The present invention relates to a kit comprising a mould (1; 101; 201) for kids and a powder water-sensitive mixture (M) for making a bijou through the mould, wherein the mould (1; 101; 201) comprises at least one body (2; 102) having a lower face, an opposing upper face (3) and a side wall (4) comprised between the lower face and the upper face (3), and at least one cavity (5) opened on the upper face (3) and equipped with a bottom (6), wherein the at least one body (2; 102) is of a flexible and/or deformable material, and wherein the mixture comprises polyvinyl alcohol, guar gum and ethylene vinyl acetate.
摘要:
The invention is a flash separator for separating an olefin copolymer mixture from volatile gases. The flash separator can be used with a solution or high pressure process. The object is to increase the mass transfer of volatile gases from the polymer melt.
摘要:
A cable comprising a covering having two or more different sheath layers, with the covering providing superior chemical and weathering resistance, and excellent surface feel. In a preferred embodiment, the outermost sheath layer of the covering is a thermoplastic elastomer essentially free of a flame retardant material, yet the covering achieves desirable flame retardant performance due to the presence of an inner sheath layer comprising a thermoplastic elastomer and a flame retardant, preferably halogen- free flame retardant. The outermost sheath layer also exhibits sought-after surface qualities. Methods for producing the coverings and flame retardant cables are disclosed.

摘要:
A flame retardant compound is provided. The flame retardant compound includes a polymer base resin, a carbonific host compound, and a guest compound including at least one atom of a transition metal. The carbonific host compound and the guest compound form a host-guest complex, and the host-guest complex acts to inhibit at least one of smoke release and smoke formation when exposed to heat. The host-guest complex is distributed within the polymer base resin. An intumescent flame retardant compound is also provided. The intumescent flame retardant compound includes a base resin, an acid donor, a spumific agent, a cyclodextrin host compound, and a guest compound including at least one atom of molybdenum. The cyclodextrin host compound and the guest compound form a host-guest complex. The acid donor, carbonific host compound, and spumific agent react when exposed to a temperature above 280 °C to form a foam.
摘要:
The invention relates to an adhesive composition comprising: - at least one hydrocarbon resin in an amount of at most 40% by weight with respect to the total weight of the composition; - at least one polyolefin derived from the polymerization of ethylene and/or propylene with metallocene catalysis having a density in the range from 0.8 to 0.9 g/cm 3 , and; - ethylene vinyl acetate (EVA) copolymer in an amount of at most 15% by weight with respect to the weight of the composition. Such adhesive composition allows preparing a ready-to-use adhesive product, applicable by rubbing and which does not require packaging during use.
摘要:
A medical tube that contains a polymer composition that is generally flexible and biocompatible is provided. The polymer composition contains at least one ethylene vinyl acetate polymer and at least one viscoelastic additive. By selectively controlling specific aspects of the ethylene vinyl acetate polymer (e.g., vinyl acetate content, melt flow index, density, etc.), the viscoelastic additive, and the manner in which they are blended, the resulting composition can exhibit a reduced tendency to kink when formed into the medical tube.
摘要:
The present invention relates to a hot melt composition, which is suitable as a damping, preferably a sound deadening, composition comprising i) at least one poly-α-olefin; ii) at least one elastomeric styrene based copolymer; iii) at least one tackifier; iv) at least one macrocycle; and optionally v) at least one additive, preferably selected from fillers; stabilizers; colorants; pigments; waxes; thermoplastic compounds having a melt index of 600 to 5000 at 190℃/2.16 kg (ASTM D1238) selected from ethylene vinyl acetate (EVA), ethylene acrylic acid (EAA), alkyl acrylates, alkyl methylacrylates (EMA), ethylene 2-ethyl hexyl acrylate (EEHA) polymers or combinations thereof; moisture scavengers; or combinations thereof. Furthermore, the present invention relates to a dampening, preferably a sound deadening, article comprising the hot melt composition of the present invention and the use of the hot melt composition of the present invention in dampening, preferably sound deadening.
摘要:
Techniques are disclosed for producing multilayered composites of adhesive nanofiber composites. Specifically, one or more sheets of highly aligned nanofibers are partially embedded in an adhesive such that at least a portion of the nanofiber sheet is free from adhesive and is available to conduct current with adjacent electrical features. In some example embodiments, the adhesive nanofiber composites are metallized with a conductive metal and in these and other embodiments, the adhesive nanofiber composites may also be stretchable.
摘要:
The present invention relates to aqueous polyurethane dispersions prepared with no catalyst or very low loading of organic catalyst that can be used as cold sealable adhesives, are surfactant and solvent free and have low VOC emissions, are environmentally friendly, and provide for homogeneous and aging-resistant adhesives that can be used for cosmetic, pharmaceutical and food packaging applications. Also encompassed are processes for their production, compositions containing them and their use as adhesives.
