Aluminum hydroxide is often used as a filler in PVC (polyvinyl chloride) compounds to improve their mechanical properties, such as tensile strength, stiffness, and impact resistance. When aluminum hydroxide is added to PVC, it forms a composite material that combines the mechanical properties of both the filler and the matrix material.
The addition of aluminum hydroxide to PVC compounds can increase their tensile strength and stiffness, as well as improve their impact resistance. This is because aluminum hydroxide is a hard and rigid material that can provide additional support and reinforcement to the PVC matrix.
However, the effect of aluminum hydroxide on the mechanical properties of PVC compounds is dependent on several factors, including the amount of filler added, the size and shape of the particles, and the processing conditions used. Excessive amounts of aluminum hydroxide can lead to decreased impact resistance and elongation at break.
In conclusion, aluminum hydroxide can have a positive impact on the mechanical properties of PVC compounds, but careful consideration should be given to the amount of filler added and the processing conditions used to ensure optimal results.
