Apply
Used as a dry adhesive for direct pressing tablets, adhesives for tablets, capsules and granules by wet process;
As an excellent film forming agent, it is used in the coating solution of tablets, particles, pellets and sugar-coated core and in the spray for local use. The film coating and spray film prepared with this product have good flexibility, low water absorption, high plasticity and low viscosity.
Good plasticity and low glass transition temperature make it suitable for the preparation of pharmaceutical solid dispersions by hot melt extrusion.
Improve the solubility and bioavailability of drugs;
Excellent adhesive for moisture-sensitive prescriptions;
Packaging and storage
25kg cardboard or plastic drum packing;
Store in a dry, airtight container.
