Dispersed PVC Resin
White fine powder
Polyvinyl chloride paste resin, also called dispersed PVC resin, is a fine white powder designed to disperse in plasticizers. Its small primary particles produce homogeneous plastisols for coating, impregnation, and casting. Applications include artificial leather, wallpaper, vinyl toys, gloves, automotive interiors, adhesives, and coatings requiring a workable paste-based processing route.![Xylene]( "Xylene")
XyleneXylene
Colorless liquid
Xylene is a clear, colorless aromatic hydrocarbon liquid with a characteristic odor. Insoluble in water but compatible with many organic solvents, it dissolves resins, oils, and rubber while providing useful evaporation behavior. It serves as a coating thinner, ink solvent, resin-processing medium, adhesive ingredient, and industrial cleaning solvent.![Ethyl acetate]( "Ethyl acetate")
Ethyl acetateEthyl acetate
Colorless liquid
Ethyl acetate is a clear, colorless ester solvent distinguished by its fruity odor and rapid evaporation. It mixes with ethanol, ether, and other organic solvents while having limited water solubility. Its solvency for oils, resins, and organic materials supports coatings, printing inks, adhesives, extraction, leather processing, and industrial cleaning.![Sodium Lauryl Ether Sulfate(SLES)]( "Sodium Lauryl Ether Sulfate(SLES)")
