Discover our Blue Silica Gel in bags of 20kg or 500kg from Lianyungang Chemsize International Trading Co., Ltd. Perfect for moisture absorption.
Blue silica gel consists of blue or light blue glassy particles, categorized into blue silica gel indicator and blue silica gel. It exhibits hygroscopicity, transitioning from blue to purple to light pink as it absorbs moisture. This color change indicates humidity levels and the need for replacement. Blue silica gel can be used alone or in conjunction with Type A Silica Gel.
Primarily used for absorbing moisture and preventing rust in enclosed environments, such as instruments, gauges, and equipment. The color change from blue to red visually indicates the relative humidity of the surroundings. When combined with ordinary silica gel or a drier, it helps assess moisture absorption levels and determine relative humidity. Widely utilized as a desiccant for precision instruments, leather goods, shoes, clothing, food items, medications, and household appliances.
