Characteristics
Organic Hydrophilic Fumed Silica powder is a type of Silica Powder that has been treated to be hydrophilic, meaning it has
an affinity for water. This makes it an ideal additive for plastic materials, as it can improve the dispersion of fillers and
pigments, enhance the mechanical properties of the plastic, and improve its flow and processing characteristics.
Fumed Silica Powder is a highly versatile material that is used in a wide range of industries, including plastics, adhesives,
coatings, and cosmetics. Its small particle size and high surface area make it an effective thickening agent and reinforcement
filler for plastics, helping to improve their strength, stiffness, and impact resistance.
Organic hydrophilic Fumed Silica powder is particularly well-suited for use in plastic materials that come into contact with water,
as its hydrophilic properties can help to improve the material's resistance to moisture and water absorption. It can also improve
the adhesion of the plastic to other materials, such as adhesives or coatings.
Overall, organic hydrophilic fumed silica powder is a valuable additive for plastic materials, offering a range of benefits that can
help to improve their performance and durability.
