Precipitated silica is an additive widely used in various industries, and its oil absorption value is an important indicator to measure its oil absorption performance. When downstream products use precipitated silica, the change in oil absorption value may have a certain impact on its performance and characteristics. Here are some possible effects:

Rheological properties: Precipitated silica is commonly used as a thickener and rheology modifier. A higher oil absorption value may cause it to absorb more liquid in the system, thereby affecting the rheological properties of the system. High oil absorption value may lead to increased viscosity of the system and poor fluidity.

Strength and hardness: In some industries and manufacturing processes, precipitated silica is used as a filler and reinforcing agent to increase the strength and hardness of the product. Variations in the oil absorption value may alter the oil content of the filler, thereby affecting the strength and hardness of the product.

Color and appearance: In some applications, precipitated silica is used to adjust the color and appearance of the product. Changes in the oil absorption value may affect its dispersion and uniformity in the product, thereby affecting the color and appearance of the product.

Adsorption performance: Precipitated silica is often used to adsorb impurities, pollutants and harmful substances. Changes in the oil absorption value may affect its adsorption capacity for target substances, thereby affecting the purification effect and adsorption performance of the product.

It should be noted that the oil absorption value of precipitated silica is only one of the parameters, and the performance of downstream products is affected by many factors, including formula design, production process and the use of other additives. Therefore, in practical applications, it is necessary to comprehensively consider various factors to evaluate the impact of oil absorption value on downstream products.
