Catalysts and Auxiliaries
Catalysts and Auxiliaries
Catalysts and auxiliaries encompass substances that accelerate chemical reactions, regulate polymer behavior, modify material properties, or enhance processing efficiency. This category includes precious-metal catalysts, polymerization catalysts, coupling agents, antioxidants, UV absorbers, flame retardants, brighteners, and plastic–rubber auxiliaries. Catalysts enable high-selectivity synthesis, lower reaction energy, and improve industrial productivity. Auxiliaries support stabilization, crosslinking, aging resistance, and performance enhancement in polymers, coatings, textiles, and electronic materials. Together, they form essential components in chemical manufacturing, petrochemicals, advanced materials, and specialty processing industries.
Polyethylene Glycol Derivatives
PEG derivatives function as surfactants, solubilizers, dispersants, humectants, and reaction intermediates in pharmaceuticals, cosmetics, coatings, and polymer modification. Their excellent water compatibility and flexible molecular design make them valuable across numerous formulation systems and chemical processes.
Fluorescent Brighteners
Fluorescent brighteners absorb ultraviolet light and re-emit it as visible blue light, enhancing whiteness and brightness of textiles, detergents, plastics, and paper. They improve product appearance by counteracting yellowing and enhancing visual clarity. High stability and strong fluorescence efficiency are essential for industrial applications.
Precious Metal Catalysts
Precious metal catalysts-such as those based on platinum, palladium, rhodium, and gold-enable highly efficient hydrogenation, oxidation, coupling, and fine-chemical transformations. They play essential roles in pharmaceuticals, petrochemicals, electronics, and environmental processes. Their high activity and selectivity make them indispensable in advanced catalytic technologies.
