The present invention provides a flame-retardant styrene polymer composition comprising an organic bromine compound, zinc stearate and calcium stearate, the use for preparing styrene polymer films or foams and a process for recycling of styrene polymer-containing scrap.

What is described is a composition for production of rigid polyurethane foam, comprising at least one isocyanate component, a polyol component, optionally a foam stabilizer, optionally blowing agent, wherein the composition contains at least one catalyst that catalyses the formation of a urethane or isocyanurate bond, wherein the catalyst comprises salts of amino acid derivatives.

Provided are rapidly cross-linkable silicone foam compositions, kits, and methods for filling implanted medical devices in situ or in vivo, the implanted medical devices, including for example, body implants and tissue expanders, the compositions including a platinum divinyl disiloxane complex; a low viscosity vinyl terminated polydimethylsiloxane; a low viscosity hydride terminated polydimethylsiloxane; a silicone cross-linker; and a gas and/or gas-filled microcapsules, where the rapidly cross-linkable silicone foam composition has a viscosity of ≤150 cPs for ≥1 min. post-preparation and ≤300 cPs≤5 min. post-preparation, at ambient temperature.

The thermoplastic elastomer composition contains a thermoplastic elastomer and a pigment.

The thermoplastic elastomer composition contains a thermoplastic elastomer and a pigment.

Embodiments of the present disclosure are foam formulations. As an example, foam formulation can include a polyol composition having an amine-imitated polyol that is from 10 percent to 20 percent of a total weight of the polyol composition and an additional polyol that is from 80 percent to 90 percent of the total weight of the polyol composition, a polyisocyanate, a blowing catalyst, and a gel catalyst, where a combination of the blowing catalyst and the gel catalyst is from 0.5 percent to 1.5 percent the total weight of the polyol composition and where the blowing catalyst is from 50 percent to 100 percent of a total weight of the blowing catalyst and the gel catalyst.

A foaming assistant material and a foam-molding method, which can achieve the functions of a nucleating agent, a dispersant, and the like sufficiently so that the cells can have smaller diameter, the mixing of foreign substances is prevented, and so on, and can produce the high-quality foam-molded article, are provided. The foaming assistant material is kneaded together with a raw material pellet and the mixture is subjected to the foam molding. The foaming assistant material is a pellet obtained by adding inorganic particles, a chemical foaming agent, and a dispersant to a dilution resin. An antioxidant may be added further to the dilution resin. In the foam-molding method, inorganic particles, a chemical foaming agent, a dispersant, and an antioxidant are added to a raw material resin at the same time in a state that the inorganic particles, the chemical foaming agent, the dispersant, and the antioxidant are mixed in advance.

The present invention provides a master batch composition for environmentally degrading conventional plastics including a carrier resin, at least one oxidative degradant, at least one nature biodegradable degradant and at least one foaming agent. The present invention also provides a plastic product which is environmentally degradable at a very low cost versus conventional bio-sourced plastics, and has broad applications for single-use disposable applications or for short-lived products that are discarded within two years of manufacture.

The present invention relates to a multilayer floor decorative material comprising a foam layer, wherein the foam layer comprises a polyvinyl chloride resin, a plasticizer, a filler, a heat stabilizer and a foam stabilizer, the foam layer is formed by a mechanical foaming method, the heat stabilizer comprises barium stearate and zinc stearate, and the foam stabilizer is included in an amount of 1 to 10 parts by weight on the basis of 35 to 55 parts by weight of the polyvinyl chloride resin.

The present invention relates to cellular solid materials comprising cellulose nanofibers (CNF) and an anionic surfactant, a method for preparation of such materials, as well as their use.
