Problems solved by technology

However, silicone rubber has certain deficiencies in terms of strength, acid resistance, and alkali resistance; at the same time, with the vigorous development of society, all walks of life have higher and higher requirements for the comprehensive performance of silicone rubber and its products, especially for some applications. There is an increasing demand for high-performance materials with certain functions under extreme conditions (such as high and low temperatures, acid-base environments, etc.), and traditional silicone rubber products can no longer meet people's requirements. Sexual enhancement is imperative
