Oriented film comprising poly(ethylene-2,5-furandicarboxylate)
An oriented film including poly(ethylene-2,5-furandicarboxylate) is produced in a process by preparing a sheet from a poly(ethylene-2,5-furandicarboxylate) resin by heat processing, which sheet has a thickness of at most 2.5 mm; allowing the sheet to cool; and stretching the cooled sheet in at least one direction with a stretch ratio of at least 4/1 at a temperature in the range of 90 to 130° C., yielding an oriented film. The oriented film has a thickness of 1 to 400 μm and a tensile strength at break of at least 100 MPa.
METHOD FOR PRODUCING PREPREG AND METHOD FOR MOLDING COMPOSITE MATERIAL
A method for producing a prepreg in which a reinforcing fiber base material is impregnated with a resin to produce a prepreg, wherein said method comprises: a step for preparing a first resin, which is the resin containing a filler, and a second resin, which is the resin not containing a filler; a step for arranging the second resin adjacent to the reinforcing fiber base material; a step for arranging the first resin adjacent to the reinforcing fiber base material and/or the second resin; and a step for impregnating the reinforcing fiber base material with the resin of the first resin and the second resin.
POLYSACCHARIDE COATINGS WITH OXYGEN BARRIER PROPERTIES
Disclosed herein are coated articles comprising a substrate having at least one surface, and a coating composition disposed in a substantially continuous layer on at least one surface of the substrate, wherein the coating composition is present in an amount sufficient to increase the oxygen barrier property of the substrate, and the coating composition comprises a polysaccharide derivative. The polysaccharide derivative can comprise a poly alpha-1,3-glucan ether compound, such as a quaternary ammonium alpha-1,3-glucan ether. Also disclosed is packaging comprising the coated article.
METHOD FOR MANUFACTURING HIGH-TEMPERATURE STRUCTURAL MATERIAL AND PRECURSOR
Disclosed are a method for manufacturing a high-temperature structural material and a precursor. The method includes following operations: providing a precursor, wherein the precursor is made of a polymer or the polymer and a high-temperature material; processing the precursor into a precursor object with a preset shape; and converting the processed precursor object into a high-temperature material object through a preset processing method.
Plastics coloring using cottonseed oil-based liquid color compositions
A method of fabricating plastic products having a preselected color, comprising preparing a dispersion of pigment of the preselected color in cottonseed oil; supplying a preselected plastic resin for the product to be fabricated to a process machine having a rotating screw; furnishing the dispersion to the process machine at a position adjacent to threaded portion of the rotating screw; and blending the dispersion and the resin by rotating the screw.
Articles and Methods for Manufacture of Nanostructure Reinforced Composites
An article includes a hybrid nanocomposite product, which includes a nanostructure array and a resin matrix contained among and/or around the nanostructure array. The array/matrix is placed in between layers of dry or resin-infused fiber composite to permit formation of a composite structure. The nanostructure array and/or the resin matrix may be disposed in an abutting relationship with other layers of a composite. The array/matrix can provide reinforcement of the composite in the z-direction. Transfer of resin into dry fiber forms may be provided when the array/matrix acts as a resin transfer medium. Nanostructure arrays with a resin matrix can be prepared to form a resin film product. Methods are presented for infusing composites via resin-transfer molding (RTM), vacuum-assisted resin transfer molding (VARTM), resin film infusion (RFI), or injection molding wherein a resin matrix film substantially maintains alignment and position of the nanostructure array during the infusion process.
Algae-blended thermoplastic compositions
An algae-based thermoplastic composition is provided that includes a protein-rich algae biomass selected from either microalgae, macroalgae or combinations thereof. The protein content is greater than or equal to 15% by weight of the algae biomass and the algae biomass is dried to a moisture content of less than or equal to 15% by weight and having a particle d99 of up to 200 microns. The dried algae biomass is at least 5% by weight of the thermoplastic composition. The composition includes a biodegradable resin configured to exhibit rheological properties suitable for blending with algae including a melting temperature less than 250° C. and a melt flow rate in excess of 0.01 g/10 min.
DEPOLYMERIZED LIGNOSULFONATE AND LIGNIN AS EXTENDER FOR PHENOLIC RESIN
A resin composition for impregnating paper products used in manufacture of high-pressure decorative laminates includes a resin and lignin derivatives.
Multilayer articles via wet-on-wet processing
Wet-on-wet coating processes are provided to produce multilayer articles. First and second coating materials are sequentially applied on to a structured substrate surface to form a skin layer directly over the structured substrate surface and a bulk layer over the skin layer. The conformability of the skin layer can be adjusted to provide desired surface and bulk properties.
COMPOSITION AND METHOD FOR MICROBIAL CONTROL FOR USE WITH POLYMERS
A composition having an additive or component having an antimicrobial or a preservative property, and 3-phenylpropanol or a member of the phenylpropanoid family is provided. A composition having a polymer, an organic acid, and 3-phenylpropanol or a member of the phenylpropanoid family is provided as well as a method(s) of using.
