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.
Coupling Agents
Coupling agents enhance bonding between inorganic and organic phases, improving compatibility, adhesion, and mechanical integrity in composites, coatings, rubber, and fillers. Silane, titanate, and aluminate coupling agents are widely used to optimize interface performance and enhance material strength.
Zeolite
Zeolites are porous aluminosilicate materials used as catalysts, adsorbents, ion exchangers, and molecular sieves. Their uniform pore structure supports cracking, isomerization, purification, and gas separation processes. They are indispensable in petrochemical refining, environmental treatment, and industrial adsorption technologies.
Flame Retardants
Flame retardants inhibit or delay combustion in plastics, textiles, coatings, and electronic materials. They operate through heat absorption, char formation, or radical interference, significantly improving fire safety. Their use is essential in building materials, electronics, transportation, and consumer products.
Petrochemicals
Petrochemical auxiliaries include cracking catalysts, polymer additives, refinery chemicals, and separation media used in fuel production and petrochemical processing. They improve reaction efficiency, product purity, and operational stability, serving as critical inputs in large-scale chemical manufacturing.
Other Auxiliaries
This category includes multifunctional additives such as stabilizers, dispersants, leveling agents, rheology modifiers, wetting agents, and processing aids. They enhance formulation stability, manufacturing efficiency, and end-product performance across coatings, plastics, inks, and chemical processes.
