2. Bakelite - Wikipedia

   en.wikipedia.org/wiki/Bakelite

   Bakelite (/ ˈbeɪkəlaɪt / BAY-kə-lyte), formally poly­oxy­benzyl­methylene­glycol­anhydride, is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. The first plastic made from synthetic components, it was developed by Leo Baekeland in Yonkers, New York, in 1907, and patented on ...

3. Thermosetting polymer - Wikipedia

   en.wikipedia.org/wiki/Thermosetting_polymer

   Thermosetting polymer. In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (resin). [1] Curing is induced by heat or suitable radiation and may be promoted by high pressure or mixing with a catalyst.

4. Resin casting - Wikipedia

   en.wikipedia.org/wiki/Resin_casting

   Resin casting is a method of plastic casting where a mold is filled with a liquid synthetic resin, which then hardens. It is primarily used for small-scale production like industrial prototypes and dentistry. It can be done by amateur hobbyists with little initial investment, and is used in the production of collectible toys, models and figures ...

5. Poly(methyl methacrylate) - Wikipedia

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   Poly (methyl methacrylate) (PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic, and it is a transparent thermoplastic. 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).

6. Polyoxymethylene - Wikipedia

   en.wikipedia.org/wiki/Polyoxymethylene

   Polyoxymethylene (POM), also known as acetal, [ 4 ]polyacetal, and polyformaldehyde, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. Short-chained POM (chain length between 8 and 100 repeating units) is also better known as paraformaldehyde (PFA).

7. Superhard material - Wikipedia

   en.wikipedia.org/wiki/Superhard_material

   Superhard material. A superhard material is a material with a hardness value exceeding 40 gigapascals (GPa) when measured by the Vickers hardness test. [1][2][3][4] They are virtually incompressible solids with high electron density and high bond covalency. As a result of their unique properties, these materials are of great interest in many ...
