A filter cartridge includes a radio frequency identification, RFID, tag positioned on a casing. A compressed cellulose foam is positioned over the RFID tag on the casing. An impermeable material is positioned over the cellulose foam on the casing at an outer surface of the casing. The impermeable material defines a passage that extends through the impermeable material to the cellulose team. The passage is configured such that water is flowable through the passage to the cellulose foam. The compressed cellulose foam is configured for wicking the water from the passage to the RFID tag.

The present application includes a foam product having a foam member with one or more cavities below a surface of the foam member. A dry fill material is located within the one or more cavities to the level of the surface of the foam member. A coating material is applied to the combined foam member and dry fill material. The coating material is permitted to pass around the dry fill material and fill the one or more cavities. The coating material infusing to the foam member within throughout the one or more cavities.

The present relates to flame-retardant expandable polymers and to polymer foams and to the use thereof. These flame-retardant expandable polymers and polymer foams can be contained in one or several pressurized containers. According to the present, at least one of the following phosphorus compounds is used as a flame retardant: phosphorus compound according to formula (Ia): (Ia) 10-hydroxy-9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO-OH); or the salts thereof according to formula (Ib): (Ib) (DOPO-OR); or the ring-opened hydrolysates thereof according to formula (Ic): (ilc).

The present disclosure discloses a method for preparing a polyurethane foam using an extract of cotton spinning black liquor, including the following steps: step (1): extracting biomass in cotton spinning black liquor by acid precipitation to obtain the extract of cotton spinning black liquor; step (2): pretreating the extract of cotton spinning black liquor, and uniformly mixing the pretreated extract of cotton spinning black liquor with a polyether polyol to obtain a mixed raw material; and step (3): preparing the polyurethane foam from the mixed raw material, dibutyltin dilaurate, distilled water, a foam stabilizer, aluminum hypophosphite and an isocyanate by one-step foaming. The present disclosure can solve the problems of high treatment cost and low utilization rate of the existing cotton spinning black liquor.

A nanoporous aerogel comprising an acid-catalyzed, oxidatively aromatized PBO polymer. The nanoporous aerogel includes a benzoxazine moiety containing polybenzoxazine polymer with up-to six sites of cross-linking per unit is the product of the high yield, room temperature, and acid catalyzed synthesis method, as provided for herein. A method of producing the aerogel is providing that results in robust monoliths, oxidative aromatization, and conversion to nanoporous carbons for the provided aerogels. The PBO polymer may be co-generated as an interpenetrating network with a metal oxide network, wherein the PBO network serves as both a reactive template and as a sacrificial scaffold in the synthesis of the pure, nanoporous, monolithic metal aerogels, in an energy efficient method. ##STR00001##

An object of the present invention is to provide a resin composition that can produce a foam molded body having a beautiful appearance while exhibiting excellent mechanical properties. The above object is achieved by a resin composition for producing foam particles, the resin composition comprising a base resin containing a polycarbonate resin having a glass transition temperature of 140 to 155 C. and an amorphous polyester resin having a glass transition temperature of 100 to 130 C., and the amorphous polyester containing a unit derived from a cyclic diol.

A reinforcing sheet including one or more layers of a reinforcing material, and a thermosetting adhesive associated with the reinforcing material, wherein the thermosetting adhesive includes a curing agent, and an epoxy-modified dimerized fatty acid combined with an epoxy terminated polyurethane interpenetrating network.

The present invention relates to a complex and a material containing the same for oil-water separation. The preparation process of the complex is simple. The complex shows lipophilicity, superhydrophobicity, and super water-repellency since a zinc oxide particle layer, in which zinc oxide particles are agglomerated in a micro-nano structure, and a super-hydrophobic coating layer having low surface energy are sequentially formed on a surface of a polymer matrix having a cavernous porous structure, and thus the complex has high oil-water separation efficiency and high durability. When a magnetic particle layer exhibiting magnetism is provided between the zinc oxide particle layer and the super-hydrophobic coating layer, the positional control and collection of the complex is easy, and thus the complex can be helpfully used as a material for oil absorption type oil-water separation, which is used in large-scale oil-water separation, such as the removal of oil spilled into the ocean.

An expanded bead has a foamed layer made of a polypropylene-based resin and a specific shape including one or more defective portions. The polypropylene-based resin constituting the foamed layer contains a polypropylene-based resin (A) having a melting point of 135 C. to 150 C. and a flexural modulus of less than 1000 MPa, and a polypropylene-based resin (B) having a melting point of 145 C. to 160 C. and a flexural modulus of 1000 MPa or more. The mass ratio between the resin (A) and the resin (B) in the polypropylene-based resin is represented by resin (A):resin (B)=65:35 to 35:65.
