    en.wikipedia.org/wiki/Poly(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 . This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can ...

    Faraday Wax is a malleable dark red solid with a low melting point. Joints can be made with Faraday Wax via heating the two surfaces to be joined, then press the wax against the heated surfaces similar to soldering. These joints are suitable down to 10 −7 mbar [9] and can be made between glass and metal.

  4. Vacuum forming - Wikipedia

    en.wikipedia.org/wiki/Vacuum_forming

    The vacuum forming helps tie the individual pieces together and make one mold out of many pieces that can easily be replicated. From there plaster, concrete, etc. can be cast into the plastic form. Wood patterns are a common material to vacuum form as it is relatively inexpensive and allows the customer to make changes to the design easily.

    A wide range of colors can be achieved by dyeing of the surface or the bulk of the material. CR-39 is also resistant to most solvents and other chemicals, gamma radiation, aging, and to material fatigue. It can withstand the small hot sparks from welding, something glass cannot do. It can be used continuously in temperatures up to 100 °C and ...

    Optical glass refers to a quality of glass suitable for the manufacture of optical systems such as optical lenses, prisms or mirrors.Unlike window glass or crystal, whose formula is adapted to the desired aesthetic effect, optical glass contains additives designed to modify certain optical or mechanical properties of the glass: refractive index, dispersion, transmittance, thermal expansion and ...

  8. Acrylic resin - Wikipedia

    en.wikipedia.org/wiki/Acrylic_resin

    Acrylic resin is a common ingredient in latex paint (UK: "emulsion paint"). Latex paints with a greater proportion of acrylic resin offer better stain protection, greater water resistance, better adhesion, greater resistance to cracking and blistering, and resistance to alkali cleaners compared to those with vinyl.

  9. Thermoforming - Wikipedia

    en.wikipedia.org/wiki/Thermoforming

    Its simplified version is vacuum forming. In its simplest form, a small tabletop or lab size machine can be used to heat small cut sections of plastic sheet and stretch it over a mold using vacuum. This method is often used for sample and prototype parts. In complex and high-volume applications, very large production machines are utilized to ...
