Product Description

Product Description

Food grade silica gel desiccant

Food grade silicone desiccant is indeed a highly safe and versatile moisture-absorbing material, widely used in food packaging and other fields. 

1. Safety Performance
Non-toxic & Certified: Complies with FDA (U.S. Food and Drug Administration) and Chinese standard HG/T2765-2005, ensuring direct food contact safety. It is also SGS-certified for environmental friendliness.
Chemical Stability: Resistant to temperatures from -60°C to 250°C and inert to most substances except strong acids/bases, making it reliable for diverse environments.
2. Functional Features
High Moisture Absorption: Can absorb 30–80% of its own weight in water vapor without liquefying or deforming, thanks to its physical adsorption mechanism.
Microporous Structure: Silica gel's pores (8–10 nm) statically trap moisture without chemical reactions, ensuring stable performance.
3. Applications
Food Preservation: Prevents clumping/mold in dry goods like rice, seasonings, and snacks.
Daily Use: Effective for dehumidifying wardrobes, shoes, and electronics.
Industrial Uses: Humidity control in pharmaceuticals, precision instruments, and military equipment.
