Description
Dorman® Insulating Glass Molecular Sieve (1.0–2.0 mm) is a high-strength desiccant specifically developed for insulated glass units requiring enhanced mechanical stability and moisture adsorption performance. It efficiently removes residual moisture inside IGUs, preventing condensation and ensuring long-term durability of sealed glazing systems. Its larger bead size provides improved mechanical strength and is suitable for both manual and semi-automatic spacer filling applications.
Spec & Technical Data
Dorman® Molecular Sieve 1.0–2.0 mm is composed of spherical potassium sodium aluminum silicate beads with optimized adsorption and strength characteristics for IGU applications. It offers high static water absorption (≥20%) with a bulk density of 0.72–0.78 g/ml and maintains a dew point below -73°C for effective moisture control. The product features higher crushing strength (≥15 N/piece), low gas adsorption (≤0.2%), and excellent size uniformity (≥98%). With low dust content (≤30 ppm) and residual moisture below 1.5%, it ensures stable, long-term performance in insulating glass systems while supporting both manual and semi-automated filling processes.
