During the transportation of electronic goods, temperature and humidity fluctuate dramatically, easily causing moisture-sensitive electronic components to fail. According to the "Electronic Goods Transportation Environment Test Standard," humidity must be controlled between 25% and 65% RH during transportation, and desiccants must be resistant to temperature fluctuations. Shenzhen Ensobo Desiccant Co., Ltd., a manufacturer and exporter of electronic-grade desiccants, offers a combination of magnesium chloride and calcium oxide desiccants that effectively address this situation.
Ensobo's magnesium chloride desiccant is made from high-purity (99.5%) raw materials. After granulation, its moisture absorption performance fluctuates by ≤8% within the temperature range of -10°C to 50°C, making it suitable for the temperature fluctuations experienced during cross-border transportation of electronic goods. Calcium oxide desiccant, designed for high-humidity transportation environments (such as sea freight), can quickly reduce the humidity inside the package to below 20% RH and is non-corrosive to electronic components. As an exporter, our products have obtained International Electrotechnical Commission (IEC) humidity protection certification and have served over 20 electronics manufacturers worldwide. The company's OEM/ODM services can customize the mixing ratio of magnesium chloride and calcium oxide, as well as the packaging format (e.g., pouches, surface mount), based on the shipping cycle (7-60 days) and packaging sealability of electronic products. For example, a moisture-proofing solution developed for a laptop brand reduced the moisture-induced failure rate of electronic components during transportation by 90% by simulating the ocean shipping temperature and humidity curves and optimizing the desiccant dosage. This technical solution has been recognized by electronics industry technicians.
