Cellulose acetate composition for thermoforming, molded article, and method for producing cellulose acetate composition for thermoforming
An object of the present invention is to provide a cellulose acetate composition for thermoforming with excellent biodegradability and excellent thermoformability. A cellulose acetate composition for thermoforming containing a cellulose acetate and a glycerin ester-based plasticizer, wherein the cellulose acetate has a degree of acetyl substitution of 1.4 or greater and 2.0 or less, a compositional distribution index (CDI) of 4.0 or less, and a total sulfur content of 15 mg/kg or greater and less than 150 mg/kg.
VEHICLE SEAT CONTAINING FIBER COMPOSITE MATERIAL AND EXPANDED THERMOPLASTICS
The invention relates to a seat for a vehicle, preferably for a land craft, a watercraft, and/or an aircraft, comprising at least one multilayer structural component (1) with at least one first (6) and at least one second ply (5) of a composite material, in each case containing fibers which are integrated into a thermoplastic, and with a layer (7) which is arranged between said plies and is made of at least one foamed thermoplastic; to a method for producing same, said method having at least the following steps (A): providing at least one first and at least one second ply of a composite material, in each case containing fibers which are integrated into a thermoplastic, (B) thermoforming the first ply of composite material into a lower seat shell, (C) thermoforming the second ply of composite material into an upper seat shell, (D) arranging the lower seat shell and the upper seat shell in a tool, such that a gap is formed between the two seat shells, (E) introducing foamed particles made of a thermoplastic into the gap, and (F) pressing the two seats shells and the foamed particles in order to obtain the seat; and to the use of the seat in a vehicle, preferably in a land craft, a watercraft, and/or an aircraft.
BIODEGRADABLE RESIN COMPOSITION AND MOLDED ARTICLE
Provided are an inorganic substance powder-blended biodegradable resin composition exhibiting excellent processability, sufficient mechanical strength and excellent flexibility as a molded product, and having economic advantage, as well as having excellent degradability under a natural environment and a molded product formed by using the composition. Provided is a molded product molded by using an inorganic substance powder-containing biodegradable resin composition including: a biodegradable resin and an inorganic substance powder in a range by mass of 10:90 to 70:30, in which the biodegradable resin is a multicomponent hydroxyalkanoic acid copolymer comprising lactic acid and other hydroxyalkanoic acid and the inorganic substance powder is heavy calcium carbonate.
Knit textiles and uppers, and processes for making the same
Articles of wear having one or more textiles that include a low processing temperature polymeric composition and a high processing temperature polymeric composition, and methods of manufacturing the same are disclosed. The low processing temperature polymeric composition and the high processing temperature polymeric composition can be selectively incorporated into a textile to provide one or more structural properties and/or other advantageous properties to the article. The textile can be thermoformed to impart such structural and/or other advantageous properties to the article of wear. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
RECYCLABLE ABRASION RESISTANT DUNNAGE TRAY
A chaff resistant and economically recyclable dunnage tray is disclosed. In one aspect, the dunnage tray includes a base portion formed from a first material and a top portion formed from a second material. The top portion is secured to the base portion, and defines at least one cavity or recess for supporting a machine component. The first and second materials are high density polyethylene (HDPE) materials with the second material including polyethylene elastomers, or plastomers. In one example, the dunnage tray is formed by thermoforming a co-extruded sheet including a first layer corresponding to the bottom structural portion and a second layer corresponding to the elastomer or plastomer portion. In one example, the dunnage tray is formed by thermoforming an extruded sheet to form the base portion and by attaching separately formed top portions with polyethylene elastomers, or plastomers to the thermoformed base portion. This invention provides solutions to chaffing or chipping of polyethylene dunnage trays, control of coefficient of friction and softness to minimize parts from sliding/abrading dunnage surfaces, and eliminates requirements for disassembly of dunnage trays and separation of materials prior to recycling.
Stress Relaxation Resistant Orthodontic Appliances
Orthodontic appliances formed from a material that includes an interpenetrating polymer network or semi-interpenetrating polymer network material to prevent or reduce stress relaxation of the material during use by a patient. Methods for forming orthodontic appliances from a material that includes from an interpenetrating polymer network or semi-interpenetrating polymer network material to prevent or reduce stress relaxation of the material during use by a patient.
SYSTEMS AND METHODS FOR SINGLE-USE COMPOSTABLE CONTAINERS
A compostable single-use container generally includes a substantially planar lid component and a tray component. The lid component has a top surface and a bottom surface. The tray component has a generally planar top surface adhesively bonded to the bottom surface of the lid component with a sustainable adhesive, and a chamber configured to store an object. The tray component is thermoformed fiber comprising at least one of recycled cardboard, hemp straw, and cannabis straw. The lid portion comprises at least one of a natural-fiber card stock and a compostable sticker.
Process for producing composite material parts by impregnating a specific preform
A method for producing a composite material. The method includes the steps of producing an initial dry preform, formed from unidirectional continuous dry fibers, applying non-woven filaments to a first main face of the dry preform, and needling the filaments with a needling device. The needling device includes a plurality of needles, each provided with at least one notch, so that filaments are driven by the needles and arranged in a direction substantially perpendicular to the continuous fibers of the dry perform. The method includes the further step of impregnating the dry preform with an impregnation polymer, the impregnation polymer constituting the matrix of the composite material part.
