Name: Addivant POYBOND 1103 Coupling Agent
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Addivant POYBOND 1103 Coupling Agent

High-efficiency silane-based coupling agent specifically engineered for polyolefin–mineral filler interfaces.
Enhances interfacial adhesion between hydrophobic polymers and hydrophilic inorganic fillers (e.g., calcium carbonate, talc, glass fibers).
Improves mechanical properties including tensile strength, impact resistance, and flexural modulus in filled polypropylene (PP) and polyethylene (PE) compounds.
Thermally stable up to 300 °C, supporting high-shear compounding and extrusion processes without premature degradation.
Low volatility and excellent dispersion behavior, minimizing processing issues such as plate-out or die buildup.

Typical Applications Of Addivant POYBOND 1103 Coupling Agent

Automotive interior and exterior components (e.g., PP-based dashboards, bumpers, and under-hood parts).
Packaging materials requiring high stiffness and moisture barrier performance, including filled PE/PP films and containers.
Consumer durable goods such as appliance housings, lawn & garden equipment, and furniture components.
Industrial pipes and profiles where enhanced creep resistance and long-term dimensional stability are critical.
Recycled polyolefin composites, improving compatibility and property retention in post-consumer PP/PE blends.
