1, the mechanical strength and temperature resistance are different: the higher the vinyl content, the better the mechanical strength and temperature resistance of raw rubber. However, if the vinyl content is too high, the porosity in silica gel will also increase, thus affecting the performance and quality of silica gel.

2. Different uses: Silica gel with low vinyl content is often used to bond metals, nonmetals and other materials, while silica gel with high vinyl content is not suitable for large-area bonding, but if the proportion of fillers in silica gel is increased, the temperature resistance and weather resistance of silica gel can be improved.

3. Different prices: The price of low vinyl content silica gel is lower than that of high vinyl content silica gel.
