PROCESS FOR PRODUCING LOW DENSITY GEL COMPOSITIONS |
摘要 |
Disclosed are processes for producing gel composition which may be utilized to produce low density gel compositions without the need for supercritical drying, thermal treatment or surface treatment. The processes comprise drying a wet gel comprising gel solids and a drying agent to remove the drying agent while minimizing shrinkage of the gel during drying.
