Specialty Minerals Products in Reinforced Polyolefins for Appliances
Increasingly, manufacturers of large household appliances such as
washing machines, dishwashers, and refrigerators are turning to
reinforced polyolefins—primarily polypropylene—for use in component
parts. Mineral fillers are needed in these parts to give the required
balance of performance and cost.
Minerals in Appliance Polyolefins
and fine talcs and ground calcium carbonates (GCCs) are
commonly used in polypropylene components in appliances.
functional minerals, talcs improve flexural modulus (stiffness), heat
and dimensional stability, and processability. They add opacity and
improve surface finish. Talcs also act as nucleating agents, which, when combined with their thermal properties, yields faster cycle times
and improved production rates. By replacing more expensive ingredients,
talc can reduce total part cost.
GCCs are excellent fillers for economy
and resin extension. Die scrubbing, better and faster processing, and
increased opacity are additional contributions made by these minerals. Coated fine ground calcium carbonates can also improve impact strength.
