Abstract:
A polymer composition and fiber, film or sheet prepared therefrom, which contains (i) an olefin polymer containing an acid neutralizing agent other than a metallic salt of a saturated or unsaturated fatty acid, and ii) a stabilizer system distributed throughout the polymer, the stabilizer system including (a) a phosphite selected from 2,2',2"-nitrilo�triethyl-tris(3,3',5,5'-tetra-tert.butyl-1,1-biphenyl-2,2'-diyl)phosphite! and tris(2,4-di-tert-butylphenyl) phosphite; and (b) a N,N-dialkylhydroxylamine. Also disclosed is a method for preparing a polyolefin fiber, film or sheet, which includes adding the above stabilizer to an olefin polymer containing an acid neutralizing agent other than a metallic salt of a saturated or unsaturated fatty acid, thereby producing a stabilized olefin polymer; and extruding the stabilized olefin polymer through a die.
Abstract:
A method of applying a coating composition to a substrate utilizing a high transfer efficiency applicator include the steps of providing the high transfer efficiency applicator comprising an array of nozzles wherein each nozzle defines a nozzle orifice having a diameter of from 0.00002 m to 0.0004, providing the coating composition, and applying the coating composition to the substrate through the nozzle orifice without atomization such that at least 99.9% of the applied coating composition contacts the substrate to form a coating layer having a wet thickness of at least 5 microns, wherein the coating composition includes a carrier, a binder, and a radar reflective pigment or a LiDAR reflective pigment. The coating composition has an Ohnesorge number (Oh) of from about 0.01 to about 12.6, a Reynolds number (Re) of from about 0.02 to about 6,200, and a Deborah number (De) of from greater than 0 to about 1730.
Abstract:

The polyetherpolyol includes polytetrahydrofuran with a number average molecular weight of the polyetherpolyol between 1.3×103 g/Mot and 1.8×103 g/Mol, and the e-modulus of the composition determined according to DIN EN ISO 527 is between 0.1×103 MPa and 10×103 MPa.
Abstract:
The invention relates to an article having a single- or multi-layered main body having elastic properties, in particular an air spring bellows, a metal-rubber element or a vibration damper. In order to improve its flame retardant properties, the main body of the article consists of or contains at least one layer D constructed from a rubber mixture which is free from halogen-containing flame retardants and contains at least one carbon black having a BET surface area according to DIN-ISO 9277 between 35 and 140 m2/g and an oil absorption number (OAN) according to ISO 4656 between 70 and 140 ml/100 g and a first aluminum trihydrate (ATH_1) and at least a further aluminum trihydrate (ATH_2), wherein the first aluminum trihydrate (ATH_1) and the further aluminum trihydrate (ATH_2) each have a different particle size.
Abstract:
A sealant composition of the present invention is formed by blending, per 100 parts by mass of a rubber component (A), 5 parts by mass or more of a tackifier (B), 60 parts by mass or more of a plasticizer (C), 0.1 to 10 parts by mass of sulfur (D), and 0.1 to 10 parts by mass of a vulcanization accelerator (E) (excluding a thiuram-based vulcanization accelerator, however), and thus the sealant composition can provide improved sealability, viscosity temperature dependency, and fluidity during storage of a tire.
Abstract:
The present invention relates to an organic filler, wherein a covalent bonding of at least one organic modifier to the organic filler has been effected (i) at least via a part of the oxygen atoms of at least one functional group of the filler which is selected from phenolic OH groups, phenolate groups, aliphatic OH groups, carboxylic acid groups, carboxylate groups and mixtures thereof and/or (ii) at least via a part of the carbon atoms of the filler that are in ortho position with regard to phenolic OH groups and/or phenolate groups, a rubber composition comprising at least one rubber and at least the filler mentioned hereinabove, a vulcanizable rubber composition that additionally comprises a vulcanization system, a vulcanized rubber composition obtainable therefrom, as well as a use of the filler mentioned hereinabove for the production of (vulcanizable) rubber compositions for employment in the production of tires, preferably pneumatic tires and solid tires, preferably for their tread, sidewall and/or inner liner, respectively, and/or for employment in the production of technical rubber articles, preferably profiles, seals, dampers and/or hoses.
