Conductive Plastic/Polymer AdditivesIntroduction:Plastics and polymers are inherently low in thermal and electrical conductivity. For this reasonappliions that require conductive properties, which could also benefit from the use of polymercomponents because of their light weight, high strength/weight ratio, easy moldability, etc, cannottake advantage of this desirable material.
Summary CP Coke (Calcined petroleum coke) is a high purity carbon material produced by heating green petroleum coke to drive off moisture, volatile matter, and impurities and to increase its electrical conductivity. Nearly 75% of Calcined petroleum coke is used in
The presence and characteristics of a connected network of polyaniline (PANI) within a composite coating based on polyester acrylate (PEA) has been investigated. The bulk electrical conductivity of the composite was measured by impedance spectroscopy. It was found that the composite films containing PANI have an electrical conductivity level in the range of semiconductors (order of 10–3 S cm
Graphite Electrodes Composition From above description, we can know that graphite electrode for sale is mainly regarding petroleum coke, needle coke, coal tar pitch as its raw materials. So I will describe them in detail. Petroleum Coke Petroleum coke is a kind of
Five Coke Breeze Backfills Asbury 218-L Backfill is an industry standard calcined petroleum coke. It is a perfect choice in situations where backfill must be top loaded. The density and angular nature of Asbury 218-L allow it to settle quickly into position. Asbury 218
Artificial graphite (nongraphitic carbon) is fabried by heat treatment of petroleum coke, coal-tar pitch, or oil. Specific capacity and reversibility is lost at high temperatures from 1000 Ah kg −1 (at 500 C) to 150 Ah kg −1 (1800 C). Above 2000 C, an increasing
Operating parameters are controlled to impart the required crystal structure, density and electrical conductivity. The calcined coke is first cooled by water quenching the red-hot material, and then further cooled by natural draft air as it tules through the length of the cooler, on its way to the conveyors leading to storage in the godowns.
Silicon Carbide (SiC) is produced from quartz sand, petroleum coke and charcoal etc in high temperature electric resistance furnaces. Silicon carbide has excellent properties with good electrical & thermal conductivity and high abrasive resistance.
petroleum coke, which is a byproduct of oil refining. The electrodes used in metal smelting industry because of the sponge-like structure which improves the contact between electrode and metal. The electrical conductivity of the CPC material is strongly
Green pellets (GPs), prepared at different compression pressures (cs = 6, 7.5 and 12 metric tonne) from mixtures containing self-adhesive carbon grains (sacg) from the oil palm empty fruit bunch (EFB) and different percentages (pr = 0 to 90%) of a non self-adhesive powder of petroleum green coke (ppgc), were carbonized (800° C) and activated with CO2 to produce carbon pellets (CPs
Petroleum coke is a by-product of the coker process that occurs in the oil industry. Also known as "green petroleum coke", calcined petroleum coke is very important to link the oil and metallurgical industries for multiple appliions. ''s experience in petroleum
Nitrogen‐fluidized beds of petroleum coke and graphite were heated by applying an a.c. voltage to electrodes submerged in the bed. Bed resistivities, calculated from the voltage and power input required to maintain a constant temperature, show a similar decrease in

Graphite and Coke Graphite finds wide appliion thanks to its favourable coination of properties such as: • low friction, chemical inertness and absence of inherent abrasiveness; • high thermal conductivity, thermal stability and electrical conductivity; • •
Carbon-containing compounds have some electrical conductivity and are therefore antistatic. CARBON Base: Amorphous petroleum-coke Purity: > 99% C Particle size: < 75 µm Density: 1.8 E-CARBON Base: partly graphitised coke Purity: > 99% C 1.8
Calcined petroleum coke is one type of coke product, which is produced by the green petroleum coke under 1300 , then will make the volatile matter, moisture and other impurities less. For the green coke, the carbon content is more than 80%, and the volatile matter can reach 11% more or less, after the high temperature, the carbon content can reach 98.5%min, and the volatile matter will be much
