Absorbent aliphatic polyurethane foam product
The present invention relates to foam. In particular, the present invention relates to profiled foams and processes for profiling absorbent foam products. More particularly, the present invention relates to processes for producing a profiled absorbent polyurethane foam product, comprising the steps of foaming, curing, profiling and drying, wherein profiling occurs before drying; and absorbent aliphatic polyurethane foam products having at least one profiled surface.
Crosslinked polyolefin separator and manufacturing method thereof
A method for manufacturing a crosslinked polyolefin separator and a separator are provided. The method includes putting a polyolefin and a polyolefin elastomer into an extruder first, and putting an alkoxy silane containing a carbon-carbon double bond functional group, an initiator and a crosslinking catalyst to form the separator. The crosslinked polyolefin separator has high meltdown temperature and low shutdown temperature.
PREPREG, PREFORM, FIBER-REINFORCED COMPOSITE MATERIAL, AND METHOD FOR PRODUCING SAID PREPREG, SAID PREFORM OR SAID FIBER-REINFORCED COMPOSITE MATERIAL
An object of the present invention is to provide a fiber-reinforced composite material achieving both lightweight properties and mechanical properties, a laminate thereof, and a prepreg capable of easily molding a sandwich structure thereof. The present invention is a prepreg comprising a reinforced fiber substrate (B) impregnated with a resin (A), wherein the reinforced fiber substrate (B) exists in a folded state having a plurality of folds with a fold angle of 0° or more and less than 90° in the prepreg.
PREPREG, PREPARATION METHOD THEREOF AND FIBER REINFORCED COMPOSITE MATERIAL PREPARED THEREFROM
The present disclosure relates to a prepreg, a preparation method thereof and a fiber-reinforced composite material prepared therefrom. The preparation method of a prepreg may include an aramid fiber base material with improved wettability to resin, can increase a thickness reduction rate during molding of the prepreg, has an appropriate resin content, and can provide a prepreg suitable for molding by an out-of-autoclave process. In addition, the prepreg may provide a fiber-reinforced composite material that exhibits a thin thickness and a high resin content even by an out-of-autoclave process, and shows high strength and low moisture absorption
METHOD FOR PRODUCING A 3D-PRINTED TISSUE SUBSTITUTE
A method for producing a 3D-printed tissue substitute is disclosed, utilizing a 3D printing device including a tank including a yield stress fluid in which the material is printed, the printing material delivered by the cartridge includes polyvinyl alcohol and gelatin, the method including a step following which, after printing the material in the yield stress fluid, a printed intermediate device is solidified in the yield stress fluid by lowering the temperature of the tank. The intermediate device is removed from the tank, rinsed and dried in order to obtain the tissue substitute.
Multiphenylethynyl-Containing and Lightly Crosslinked Polyimides Capable of Memorizing Shapes and Augmenting Thermomechanical Stability
The invention generally relates to shape memory films that are tri-functionally crosslinked and that comprise multiple, non-terminal, phenylethynyl moieties. In addition, the present invention relates methods of fabricating such films. Due to the improved properties of such SMPs, the SMP designer can program in to the SMP thermomechanical property enhancements that make the SMP suitable, among other things, for advanced sensors, high temperature actuators, responder matrix materials and heat responsive packaging.
METHOD FOR PRODUCING A THREE-DIMENSIONAL PRINTED ARTICLE
The present invention relates to a method for producing a three-dimensional (3D) printed article with a photocurable silicone composition involving a silicone containing as end-group specific (meth)acrylate groups.
METHOD OF MANUFACTURING VENTILATION SHEET FOR VEHICLE
Disclose are is method of manufacturing a ventilation sheet for a vehicle. The ventilation sheet for a vehicle is manufactured by performing anti-fouling finishing treatment using an anti-fouling coating agent including an anti-fouling composition. The anti-fouling properties can be improved to prevent the sheet from being fouled, and flame-retardant treatment is performed through a flame-retardant aqueous solution including flame-retardant PET fiber and flame retardant in bath so that the deterioration of flame retardancy caused by the improved anti-fouling properties can be prevented through the flame-retardant treatment while ventilation properties are maintained.
COMPOSITE TUBE AND METHOD OF MAKING
A composite tube includes a first layer including a cross-linked polyolefin elastomer, wherein the first layer is configured for fluid contact; and a second layer adjacent to the first layer, the second layer including an elastomer.
Thermally expandable compositions comprising urea derivatives
The present application relates to a thermally expandable composition containing at least one peroxide cross-linking polymer, at least one peroxide and at least one endothermic, chemical blowing agent, the blowing agent comprising at least one solid, optionally functionalized, polycarboxylic acid or the salt thereof and at least one urea derivative according to the formula (I) as defined herein; as well as shaped bodies containing the composition and to a method for sealing and filling voids in components, for strengthening or reinforcing components, in particular hollow components, and for bonding mobile components using shaped bodies of this type.
