Abstract:
The present invention relates to a multistage process including at least two steps for making a heat and oil resistant preroxide-cured thermoplastic vulcanizates (TPV) based on hydrogenated carboxiated nitrile butadiene rubber (HXNBR) and at least one polyamide. TPV's according to the present invention have improved properties and morphology over known TPV's prepared in single-stage processes.
Abstract:
The present invention relates to a polymer compound containing at least one carboxylated nitrile rubber polymer, that is optionally hydrogenated, at least one organo functional silane compound having at least one epoxy, amine, isocyanate, or any other functional group capable of forming a derivative of a carboxyl group, at least one silane group, and at least one filler, a method of inducing curing in a compound containing at least one carboxylated nitrile rubber polymer, that is optionally hydrogenated, by addition of at least one organo functional silane compound having at least one epoxy, amine, isocyanate, or any other functional group capable of forming a derivative of a carboxyl group, at least one silane group, and at least one filler and subsequent curing.
Abstract:
The present invention relates to an elastomeric composition containing a nitrile rubber, preferably hydrogenated, and a filler. Compositions according to the present invention have high filler levels, excellent processability, and very good resistance to aggressive fluids and fuels compared to known HNBR compositions.
Abstract:
An elastomeric composition containing a rubber polymer, an acid acceptor, and a silane-modified needle-like/acircular mineral additive. Compositions according to the present invention have superior heat resistance, compression set resistance, and improved processability (lower compound Mooney) compared to known rubber compositions.
Abstract:
The present invention relates to thermoplastic vulcanizates (TPVs) based on low Mooney, optionally hydrogenated nitrile butadiene rubber and polyamides. The present invention also relates to TPVs based on low Mooney, optionally, hydrogenated nitrile terpolymers and polyamides. TPVs prepared according to the present invention have improved morphology, smaller rubber particle size, and improved processability compared to TPVs containing non-low Mooney, optionally hydrogenated nitrile butadiene rubber.
Abstract:
The present invention relates to an elastomer rubber composition containing a carboxylated rubber polymer and a fluorinated additive. The present invention is also directed to an elastomer composition containing a hydrogenated carboxylated nitrile rubber and a fluorinated additive.
