Abstract:
A tire comprises a rubber composition based on at least one diene elastomer, a reinforcing filler predominantly comprising silica, a crosslinking system, and a primary amine of formula (I): R—NH2 (I), in which R represents a linear or branched hydrocarbon group comprising from 8 to 24 carbon atoms. The rubber composition is essentially devoid of guanidine derivative.
Abstract:
A tire comprises a rubber composition based on at least one diene elastomer, a reinforcing filler predominantly comprising silica, a crosslinking system, and a hydroxyalkylpiperazine of formula (I): in which R1 represents a linear or branched alkyl group comprising from 1 to 18 carbon atoms, R2 represents a linear or branched alkylene group comprising from 1 to 18 carbon atoms, it being understood that R1 and R2 can bear one or more additional hydroxyl groups. The rubber composition is essentially devoid of guanidine derivative.
Abstract:
The present invention relates to new improved adhesives for binding books and related articles and the production of such adhesives. In particular, the adhesives have reduced content of monomeric diisocyanates or no monomeric diisocyanate content.
Abstract:
Disclosed are a halogen-free fire-retardant polyamide composition, and a preparation method and application thereof. The halogen-free fire-retardant polyamide composition is prepared from 35 to 71.5% of a semi-aromatic polyamide, 10 to 35% of a fire retardant and 0 to 50% of an inorganic reinforcing filler, the terminal amino group content of the semi-aromatic polyamide being 80 to 150 mol/t. The halogen-free fire-retardant polyamide composition of the present invention has good heat stability and releases only a small amount of gas in production; mold dirt is not easily formed, and the halogen-free fire-retardant polyamide composition can be produced continuously.
Abstract:
The present invention relates to a composition comprising polystyrene or modified-polystyrene or a mixture thereof, said polystyrene or modified-polystyrene or mixture thereof further comprising carbon nanotubes; wherein the composition comprises a polyolefin; and wherein the composition comprises at most 1.90% by weight of carbon nanotubes, based on the total weight of the composition. The present invention also relates to a method for the preparation of the composition, wherein the carbon nanotubes are provided in polyolefin or styrenic copolymer masterbatch.
Abstract:
The present invention relates to a lead-free, non-toxic and arc resistant composite material having a thermosetting polymer, at least one heavy particulate filler, at least one light particulate filler and, optionally, at least one arc resistant filler. The composite material may be utilized in manufacturing articles used in radiation shielding and other applications where arc resistant and dielectric strength are desired.
Abstract:
A blow-molded container comprises a layer having a thermoplastic material and an additive, wherein the thermoplastic material and the additive have a Solubility Parameter difference of from about 0.5 cal1/2 cm−3/2 to about 20 cal1/2 cm−3/2, and have a Refractive Index difference of from about 0.1 to about 1.5. Such a container has a desirable glossy appearance.
Abstract:
Disclosed are methods, compositions and systems pertaining to polymer coatings that entrap enzymes, specifically enzymes capable of reducing carboxylic acids.
Abstract:
A polymeric film assembly for application to at least one surface of an article comprises a polymeric film comprising an exterior surface, wherein the polymeric film comprises at least one clay in an anti-smudge effective amount, and wherein the polymeric film is essentially free of low surface energy components. A method for application of a polymeric film to at least one surface of an electronic device is also disclosed.
Abstract:
The invention provides a biaxially-oriented polyester film that comprises a biaxially oriented polyethylene terephthalate film and contains 9000 ppm or less of ethylene terephthalate cyclic trimer, has a molten specific resistance of within 1.0×108Ω·cm, and at least one surface of the film has a surface resistivity of 13 log Ω or less under a relative humidity of 65%. The invention also provides a wrap-around label for a container produced from the film.
