• Minerals used as fillers in plastic compounds have traditionally been used to reduce material costs by replacing a portion of the polymer with a less expensive material.
• Nowadays many functional fillers or mineral modifiers are required to modify processing characteristics or finished part properties.Many are now also being used to reduce the level of more expensive additives such as pigments, flame retardants and impact modifiers.
• Mineral fillers make up less than 6 percent of the hot mix asphalt concrete by mass, and generally less than about 3 percent. A typical mineral filler completely passes a 0.060 mm (No. 30) sieve, with at least 65 percent of the particles passing the 0.075 mm sieve.
• Minerals used in plastics include naturally occurring minerals such as calcium carbonate, talc, clays, barium sulphate, diatomite, mica and wollastonite, as well as synthetic grades and nano-sized minerals.
• Mineral fillers increase the temperature resistance of polymers such as polypropylene and polyamides, allowing them to compete with more expensive materials such as ABS or PBT, respectively, in applications such as automotive interiors.
• In the electronics area, which is growing at a rate of over 10% per year, minerals are being used to increase temperature resistance of plastics both during use and during fabrication.
• Minerals are added to WPC formulations to improve properties such as impact, heat distortion temperature, and creep under load. Minerals such as talc can also increase lubricity and improve processing. Use of flame retardant minerals, including alumina trihydrate, antimony trioxide, magnesium hydroxide, borates, and nanoclays, is increasing with the trend towards non-halogenated flame-retardants and increased use of flame retarded plastics in areas such as construction.
• Key physical characteristics of a filler include mean particle diameter, particle size distribution, aspect ratio, surface area, dispersibility, and inherent colour. While various minerals can be added to a polymer to obtain a given performance characteristic, each may differ in the amount of property enhancement as well as in variables such as loading level and cost.
• As a filler in fine printing papers alumina trihydrate increases opacity and brightness, and in paper coatings it imparts brightness, gloss and high ink receptivity.ATH is used as a reinforcing pigment in adhesives, where it improves cold flow properties and cohesion, and stabilizes pH.
• Paints and primers represent the largest use for filler-grade barite (barium sulfate). High brightness micronized barite is used as an extender to provide the weight that customers equate with quality, and because of its low binder demand for high loadings.
• Dry-ground calcium carbonates are among the least expensive white fillers available. Wet-ground products are produced in finer particle size ranges. Wet-ground fine and ultrafine products are also sold in 75% solids slurry form for highvolume paint and paper applications.Calcium carbonate is also the most widely used filler in adhesives and sealants.
