The present invention relates to an Eco-friendly foam, and more particularly, to an Eco-friendly foam that exhibits excellent foamability, excellent thermal insulation performance, a remarkably small amount of harmful gas emission, and excellent dimensional stability and elasticity.

A composite material is formed by combining an expandable polymer having a charge with another polymer having an opposite charge to produce. In particular, the composite material can be prepared by combining the polymers with a medium such as and water, and expanding the mixture using a treatment that expands the mixture to produce, for example, insoluble porous foam-like composites.

A method and a mineral wool product include a multiple of lamellae, such as a sandwich panel core. The product includes a plurality of lamellae cut from a mineral wool web, and bonded together by applying an adhesive on the surfaces of two adjacent lamellae to form a web-like product, wherein the adhesive comprises at least one hydrocolloid.

Described is a method for producing a thermoplastic starch, wherein a mixture is extruded comprising starch and a polyol, preferably selected from the group comprising polyethylene glycol, monosaccharides, sugar alcohols and mixtures thereof, in a quantity of 0 to 9.9 wt. % of the mixture, and an epoxide, selected from the group comprising epoxidised vegetable oils, and mixtures thereof, in a quantity of 0.1 to 6 wt. % of the mixture, the mixture further containing an acid, preferably a carboxylic acid selected from the group consisting of citric acid, malic acid or tartaric acid, in a quantity of 0.1 to 1 wt. % of the mixture, and being devoid of polyester urethane. The invention also describes a thermoplastic starch produced in this way, a compound produced with the aid of the thermoplastic starch, and a film produced from such a compound or an injection-moulded item produced from such a compound.

Disclosed herein compositions of polysaccharides chemically cross-linked by aromatic dialdehydes. The compositions may be in form of polymeric sheets for a variety of applications. Disclosed also nano-sized particles comprising the polysaccharide chemically cross-linked by aromatic dialdehydes. The nano-sized particles may further comprise lipids and surfactants. Intranasal delivery of the nano-sized particles enables delivery of biologically active agents into the brain. Topical and transdermal delivery of the nano-sized particles enables delivery of biologically active agents for treatment of systemic or dermatological disorders. Methods of manufacturing and uses of the compositions are also disclosed.

The present invention provides a composition comprising at least one organic component having particles between 1 and 4 mm, and a cured thermoset polymer, and wherein a w/w ratio of the organic component to the thermoset polymer within the composition is between 4:1 and 10:1. Furthermore, provided herein are articles in a form of planting pots comprising the composition of the invention. The invention also provides a method for manufacturing of planting pots.

A foam comprising starch and urea is described. A composition of the foam, by weight percent, includes a starch weight percent representative of the starch included in the foam and a urea weight percent representative of the urea included in the foam. The starch weight percent is greater than the urea weight percent.

A bio-based UV-curable 3D printed resin includes the following components by weight percentage: 19-78% of biodegradable starch resin polymer, 1-9% of radical initiator, 0.2-4% of adjuvant, 13-62% of reactive diluent and 2-8% hydroxyethyl starch. The preparation method thereof comprises the following steps of: mixing the above components by component proportion, ultrasonically washing the mixture for 10-20 min by an ultrasonic cleaner under a water temperature of 50° C., and then mixing the same in a homogenizer homogeneously to obtain the bio-based UV-curable 3D printed resin. The renewable resources are adopted and the environmental pollution and energy consumption are reduced, which is of bio-safety. Moreover, the hydroxyethyl starch has a high molecular compound generated by hydroxyethylation of glucose ring of amylose, resulting in various benefits. The 3D printed resin obtained has excellent performance and low skin irritation value.

Thermoplastic starch materials and methods of making the same are provided. The methods involve mixing a starch material, plasticizer and water in a low-shear mixer under conditions that will result in substantial gelatinization of the starch material. The melt formed within the mixer is discharged into an extruder for final processing. The methods prevent degradation of the starch material thereby resulting in the formation of a thermoplastic starch material having high strength, due at least in part to the preservation of the molecular weight characteristics of the starch, and improved elasticity due the ability to use higher water contents than conventional processes.

The invention is directed to a method of preparing a blend comprising a polysaccharide and a water soluble or dispersible ingredient. More in particular, the invention relates to the preparation of such blend using a filter centrifuge. The method of the invention comprises a. feeding a polysaccharide slurry to a filter centrifuge via a first inlet; b. rotating the filter centrifuge at a first centrifuge speed to provide a polysaccharide cake; c. feeding a sprayable ingredient to the filter centrifuge via a second inlet; and d. spraying the sprayable ingredient onto the polysaccharide cake while rotating the filter centrifuge at a second centrifuge speed to produce a blend of the polysaccharide and the ingredient.
