Oil absorption is an important technical index for Aluminum Hydroxide as a filler in polymer compound.
1.aluminum hydroxide filler’s particle shape and particle size distribution will greatly influence the oil absorption. As an additive, under the premise of the same particle shape, the lower the oil absorption, the lower the viscosity in the production process.
2.since the particle size distribution is basically identical, particle shape is the main factor affecting the oil absorption. Other influence factors are measuring temperature, stirring time, stirring method, etc.
