Anti-static agents

EASTERN COLOR CHEMICAL CO. Anti-Static Agents  

A moderately durable anti-static agent, cationic in nature and completely soluble in water for application purposes. With moderate to fairly high drying temperatures, this leaves the residue as a durable antistatic material remaining. This material, of course, is useful on synthetic fibers in general and will not impair the tensile strength of the fabric. 

This material is a cationic anti-static agent which will provide some softening as well as excellent static inhibition. This product is designed for synthetic as well as natural fibers and blends. 

This material is a nonionic, 100% active antistatic material designed for general antistatic use. This material is recommended for use on synthetic fibers as well as for the processing of wool where processing oils and emulsions are also present. ECCOSTAT P would be in the non-durable category of antistatic agents. 

This material is a durable antistatic agent, cationic in nature, and compounded to give excellent antistat properties on all synthetic fabrics and fibers. This is especially useful on either woven or non-woven materials. Moderate to high drying temperatures, here again, will produce some degree of durability.

Cationic surfactants are used widely as fabric softeners, anti-static agents, antiseptic components and as the main ingredients in rinse conditioner products. However, there is little data on their occurrence in wastewater and removal during wastewater treatment. The concentrations of some cationic surfactants and their biodegradation intermediates, found in WWTP influents and effluents, are listed in Table 6.1.3. 

Impregnation with anti-static agents, although this is not a feasible solution if high and permanent conductivity is required. 

Differences between the ingredients in a formulation may be essentially of a chemical nature, but also may be physical (such as the ranges of particle sizes)—and quite often both chemical and physical variations are found in practice. In order to match a particular material consistently it is not sufficient merely to know even the precise formulation in terms of polymer, plasticizer, heat stabilizer, filler, anti-static agent, colour, and so forth each of the components in the formulation must be supplied consistently to a tight... 

Even without heating it is likely that in the course of each pass there will be some release of volatile material—like water vapour, plasticizer, extender, or processing aids (anti-static agent or lubricant). There must be opportunity for such substances to be vented and carried away the die or tool must be capable of resisting attack by volatiles (suitably plated if they are corrosive), and designed to prevent an accumulation of released materials. Special hardened... 

Until fairly recently most plastics were purchased fully compounded in the colour required for moulding or extrusion, but with a view to offering ranges of colours more cheaply and conveniently it is quite usual now for machines to be fed with blends of natural thermoplastic and masterbatch—a convenient wax-like base containing appropriate concentrations of colorant and other additives (such as anti-static agent). The supply of masterbatches has become an important specialized business. 

Many formulations include suitable anti-static agents, which migrate gradually to the surface and so reduce the surface resistivity. Dispersal of static electric charges by this means is beneficial over the long term for the appearance of the articles (since dust is less likely to collect on them) but the presence of additives of this nature can necessitate some changes in moulding practice. 

Once formed the plastic article may be polymerized further at a later stage, or cross-linked to meet a particular specification. Often plastics are modified by additives that serve their purpose only at the surface of an article—such as anti-static agents that help prolong the pristine condition of the item in dirty atmospheres.

Some of these polymers are thermally stable, some have high molecular weight (150000), some are soluble in organic solvents, some are fusible, some can be cast into films. These polymers have been suggested as viscosity stabilizers for oil, grease thickners, anti-static agents, and corrosion resistant coating for metals. 

During or at the end of the EPS production, a number of additives can be incorporated to improve process and application properties. Additives can include nucleation agents, flame retardants, fast-cool agents, anti-lump and anti-static agents, stabilizers, plasticizers, pigments, etc. Some of the more important additives and their functions are described in more detail below. 

A nonionic, water soluble, highly efficient anti-static agent. This material is particularly effective in processing synthetic fabrics and fibers, and may be applied at low concentrations to obtain satisfactory static protection. In addition, this product would also serve to aid in lubricity in fiber processing.

Anti-static agent, lubricant, and softener compatible with resin finishes. 

In addition to the straightforward application of conductors and semi-conductors, there are some interesting examples of other uses. Polymers derived from 3,4-ethylenedioxythiophene are produced commercially as anti-static agents and substituted compounds have found particular application in electrochromic devices - substances that change colour on application of an electric current. 

Removal of surface acting substances from plastics, e.g. lubricants, slip additives, such as stearamide, stearates, anti-static agents.
