Mineral fillers and functional fillers are a variety of solid particulate materials that may be irregular, acicular, fibrous or plate-like in shape and which are typically used in reasonably large volume loadings.
The most commonly used particulate fillers are industrial minerals such as silica, talc, calcium carbonate, mica, kaolin, wollastonite, feldspar and barytes.
The choice of filler used in a specific application depends on the physical attributes of the mineral. For example, clay fillers used in polymer systems share some common features because of the plate-like shape of their particles, which results in some stiffening of the rubber compound. This gives much better extrusion and calendering properties (exhibiting low die swell and good dimensional stability) than can be obtained from most other mineral fillers.

Mineral fillers such as calcium carbonate and silica are used to improve the mechanical properties of materials like plastic, rubber, and paint, increasing durability and resilience.
By adding mineral fillers, manufacturers can reduce the cost of production by offsetting the amount of more expensive base polymers or resins required.
Certain mineral fillers are inherently flame-resistant, providing an added level of fire safety to materials such as textiles and construction components.
Mineral fillers help prevent shrinkage and distortion in materials, ensuring that products maintain their intended shape and size during and after the manufacturing process.
They can enhance the surface finish of products, enabling smoother application of paints and coatings, and contributing to the overall aesthetic appeal.
Mineral fillers can enhance the thermal conductivity of materials, which is particularly beneficial in applications requiring efficient heat dissipation, such as electronic devices.
By incorporating mineral fillers, products can often achieve desired performance characteristics without the need for additional processing, thereby reducing energy consumption and emissions.
Particle Size |
Mineral fillers typically have small particle sizes, which can enhance the surface quality and improve the mechanical properties of the final product. |
Density |
They usually exhibit a high density, contributing to the product's rigidity and weight. |
Thermal Stability |
These fillers provide excellent thermal stability, making them suitable for high-temperature applications. |
Chemical Resistance |
Mineral fillers often offer good resistance to chemicals, which helps protect the material in corrosive environments. |
Cost-Effectiveness |
They are generally cost-effective, providing an economical way to enhance product performance. |
Reinforcement Capability |
Mineral fillers can improve the strength and durability of composites by reinforcing the matrix material. |
Aesthetic Enhancement |
They can be used to modify the appearance and texture of products, offering aesthetic benefits. |
Non-Toxicity |
Many mineral fillers are non-toxic, making them safe for use in various applications, including food packaging and medical devices. |

Mineral fillers are finely ground natural or synthetic minerals added to materials like plastics, rubber, paints, and paper to improve their properties and reduce production costs.
Common mineral fillers include calcium carbonate, talc, silica, clay, and mica, each offering distinct properties suitable for various applications.
Mineral fillers can enhance the mechanical, thermal, and aesthetic properties of products. They may provide benefits like increased strength, reduced shrinkage, improved heat resistance, and altered surface texture.
Many mineral fillers are considered environmentally friendly as they are natural, abundant, and pose minimal harm during manufacturing and disposal. However, the overall environmental impact depends on the sourcing and processing methods used.
Industries such as automotive, construction, and packaging frequently use mineral fillers in the production of tyres, building materials, and plastic packaging to improve durability and reduce costs.
