Application recommendation SYLOID® 244FP Application:
SYLOID® 244FP is a high pore volume gel with a large internal surface area.It has a strong affinity for mositure.SYLOID® 244FP can adsorb up to 1.6 ml of a liquid per gram.It is particularly recommended as a free flow additive for pharmaceutical products and as a carrier for liquid products.It has excellent compatibility with active ingredients.
Application recommendationSYLOID® AL-1 FP Application:
SYLOID® AL-1 FP is a kind of low pore volume gel, the inner specific area is large. Under low temperature, it has great moisture absorption ability.
In pharmaceutical industry, SYLOID® AL-1 FP is recommended to be used as flow aid to control the minimum relative moisture. It has great compatibility to the active element of the liquid. |
