118 Properties of Adhesion Promoters

Outstanding properties: improved adhesion between glass filler and the nylon matrix. At low
concentrations of 3.5-7%, increased Notched Izod impact strength of the glass-reinforced nylon
by as much as 30 to 50%, also reduced compound melt viscosity for improved mold filling and
better surface appearance of the glass-filled molded parts. Filled compounds can retain more of
their mechanical properties such as tensile strength, modulus, and heat deformation temperature.
Improved strength and increased moisture resistance in wood/polyethylene composites at signifi-
cantly lower usage levels than conventional maleic anhydride coupling agents. It provides superior
performance and dramatic reduction in water absorption. Balanced attraction between polar fillers/
reinforcements and non-polar polymers. Increased most physical properties of fiberglass-rein-
forced nylon composites. Increased the strength of composites that utilize reinforcements/fillers
such as glass, talc, calcium carbonate, and metals. Optimized interfacial tension, stabilized mor-
phology against high stresses and enhanced adhesion between the phases in the solid state. Com-
patibilization improved the mechanical properties of the polymer blend.
