Glossary

Compounding material used in small amounts with vulcanizing agent to increase the speed of vulcanization and enhance physical properties of the vulcanizate.

Criteria agreed between vendor and purchaser, regarding the proportion of permissible defective items within a consignment without causing rejection.

Compounding material used in small proportion to increase the effectiveness of an accelerator.

Continuation of the process of vulcanization after the energy source has been removed.

Vulcanization at ordinary room temperature or without the aid of heat.

The layer of latex compound applied to the back of tufted carpet to secure the tufts to the backing fabric. Generally this coating is based on CSBR latex with large amount of added filler.

Term for the coagulant dipping process where the former is first dipped into the coagulant, then into the latex compound.

Material that prevents latex gelling. Ammonium hydroxide and other basic substances are anti-gelling agents of latex.

Material used to reduce the surface tack of latex products; usually, but not necessarily powders.

Additive used to reduce web formation in latex dipping.

Substance that prevents the coagulation of a colloid suspension or emulsion.

Chemical added to a liquid mix to prevent formation of foam, or added to the foam itself to break the foam already formed. Long chain saturated alcohols containing 6 to 18 carbon atoms and emulsions of certain silicone polymers are principal antifoams used.

Compounding material used to retard deterioration caused by oxidation.

Term to denote latex prepared by dispersing a preformed polymer in an aqueous medium to distinguish from synthetic latex made by emulsion polymerization.

Type of grinding machine used for the preparation of aqueous dispersions. The grinding action is provided by an impeller stirring the gravel grinding medium. Attritors are faster in their grinding action than standard ball mills.

Pressure vessel used for vulcanizing rubber products by means of steam under pressure.
