Coupling Agent

Coupling agent is a plastic additive that improves the interface properties of synthetic resins and inorganic fillers or reinforcing materials in plastic compounding, also known as surface modifiers. The coupling agent generally consists of two parts: one part is an inorganic group, which can interact with inorganic fillers or reinforcing materials; the other part is an organic group, which can interact with synthetic resins. According to the classification of chemical structure, the coupling agents used in industry can be divided into: silanes, titanates, aluminates, organic chromium complexes, borides, phosphates, zirconates, stannates, etc. They are widely used in the field of polymer materials such as plastics and rubbers.
