The chemicals used for coating and laminating are polymeric materials, either naturally occurring or produced synthetically. These include natural and synthetic rubbers, polyvinyl chloride, polyvinyl alcohol, acrylic, phenohc resins, polyurethanes, silicones, fluorochemicals, epoxy resins and polyesters." Coating formulations typically include auxiliaries such as plasticizers, adhesion promoters, viscosity regulators, pigments, fillers, flame retardants, catalysts and the like. ...

The single-component plastics and mixed plastics having well-defined composition and known history are best suited for the mechanical recycling. These recyclates can be used to substitute the virgin resins, i.e., they can be reprocessed to have the same functional properties as the comparable virgin materials. Structural heterogeneity s and residual impurities, e.g., different pigments, fillers, flame retardants may be present even in carefully sorted and cleaned recyclates. 

Any additive is a potential source of change to the overall processability from pellet feed to melt rheology. The not uncommon operator comment that one particular color always runs well and another always causes problems is more likely to be fact than superstition. Many products are colored by using masterbatches. whilst extruded products may contain antiblock and slip additives. Injection moldings may contain lubricants to aid mold release or provide product lubrication, e,g., bottle caps. In many cases such nias-terbatches contain low-viscosity polymer waxes to promote additive dispersion (particularly pigments) and masterbatch distribution throughout the natural polymer. There are in fact many additives, including fillers, flame retardants, and antioxidants, that can influence processability.

Incorporation of reinforcing agents and/or fillers, flame retardants, plasticisers, impact modifiers and so on. 

Additive Any substance added to a resin system prior to cure, to induce curing (e.g. catalyst, accelerator) or, to improve properties (e.g. filler, flame retardant). 

Many metals, metal salts and metallic compounds are used as additives in plastics. They are used as stabilizers, pigments, fillers, flame retardants and antistatics. The most commonly used metals are aluminum, titanium, lead, zinc, antimony, tin, chromium, and molybdenum. Nickel, copper and zirconium compounds are used to a lesser degree. 

More recently, additional modifications of nylon 6 (and of other nylons) were produced. Reference is made to grades containing mineral fillers, flame retardants, and toughening agents. Since these developments are still in full swing, they will not be treated here in detail. 

Hame retardant PLA composites have been prepared by adding PLA with various fillers, flame retardants, and other additives. For example, silane-treated metal hydroxides, combined with other additional fillers (talc, mica), are used to produce domestic appliances with flame retardant properties [70].

Besides the use of melamine as a component of intumescent systems it has also been advocated as a flame retardant in its own right. It has the advantages of being inexpensive, readily dispersible in most thermoplastics and is commercially available in grades of varying particle size. The flame retardant effect is largely due to a combination of heat sink effects and vapour phase dilution effects so in these respects it has some similarities with the hydrated filler flame retardants. 

Antioxidants, antistats, fillers, flame retardants, UV screeners, slip agents, metal deactivators, whiteners, pigments, and dye receptors are added to polyolefin powder, chips, or granules prior to fiber manufacture. These additives help to overcome fiber sensitivity to heat, UV radiation, and flame and to improve some other properties. In the melt-in-melt system, PP fiberforming polymers can be mixed with these additives to achieve specific formulations.
