Antistatic agents are also added to some military jet fuels, and to nonpolar organic solvents, to impart electrical conductivity, thus avoid buildup of static charge that could lead to sparks igniting fuel vapors. The static dissipator additive Stadis 450 is the agent added to some distillate fuels, commercial jet fuels, and to the military JP-8.
Static Dissipative Anti-Static Insulative: Description Carbon powders and fiber: No initial charge. Provides path for charge to bleed off. Typically black color. No or low initial charge. Prevents discharge to or from human contact Initial charges are suppressed. Typically pink color. Insulators and Base Polymers. Not an ESD material
AMPS is made by the Ritter reaction of acrylonitrile and isobutylene in the presence of sulfuric acid and water. [2] The recent patent literature [3] describes batch and continuous processes that produce AMPS in high purity (to 99.7%) and improved yield (up to 89%, based on isobutene) with the addition of liquid isobutene to an acrylonitrile / sulfuric acid / phosphoric acid mixture at 40°C.
Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate): A primary antioxidant consisting of sterically hindered phenols with para-propionate groups. Primary antioxidants (also known as chain-breaking antioxidants) act as radical scavengers and remove peroxy radicals (ROO•), as well as to a lesser extent alkoxy radicals (RO•), hydroxyl radicals (HO•) and alkyl radicals (R•).
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge. The word "static" is used to differentiate it from current electricity, where an electric charge flows through an electrical conductor. [1]
For example, antistatic additives can be added to help polypropylene surfaces resist dust and dirt. Many physical finishing techniques can also be used on polypropylene, such as machining . Surface treatments can be applied to polypropylene parts in order to promote adhesion of printing ink and paints.
An antistatic floor mat or ground mat is one of a number of antistatic devices designed to help eliminate static electricity. It does this by having a controlled low resistance: a metal mat would keep parts grounded but would short out exposed parts; an insulating mat would provide no ground reference and so would not provide grounding.
ASA can be used as an additive to other polymers, when their heat distortion (resulting in deformed parts made of the material) has to be lowered. [6] ASA can be coextruded with other polymers, so only the ASA layer is exposed to high temperature or weathering. ASA foils are used in in-mold decoration for forming e.g. car exterior panels. [6]
