The method of distinguishing silica gel and ordinary rubber is complex. Infrared spectrum analysis can scientifically determine the type of corresponding material through different absorption peaks. But for consumers, it can only be identified through the senses. Generally speaking, silica gel products are colorless and tasteless, and transparent without pigment. If different dyes are added, black silica gel and color silica gel can also be obtained. But rubber products have more or less a taste.
Natural rubber itself has a taste of protein, while rubber processed with sulfur has a special taste. As for some people judging by the softness, they think that silicone is softer than rubber, which is wrong. Because ordinary rubber or resin materials through different additives can also achieve the same softness as silicone products.
