as BHT Inhibitor. |
| DEF |
Diesel Exhaust Fluid - DEF is a
colorless and non-toxic solution of 67.5 percent water and 32.5 percent
automotive-grade urea. The U.S. Environmental Protection
Agency (EPA) classifies DEF as “non-hazardous.” |

| NOx |
(often written NOx) refers
to NO (Nitric Oxide; Nitrogen Monoxide) and NO2 (Nitrogen Dioxide). Gas produced
during combustion, especially at high temperature. |
| OGM |

useful as synthetic lubricants such as synthetic motor
oils for vehicles; can be used over a wide temperature range. |
| Paraffinic Base Oils |
A characterization of certain
petroleum products prepared from paraffinic type crudes (crudes containing a
high percentage of straight chain aliphatic hydrocarbon molecules).
Lubricating oils made from these crudes are normally distinguished from
similar oils from other crudes by higher API gravity and higher viscosity
index. |
| PEL |

| PGE |
Polyglycol-ester |
| PIB |
Polyisobutylene or polyisobutene
--added in small amounts to the lubricating oils used
in machining to provide a significant reduction in the generation
of oil mist, thus reducing the operator's inhalation of oil mist. |

compound added to Antifreeze/Coolant to extend its useful life and improve
performance. |
| SCR |
Selective Catalytic Reduction -
used in diesel truck engines, is a means of converting nitrogen oxides,
also referred to as NOx, with the aid of
a catalyst into diatomic nitrogen, N2,
and water, H2O. The selective catalytic reduction (SCR) is an
after-treatment system composed of a supply module, a diesel exhaust fluid
(DEF) tank, a dosing module and an SCR catalyst. |

| Transformer Oil |
Also called Insulating
Oil. A highly-refined mineral oil that is stable at high
temperatures and has excellent electrical insulating properties. It is used
in oil-filled transformers, some types of high
voltage capacitors, fluorescent lamp ballasts, and some types of
high voltage switches and circuit breakers. Its functions are
to insulate, suppress corona and arcing, and to serve as
a coolant. |
