Polyethylene glycol treated carbon black and compounds thereof

Abstract: A treated carbon black may be produced by treating carbon black with at least one polyethylene glycol having a molecular weight of from about 1,000 to about 1,000,000. The treated carbon black may be used in forming polymeric compositions, such as semi-conductive and insulating compounds, for example for use in electrical cables.

Carbon blacks and compositions incorporating the carbon blacks

Abstract: New classes of carbon blacks which may be broadly characterized as having an Iodine adsorption number (I2No.) of 50-112 milligrams/gram (mg/g) and a primary particle size measured in accordance with the procedures in ASTM Test Procedure D3849-89 (hereinafter denoted as 'primary particle size') of less than or equal to 25 nanometers (nm). Certain of the carbon blacks of the present invention may be further characterized as having a CDBP (dibutyl absorption value of the crushed carbon black) of less than or equal to 102 cubic centimeters DBP per 100 grams of carbon black (cc/100g). The present invention provides carbon blacks having I2No. of 65-95 mg/g and a primary particle size of less than or equal to 20 nm. Also disclosed and claimed are carbon blacks having an I2No. of 100-112 mg/g and a primary particle size of less than or equal to 20 nm. The present invention further provides carbon blacks having an I2No. of 65-112 mg/g; a primary particle size of less than or equal to 20 nanometers (nm); and a CDBP (dibutyl absorption value of the crushed carbon black) of less than or equal to 102 cubic centimeters DBP per 100 grams of carbon black (cc/100g). In addition, carbon blacks having an I2No. of 50-70 milligrams/gram (mg/g) and a primary particle size of less than or equal to 25 nm, are disclosed and claimed. The present invention also provides carbon blacks having an I2No. of 50-85 mg/g; a primary particle size of less than or equal to 25 nm; and a CDBP of less than or equal to 96 cc/100g. The carbon blacks are particularly well suited for use in the production of polymer compositions. Also described and claimed are polymer compositions incorporating the new carbon blacks.

Aerogel blanket and method of production

Abstract: A method of making a nonwoven wet laid aerogel blanket is provided. The aerogel blanket can exhibit improved thermal conductivity, lower corrosivity, lower dust production and a uniform structure. The blanket can be made from an aerogel floc that is formed from a slurry of aerogel particles.

Printing plates comprising modified pigment products

Abstract: The present invention discloses printing plates comprising a substrate and a radiation-absorptive layer, wherein the radiation-absorptive layer comprises at least one modified pigment product. The modified pigment product comprises a pigment having attached at least one organic group and at least one amphiphilic counterion. Methods of imaging printing plates are also disclosed.

Aggregates having attached polymer groups and polymer foams

Abstract: An aggregate having attached at least one type of polymer is described, wherein the aggregate comprises at least one carbon phase and at least one silicon-containing species phase. Other aggregates which can have a polymer attached include, but are not limited to, an aggregate comprising at least one carbon phase and at least one metal-containing species phase and carbon black at least partially coated with silica. Methods of making the aggregate are further described which involve combining the starting aggregate with a reactive polymer and mixing in order to attach the polymer onto the aggregate. Uses of the aggregate are further described such as incorporating the aggregate into polymer foams and other polymeric products as well as elastomeric products. Polymer foam compositions are also described and contain polymer foam and chemically modified carbonaceous filler, specifically, carbonaceous filler having polymer moieties chemically bonded to the carbonaceous particulates. Exemplary carbonaceous fillers include carbon black, activated carbon, graphite, carbon fibers, fibrils and the like. The polymer moieties have a valence orbital bond to the carbonaceous particulate, such as an ionic or covalent bond. The chemical bond survives shear forces and the like, such as would be encountered by filler material in a reaction injection molding process for the manufacture of filled polyurethane foam insulation panels.
