  2. Nitrile rubber - Wikipedia

    en.wikipedia.org/wiki/Nitrile_rubber

    A disposable nitrile rubber glove. The uses of nitrile rubber include disposable non-latex gloves, automotive transmission belts, hoses, O-rings, gaskets, oil seals, V belts, synthetic leather, printer's form rollers, and as cable jacketing; NBR latex can also be used in the preparation of adhesives and as a pigment binder.

  3. Philippine units of measurement - Wikipedia

    en.wikipedia.org/wiki/Philippine_units_of...

    A number of units of measurement were used in the Philippines to measure various quantities including mass, area, and capacity. The metric system has been compulsory in the country since 1860, during the late Spanish colonial period. [1]

  4. Nitrile - Wikipedia

    en.wikipedia.org/wiki/Nitrile

    The structure of a nitrile: the functional group is highlighted blue. In organic chemistry, a nitrile is any organic compound that has a −C≡N functional group.The name of the compound is composed of a base, which includes the carbon of the −C≡N, suffixed with "nitrile", so for example CH 3 CH 2 C≡N is called "propionitrile" (or propanenitrile). [1]

  5. Acrylonitrile - Wikipedia

    en.wikipedia.org/wiki/Acrylonitrile

    Its molecular structure consists of a vinyl group (−CH=CH 2) linked to a nitrile (−C≡N). It is an important monomer for the manufacture of useful plastics such as polyacrylonitrile. It is reactive and toxic at low doses. [5] Acrylonitrile is one of the components of ABS plastic (acrylonitrile butadiene styrene). [6]

  6. Micronized rubber powder - Wikipedia

    en.wikipedia.org/wiki/Micronized_Rubber_Powder

    MRP represents an evolution over previous post-manufactured rubber technologies. The most basic rubber processing technology converts end-of-life tire and post-industrial rubber material into rubber chips that are typically one inch or larger in size. These chips are then used in tire-derived fuel and civil engineering projects. [2]

  7. Butyl rubber - Wikipedia

    en.wikipedia.org/wiki/Butyl_rubber

    Butyl rubber gloves. Butyl rubber, sometimes just called "butyl", is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber. Polyisobutylene, also known as "PIB" or polyisobutene, (C 4 H 8) n, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is ...

  8. Tire code - Wikipedia

    en.wikipedia.org/wiki/Tire_code

    These two codes allow one to look up the required cold inflation pressure to carry a given load, according to the load inflation charts or tables. The load tables are too large to include in this article, but may be found at tirepressure.org. [ 9 ] Generally, tire codes with a preceding "P" shall reference the P Metric Tire Load Inflation Chart ...

  9. Nitrile reduction - Wikipedia

    en.wikipedia.org/wiki/Nitrile_reduction

    The mechanism for the reduction of a nitrile to an aldehyde with DIBAL-H. The hydride reagent Diisobutylaluminium hydride, or DIBAL-H, is commonly used to convert nitriles to the aldehyde. [14] Regarding the proposed mechanism, DIBAL forms a Lewis acid-base adduct with the nitrile by formation of an N-Al bond. The hydride is then transferred to ...
