Ethylene urea-manufacture,factory,supplier from China

Due to the shortcomings of urea formaldehyde resin such as terrible preliminary viscosity, massive shrinkage, excessive brittleness, water resistance, handy aging, launch of formaldehyde, and air pollution of the surroundings and injury to fitness in the course of curing, it is integral to regulate it to enhance its overall performance and increase its application.

Main purposeEthylene glycol dimethyl acrylate is frequently used in the plastic and rubber industries as a crosslinking agent for ethylene acrylic copolymers, ABS, acrylic sheets, pipes, glass fiber bolstered polyester, PVC, ion trade resins, smokeless powder encapsulation polymerization, glazing, etc. is additionally used as a polymer in copolymerization, which will increase hardness, warmness resistance, climate resistance, solvent resistance, and friction resistance.

Polyvinylpyrrolidone, additionally acknowledged as PVP, is a polymer of ethylene pyrrolidone. Due to its unique ranges of polymerization, it can be divided into soluble PVP and insoluble PVPP (polyvinylpyrrolidone). The relative molecular weight of soluble PVP is 8000~10000, which can be used as a precipitant to precipitate by way of reacting with polyphenols. By the usage of this method, there are effortlessly residual PVP in the wine.

The relative molecular weight of soluble PVP is 8000~10000, which can be used as a precipitant to precipitate with the aid of reacting with polyphenols. By the use of this method, there are without problems residual PVP in the wine.

Application1. Used as formaldehyde trapping agent to remove formaldehyde remaining in fabrics after finishing by 2D-resin, KB-resin, urea-formaldehyde resin, melamine-formaldehyde resin, etc. It is also used as an intermediate of fine chemicals, used in the manufacture of resins, plasticizers, spray paint, adhesives, etc.2. used as formaldehyde capture agent, intermediate of fine chemicals, also used in the manufacture of resins and formulation of plasticizers, spray paint, adhesives and other uses for the synthesis of chiral microporous materials prepared from non-chiral precursors;3.

Ethyl acetate is a broadly used satisfactory chemical product with incredible solubility, fast drying, and a large vary of uses. It is a very essential natural chemical uncooked cloth and tremendous industrial solvent, and is extensively used in the manufacturing procedure of acetate fiber, ethyl fiber, chlorinated rubber, ethylene resin, acetate fiber resin, artificial rubber, coatings, and paints.

Polyvinyl alcohol resin (PVA) aqueous answer has awesome moldability and emulsifying properties, forming a movie with amazing adhesion, solvent resistance, friction resistance, tensile strength, and oxygenbarrier properties.Solubility: Soluble in water, typically heated to 65-75 ℃ for whole dissolution. Insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, etc. Slightly soluble in dimethyl sulfoxide.
