Pure rubber has low mechanical strength—blending it with nano-silica (UG-SR01) as a reinforcing filler boosts the tensile strength of vulcanized rubber, playing a key role in enhancing final rubber performance. Ideal for reinforcing high-temperature vulcanized (HTV) and room-temperature vulcanized (RTV) silicone rubber, it forms silica-centered microcrystalline regions to increase physical crosslinks. It also acts as an anti-aging agent, improving rubber strength, toughness, wear resistance, and service life. Smaller particle size, larger specific surface area, and higher structure enhance its reinforcing effect.
