PROCEDURE FOR OBTAINING FLEXIBLE EXPANDABLE MATERIAL (FEM) RESISTANT TO COMBUSTION USING BIOPLASTIFICIZERS
The present invention is a novel fire-resistant material used for the manufacturing of pipe collars as passive fire protection. The technological process consists of two phases. The first phase involves mixing poly (vinyl chloride-co-vinyl acetate) copolymers (VC-co-VAc) or a modified poly(vinyl chloride-co-vinyl acetate) copolymer (VC-co-VAc) with expandable graphite and plasticizers/modifiers such as: diisononyl phthalate—DINP, dioctyl adipate—DOA, 1-hexadecene or methyl esters of soybean fatty acids (MBS), azodicarbonamide (ADC), tri-p-cresyl phosphate, tri-m-cresyl phosphate or tri-o-cresyl phosphate, epoxidized soybean oil (ESO) and polyacrylate or poly(vinylacetate) emulsion. The second phase considers shaping the resulting mixture in a temperature-controlled press to make various samples, which are further tested. The samples had different dimensions: 4-6 mm thickness, 70-400 mm width and 240-500 mm length.
Polymer coated metallic substrate and method for making
A composite material comprising a metallic substrate and a coating on at least one side of the metallic substrate, wherein the coating comprises an acrylic or styrene-acrylic based polymer and is less than about 0.2 mils thick, wherein the polymer has a molecular weight of 50,000 to 1,000,000, a glass transition temperature (Tg) of 50-80° C., and comprises 90-100 wt. % of the total solids in the coating. The method of applying a coating to a metal substrate using a manifold flood and squeegee roll configuration or alternatively roll coater techniques; wherein the roll hardness, shape, pressure and speed are chosen to ensure that the coating composition forms a continuous wet film on the metallic substrate surfaces when the strip travels at up to 600 feet per minute; and the wet film has a uniform thickness of 2 mil (0.002 inch) or less.
POLYIMIDE-FORMING COMPOSITIONS, METHODS OF MANUFACTURE, AND ARTICLES PREPARED THEREFROM
A polyimide-forming composition includes a particulate polyimide precursor composition having an average particle size of 0.1 to 100 micrometers wherein the polyimide precursor composition comprises a substituted or unsubstituted C.sub.4-40 bisanhydride, and a substituted or unsubstituted divalent C.sub.1-20 diamine; an aqueous carrier; and a surfactant. A method of manufacturing an article including a polyimide includes the steps of forming a preform comprising the polyimide-forming composition; and heating the preform at a temperature and for a period of time effective to imidize the polyimide precursor composition and form the polyimide. An article prepared by the method, and a layer or coating including a polyimide and a surfactant are also described.
POLYMERS INCLUDING A METHYLENE BETA-KETOESTER AND PRODUCTS FORMED THEREFROM
The present teachings are directed at 1,1-disubstituted alkene monomers (e.g., methylene beta-ketoester monomers), methods for producing the same, polymerizable compositions including a methylene beta-ketoester monomer, and polymers, compositions and products formed therefrom. The monomer preferably is a high purity monomer. In the method for producing the methylene beta-ketoesters of the invention, a beta-ketoester may be reacted with a source of formaldehyde. The methylene beta-ketoester monomers may be used in monomer-based products (e.g., inks, adhesives, coatings, sealants or reactive molding) and polymer-based products (e.g., fibers, films, sheets, medical polymers, composite polymers and surfactants).
PAI-BASED COATING COMPOSITIONS
A process for PAI-based coating compositions. An embodiment of a method includes manufacturing a coating composition, the manufacturing of the coating composition including mixing a first solvent, the first being solvent being N-formyl morpholine (NFM), with a second solvent to form a first solution; dissolving polyamideimide or polyamide amic acid resin polymer (PAI) in the first solution; precipitating a PAI compound from a mixture of MEK and the first solution; and dissolving the PAI compound in a second solution to generate a coating solution.
