2. Bakelite - Wikipedia

   en.wikipedia.org/wiki/Bakelite

   The first plastic made from synthetic components, it was developed by Leo Baekeland in Yonkers, New York, in 1907, and patented on December 7, 1909. [ 3 ] Bakelite was one of the first plastic-like materials to be introduced into the modern world and was popular because it could be moulded and then hardened into any shape.

3. Ion-exchange resin - Wikipedia

   en.wikipedia.org/wiki/Ion-exchange_resin

   Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.

   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 ...

5. Polycaprolactone - Wikipedia

   en.wikipedia.org/wiki/Polycaprolactone

   PCL beads, as sold for industrial or hobbyist use. Polycaprolactone (PCL) is a synthetic, semi-crystalline, biodegradable polyester with a melting point of about 60 °C and a glass transition temperature of about −60 °C. [2] [3] The most common use of polycaprolactone is in the production of speciality polyurethanes.

6. Expanded polyethylene - Wikipedia

   en.wikipedia.org/wiki/Expanded_polyethylene

   Autoclave expansion is the most common route the bead foam. [4] Butane or pentane is often used as a blowing agent (before 1992 CFCs may have been used). Depending on the specific process uses the beads may be cross-linked either by electron beam irradiation (see Electron beam processing), or by the addition of a chemical agent such as dicumyl ...

7. Polystyrene - Wikipedia

   en.wikipedia.org/wiki/Polystyrene

   Each bead is made of thin-walled, air-filled bubbles of polystyrene. Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam with a normal density range of 11 to 32 kg/m 3. [47] It is usually white and made of pre-expanded polystyrene beads. The manufacturing process for EPS conventionally begins with the creation of small polystyrene ...

9. Polymer clay - Wikipedia

   en.wikipedia.org/wiki/Polymer_clay

   This plasticity is what makes it useful as modeling clay as opposed to putty or paste. Plastigels retain their shape even when heat is applied, which is why polymer clay does not melt or droop when oven cured. [5] Various gelling agents are added to give it this property, such as aminated bentonite, metallic soaps, or fumed silica. [6]
