What are process additives?
Definition. An additive process is a generalization of a Lévy process obtained relaxing the hypothesis of identically distributed increments. Thanks to this feature an additive process can describe more complex phenomenons than a Lévy process.
What is polymer processing additives?
Additives are chemicals added to the base polymer to improve processability, prolong the life span, and/or achieve the desired physical or chemical properties in the final product. Once the additives are added, the polymer blend is referred to as a masterbatch and is processed accordingly.
Which additive is used during processing?
Additives such as salt, spices, and sulfites have been used since ancient times to preserve foods and make them more palatable….Processing agents.
function | typical chemical agent | typical product |
---|---|---|
anticaking | sodium aluminosilicate | salt |

What is polymer processing?
“Polymer Processing” may be defined as the manufacturing activity of converting raw polymeric materials into finished products of desirable shape, microstructure and properties. Table 1 summarizes processing methods applicable to thermoplastics and thermosets, as well as methods common to both types of materials.
How are processing additives used in the plastics industry?
Processing additives from BYK are used in a number of plastics applications. These additives have generally positive influences on a wide range of processing parameters and the properties of the final product. These include, for example: – Reducing VOC emissions and odors
Why are polymer additives used in electrical products?
These additives are common in electrical products to avoid the ignition and burning of plastics. Flame retardants can be mixed with the base polymer, or added during the plastic processing step, or even as a surface layer finish on the final product.
What are the different types of food additives?
There are four general categories of food additives: nutritional additives, processing agents, preservatives, and sensory agents. These are not strict classifications, as many additives fall into more than one category.
How are processing aids used in food production?
Processing aids are substances or additives of natural or synthetic origin used in the production of foods. They are commonly used in a wide variety of products including bakery, confectionery, jams, jellies, meat and produce.
