly(methyl methacrylate) ], the same orthopaedic cement used in vertebroplasty, binding the fracture. The cement hardens quickly, providing strength and stability to the vertebra, restoring height, and relieving pain.

À la différence de la vertébroplastie, la cyphoplastie est caractérisée par l'utilisation de ballonnets avant l'injection de ciment. Les ballonnets sont insérés dégonflés dans la vertèbre à traiter. Les ballonnets sont ensuite gonflés avec un produit de contraste radio-opaque. Les ballonnets repoussent l'os spongieux fracturé sur les bords de la vertèbre tassée et créent ainsi une cavité au sein du corps vertébral. Un manomètre digital permet au radiologue de contrôler la pression interne des ballonnets. Lorsque la pression maximale est atteinte, une phase de maintien de la pression permet de créer la cavité, puis les ballonnets sont dégonflés et retirés. Un ciment acrylique visqueux PMMA [poly(méthacrylate de méthyle)] est alors injecté à basse pression dans la cavité.

Resin impression tray material is a device intended for use in a two-step dental mold fabricating process. The device consists of a resin material, such as methyl methacrylate, and is used to form a custom impression tray for use in cases in which a preformed impression tray is not suitable, such as the fabrication of crowns, bridges, or full dentures. A preliminary plaster or stone model of the patient's teeth and gums is made. The resin impression tray material is applied to this preliminary study model to form a custom tray. This tray is then filled with impression material and inserted into the patient's mouth to make an impression, from which a final, more precise, model of the patient's mouth is cast.

Subject field(s)
  • Packaging in Plastic

DEF

An additive, such as polyethylene, cellulose acetate butyrate, poly(vinyl acetate), polyurethane, polycaprolactone, and poly(methyl methacrylate), incorporated during the fabrication of(mainly) polyester films to assure a smooth surface.

CONT

Internal slip agents ... are added to give the film its final slip characteristics for the particular end use.

OBS

The frictional properties of a film are important when the film comes into contact with metal surfaces such as "ploughs", formers, guides, etc., which are used to preform tubes or to fold the wrapping material round the product. High slip (low coefficient of friction) is desirable in these situations.
