Molded foam articles are provided. The molded foam articles are formed from polylactic acid and are capable of a number of post-processing or secondary uses. Forming the molded foam articles from polylactic acid advantageously extend the life of the molded bead foam article by permitting users to cut, heat, adhere, modify, and repurpose the molded foam articles.

Described herein is a process for preparing a foam (FA) with a Poisson's ratio in the range of from −0.5 to 0.3, the method including the steps of providing a foam (F1) with a flow resistance in the range of from 3000 to 8000 Pas/m, determined according to DIN EN 29053, and subjecting the foam (F1) to thermoforming including triaxial compression, wherein the foam (F1) is not reticulated prior to step (ii). Also described herein is the foam obtained or obtainable according to the process and the use of the foam as, for example, an energy absorbing device, preferably in protective gear, furniture, cushions, in cleaning devices with improved rinse-out behavior, in shoe soles, or as sealing, insulating or anchorage providing material for example used in earphones, ear plugs or dowels, or as acoustic material.

The present invention relates to a food container with a reduced amount of elution of hazardous substances. As the food container according to the present invention has a structure in which a foamed layer and a PETG resin layer are laminated, compressive strength is improved and moldability is excellent, so that the food container may be provided in various sizes and shapes. Moreover, the present invention has a harmless effect to a human body due to a remarkably low amount of elution of hazardous substances.

The present disclosure provides a recombinant collagen and a recombinant collagen sponge material. The recombinant collagen comprises: (a) a protein composed of the amino acid sequence represented by SEQ ID NO: 2; and/or (b) a protein which has the same function as (a) and is derived from (a) by substitution, deletion and/or addition of one or more amino acids in SEQ ID NO:2. The recombinant collagen sponge material is obtained by sequential physical cross-linking and chemical cross-linking of the recombinant collagen. The recombinant collagen sponge material according to the present disclosure is capable of hemostasis, wound surface repair, moisture absorption and platelet aggregation, and has high moisture absorption, a significant hemostatic effect and good biocompatibility, assuming great clinical significance in the field of surgery.

Methods of making blended, isoporous, asymmetric (graded) films (e.g. ultrafiltration membranes) comprising two or more chemically distinct block copolymers and blended, isoporous, asymmetric (graded) films (e.g. ultrafiltration membranes) comprising two or more chemically distinct block copolymers. The generation of blended membranes by mixing two chemically distinct block copolymers in the casting solution demonstrates a pathway to advanced asymmetric block copolymer derived films, which can be used as ultrafiltration membranes, in which different pore surface chemistries and associated functionalities can be integrated into a single membrane via standard membrane fabrication, i.e. without requiring laborious post-fabrication modification steps. The block copolymers may be diblock, triblock and/or multiblock mixes and some block copolymers in the mix may be functionally modified. Triblock copolymers comprising a reactive group (e.g., sulfhydryl group) terminated block and films comprising the triblock copolymers.

Implantable devices for orthopedic, including spine and other uses are formed of porous reinforced polymer scaffolds. Scaffolds include a thermoplastic polymer forming a porous matrix that has continuously interconnected pores. The porosity and the size of the pores within the scaffold are selectively formed during synthesis of the composite material, and the composite material includes a plurality of reinforcement particles integrally formed within and embedded in the matrix and exposed on the pore surfaces. The reinforcement particles provide one or more of reinforcement, bioactivity, or bioresorption.
