Products Description
Introduction and application of CAS:9047-50-1|DIALDEHYDE STARCH
Dialdehyde starch is a kind of oxidized starch, which can be obtained by oxidizing starch with periodic acid and its salt. Since dialdehyde starch has many active aldehyde groups, it has excellent physical, chemical and biochemical properties. It is widely used in papermaking , textile, building materials, leather, medicine, adhesives, coatings, degradable plastics, saponification, food and other industries.
Note: This product is easy to absorb moisture after opening the package, so the remaining materials after use should be tightly bagged to prevent moisture absorption. If moisture absorption and agglomeration of materials are found to affect the quality, they can be crushed and used.
