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
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•).
EBS is a synthetic wax used as a dispersing agent or internal/external lubricant for benefits in plastic applications to facilitate and stabilize the dispersion of solid compounding materials to enhance processability, to decrease friction and abrasion of the polymer surface, and to contribute color stability and polymer degradation.

Hindered amine light stabilizers (HALS) are chemical compounds containing an amine functional group that are used as stabilizers in plastics and polymers. [1] These compounds are typically derivatives of tetramethylpiperidine and are primarily used to protect the polymers from the effects of photo-oxidation; as opposed to other forms of polymer degradation such as ozonolysis.
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.
Americhem manufactures color and additive masterbatches (also known as concentrates) for use in the plastics and synthetic fibers industries. Most of the company's products are made for specific customers and specific applications. Americhem also makes single pigment dispersions, which are used as a stand-alone product or as a mix.
