Name: Addivant ROYALTUF 485 Coupling Agent
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Addivant ROYALTUF 485 Coupling Agent

Enhances interfacial adhesion between inorganic fillers (e.g., silica, calcium carbonate) and organic polymer matrices.
Improves mechanical properties including tensile strength, flexural modulus, and impact resistance in filled thermoplastics and thermosets.
Offers excellent hydrolytic stability due to its silane-based dual-reactive functionality with alkoxy and vinyl groups.
Enables reduced filler agglomeration and improved dispersion during compounding and extrusion processes.
Compatible with a broad range of resins including polyolefins, engineering plastics, and unsaturated polyesters.

Typical Applications Of Addivant ROYALTUF 485 Coupling Agent

Reinforced polypropylene (PP) and polyethylene (PE) compounds for automotive interior and under-hood components.
Mineral-filled PVC formulations used in rigid construction profiles and cable jacketing.
High-performance composites based on glass fiber or mineral fillers for industrial and electrical applications.
Thermoset systems such as epoxy and phenolic resins for molded electrical insulators and friction materials.
Masterbatch production where consistent filler-matrix coupling is critical for downstream processing performance.
