Graphite foam from pitch and expandable graphite

Carbon, 2014
Graphite foams were prepared from a coal tar pitch that was partially converted into mesophase. Expandable graphite was used instead of an inert gas to "foam" the pitch. The resulting foam was subjected to a series of heat treatments with the objective of first crosslinking the pitch, and thereafter carbonizing and graphitizing the resulting foam.

Densification of expanded graphite

Carbon, 2002
A brief theoretical investigation of the behavior of exfoliated graphite (EG) undergoing compaction is presented. Simple arguments and assumptions allow one to calculate the density of the initial individual worm-like particles of EG for any final porosity of the resultant consolidated blocks. These results as well as excluded volume considerations are

Performance of expanded graphite and expanded milled‐graphite fillers in thermosetting resins

Polymer Composites, 2005
AbstractEpoxy/expanded graphite (EG) and polyester/EG composites were prepared with the aid of sonication, while epoxy/expanded‐milled graphite (epoxy/milled‐EG) and polyester/expanded‐milled graphite (polyester/milled‐EG) composites were prepared on a three‐roll paint mill.

Synergistic fire retardant effect between expandable graphite and ferrocene-based non-phosphorus polymer on polypropylene

, 2020
The key point to enhance the flame retardancy of expandable graphite (EG) in polymeric materials is to weaken the excessive intumescence of EG during combustion.

Synergistic effect of expandable graphite and phenylphosphonic-aniline salt on flame retardancy of rigid polyurethane foam

, 2020
In this work, rigid polyurethane foams (RPUF) were flame retarded by adding 8 wt % expandable graphite (EG) and EG/Phenylphosphonic-aniline salt (FR1) flame retardant compounds. The adding amount of EG/FR1 compound is 8 wt % as well, and different ratios

Preparation and characterization of phenolic foam reinforced with expandable graphite and expanded graphite

Journal of Cellular Plastics, 2017
In this paper, two kinds of phenolic foams modified with expandable graphite and expanded graphite were prepared and the effect of particles on the mechanical properties and structure of the foams has been discussed. The mechanical properties, density and morphology of reinforced phenolic foams were studied.

Synthesis of a novel phosphorus and nitrogen-containing flame retardant and its application in rigid polyurethane foam with expandable graphite

, 2020
A novel phosphorus and nitrogen containing flame retardant named 1,4-bis(Diethyl methylenephosphonate) piperazine (BDEMPP) was synthesized. The chemical structures of BDEMPP were determined by Fourier transform infrared spectrum (FTIR), nuclear magnetic ...
