Carbon Dioxide Number
The number of grams of KOH equivalent to the carbonate and bicarbonate ions in latex.

One hundredth of a poise, which is a value for viscosity. The viscosity of water at 20°C (68°F) is approximately one centipoise.

Machine for separating by centrifugal force the heavier components from the lighter components of a liquid solution, dispersion, or emulsion.

Centrifuge Latex
Latex, the rubber concentration of which has been increased by centrifuging.

China Clay
Kaolinite, a mineral hydrated aluminum silicate (Al2O32SiO22H2O), a white, mildly reinforcing rubber compounding ingredient.

Chloroform Number
Name given to the method of determining the cure of prevulcanized latex, mixing a portion of chloroform and accessing manually the physical nature of the coagulum produced.

Coating of a coagulant on the surface of former for producing dipped rubber products.

Substance used for causing coagulation. Salts, polyvalent cations such as calcium, acids (including volatile acids like acetic and formic), dehydrating solvents and combinations of these are commonly used as coagulants of latex, for preparing latex dipped goods.

Coagulant Dipping
Process of dipping former into a coagulant. Mainly two processes are used, “Anode” and “Teague”. In the “Anode” process, the former is first dipped into the coagulant, then into the latex compound. In the “Teague” process, the former is dipped first into the latex compound, then into the coagulant. The process may be repeated in either case to build up the desired film thickness. The film is cured on the former after dipping.

An irreversible agglomeration of the dispersed particles of a colloid solution. In rubber latex, clotting together of the dispersed rubber globules to form coherent jelly-like mass.

Piece of rubber formed by coagulation of latex.

Coagulum Content
Term to describe the weight of dry solid material retained when NRL is sieved under standard conditions.

State of matter in which size of the particles is greater than normal molecular dimensions but too small to be seen without the aid of a microscope.

Term used in both latex and dry rubber technologies to denote the mixture (of rubber and additives) from which a rubber product is made.

Process used to produce a compound.

Concentrated latex
Latex, the rubber content of which has been greatly increased by evaporation, creaming, filtration, or centrifuging. It usually contains a small percentage of added preservative or stabilizer such as ammonia, or a protective colloid, to prevent coagulation.

Polymer produced by polymerization of a mixture of two monomers.

Cord Dipping
Process of impregnation of tire cords passing them through rubber latex, and then drying side by side to make a sheet, or by passing them through a solvent solution of rubber and then removing the solvent.

Method of defining the diameter of rubber threads the number of thread-diameters per inch.

Counter Ions
Ions of opposite electrical charge to the absorbed ions in the aqueous phase of latex or dispersion, associated with the latex particle.

Creamed Latex - Cream latex
Latex concentrate produced by creaming process. Creamed latex is normally supplied at a higher TSC value than centrifuged latex e.g. at 66%

Reversible process consisting of gathering by gravitational force, rubber particles surround by serum, near the bottom or near the top of latex.

Continuing extension or flow exhibited by all rubbers held under tensile or compressive force.

Process of bridging individual rubber molecules through the formation of covalent chemical bonds between the rubber molecules.

Cup Lump
Lump of rubber (coagulated field latex) remaining in the tapping cup after emptying out the latex.
