Anti-static

It is believed that to avoid any risk of explosion, the electrical conductivity of jet fuel should fall between 50 and 450 pS/m. This level is attained using anti-static additives which are metallic salts (chromium, calcium) added at very low levels on the order of 1 ppm.

Electricity at rest as opposed to moving or current electricity. Static electricity can build up on the surface of insulating materials and may either spark across to an adjacent object or give a shock to anyone handling the material. See Anti-Static Rubber.

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. 

The main current products in the field of biopolymers are (a) composite materials for special and high quality performance applications, (b) fashion and comfort/hygiene where their silky feel, breath ability and anti-static characteristics create a value over and above the environmental aspects (e.g., sports wear... 

To avoid risks of electrostatic charging (sparks, explosions) anti-static additives are sometimes added to a polymer also carbon black may be used (see MT 8.2.1). 

Anti-Static Additive - dissipates static charge in jet fuel. Static charge buildup can result in unwanted ignition of jet fuel/air mixtures. Use is normally not permitted in aviation gasoline except in Canada and Britain. Use is permitted in civil jet fuel and mandatory in military jet fuel. 

Protective Garments While working with explosives and toxic materials, workers must wear approved coveralls or laboratory coats (preferably full length) to prevent contamination of their personal apparel. The use of flame-retardant coveralls is desirable for some explosive operations where there is a possibility of a flash. Cotton or other anti-static material should be worn wherever there is a possibility of generation of static electricity.

Rubbers are usually electrically insulating and this property is widely exploited in cables and various components in electrical appliances. They can also be made anti-static and even conducting by the addition of suitable carbon blacks. In all cases, it is the combination of the electrical properties and the inherent flexibility of rubbers which makes them attractive for particular applications. 

Resistance or resistivity is by far the property most often measured. For anti-static and conductive rubbers, only resistivity and surface charge, measurements are useful because such rubbers would not be used in situations requiring low dielectric loss or involving high voltages. 

On anti-static and conducting products, it is usual to measure the resistance between specified points. More or less efficient electrode systems are used, contact resistance included and the resistance usually measured with a commercial insulation tester. The relevant international method is ISO 287820. This used to be used in conjunction with two specifications (ISO 2882 and 2883) for antistatic and conductive products and, consequently, had procedures detailing the electrodes to be used for the products in those standards. ISO 2882 and 2883 were withdrawn, largely because of no...

Softeners and Anti-stats. A recent formulation trend is to incorporate fabric care benefits, such as softening and anti-static properties, into textile cleaning products in both powder and liquid fomi.

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...
