  4. Blowing agent - Wikipedia

    en.wikipedia.org/wiki/Blowing_agent

    The bubble/foam-making process is irreversible and endothermic, i.e. it needs heat (e.g. from a melt process or the chemical exotherm due to cross-linking), to volatilize a liquid blowing agent. However, on cooling process, the blowing agent will condense, which is a reversible process. [2] [3]

  5. Desoldering - Wikipedia

    Another way to remove these devices is to use Field's metal, an alloy which melts at around 140 °F (62 °C), lower than the boiling point of water. The metal is melted into the solder joints of the device, where it remains liquid even once cooled down to room temperature, and the chip can simply be lifted off the board.

Rubber cement (cow gum in British English) is an adhesive made from elastic polymers (typically latex) mixed in a solvent such as acetone, hexane, heptane or toluene to keep it fluid enough to be used.

  7. Sulfur vulcanization - Wikipedia

    en.wikipedia.org/wiki/Sulfur_vulcanization

    Worker placing a tire in a mold before vulcanization. Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of varying hardness, elasticity, and mechanical durability by heating them with sulfur [1] or sulfur-containing compounds. [2]

  9. Polymer stabilizer - Wikipedia

    en.wikipedia.org/wiki/Polymer_stabilizer

    Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate): A primary antioxidant consisting of sterically hindered phenols with para-propionate groups. Primary antioxidants (also known as chain-breaking antioxidants) act as radical scavengers and remove peroxy radicals (ROO•), as well as to a lesser extent alkoxy radicals (RO•), hydroxyl radicals (HO•) and alkyl radicals (R•).
