Aerosil Powder
Aerosil Powder is a highly versatile fibreglass filler known for its exceptional thickening and thixotropic properties. It is primarily used in the manufacturing of gel coats, resins, and paints to improve flow properties and prevent sagging during application. This makes it highly valuable in the automotive, marine, and aerospace industries where precision and durability are paramount. Moreover, its ability to enhance the bonding strength of composites makes it an indispensable choice for the production of high-performance parts and components.
Dolomite
Dolomite acts as a cost-effective filler that offers both utility and performance in fibreglass manufacturing. Characterized by its high strength and durability, it is a popular choice for bulk filling applications where additional weight and rigidity are required. This natural mineral is extensively used in the construction sector, particularly in the production of composite countertops, flooring tiles, and architectural panels. Besides offering structural benefits, dolomite enhances the thermal resistance of composites, making it suitable for high-temperature applications.
Fillite
Fillite is a form of cenospheres, or hollow ceramic microspheres, that serves as a lightweight filler in fibreglass compositions. Its primary appeal lies in its ability to reduce the weight of composite materials without sacrificing mechanical strength. The automotive and aerospace industries benefit significantly from Fillite’s inclusion, as it contributes to fuel efficiency by minimizing the weight of components. Furthermore, its thermal insulation properties find applications in fire-resistant doors and panels, contributing to the safety of buildings and vehicles.
Wollastonite
Wollastonite stands out for its unique needle-like structure, providing excellent reinforcement in fibreglass composites. This mineral filler not only enhances the mechanical strength of materials but also improves their heat resistance and dimensional stability. It is particularly advantageous in applications requiring precision and durability, such as in the electronics and automotive industries. Wollastonite is also favored for its environmental benefits, as it can partially substitute for asbestos in many applications, providing a safer alternative for producing friction products and insulating materials.
