Silica Gel Desiccant
Silica Gel Desiccant Packs are packed in strong, non-tearable Tyvek pouches designed to provide reliable moisture protection for hygroscopic products. They help protect sensitive goods from temperature changes, high impact, rattling, and variations in relative humidity during storage and long-distance transportation.
These macro-size packs are available in 25g, 50g, 100g, 250g, 500g, 1Kg, 2Kg, and 5Kg sizes for applications requiring higher moisture absorption. The silica gel packs are DMF-free and cobalt-free, with MSDS, SGS, and RoHS documentation available as specified.
