Main Products
Diphenylamine
Diphenylamine Flakes

Liquid Diphenylamine
Mainly used in the synthesis of polymerization inhibitors (e.g., phenothiazine), alkylated diphenylamine or lubricant antioxidants, as well as rubber antioxidants, dyes, pharmaceuticals, pesticide intermediates, etc., and can also be used as propellant stabilizers.
Phenothiazine

An excellent polymerization inhibitor for olefinic monomers, widely used in the production of acrylic acid, acrylates, methacrylic acid and its esters, vinyl acetate, etc.
Used in the synthesis of pharmaceuticals and dyes, polyethers, antioxidants, and rubber antioxidants.
Used as livestock deworming agents, fruit tree insecticides, etc.
Antioxidant KY-405

Anti-aging agent for natural rubber and synthetic rubbers such as styrene-butadiene, isoprene, chloroprene, and butyl rubber; also used as an antioxidant in plastic masterbatches such as polyethylene, polypropylene, and polyvinyl chloride.
Acts as an antioxidant for polyurethane foam, rubber wires, cables, food packaging materials, and adhesives.
Especially in chloroprene rubber colored cable sheaths, it exhibits significant protective performance against heat, light, and aging..
Copper Salts


Used as a polymerization inhibitor in the production of monomers such as butyl acrylate, octyl acrylate, high-carbon methacrylate, and other unsaturated olefins.
