Product: Low-viscosity CMC (CMC-LVT)
Grade: Technical-Grade
Product Description: Technical-grade low-viscosity carboxymethyl cellulose (CMC-HVT) is an alkali metal salt of carboxymethyl cellulose
The product is a free-flowing or granulated powder
Product Physical Requirements:
CMC-LVT shall be deemed to meet the requirements of this international standard if a composite sample representing no more than one day's production conforms to the physical specifications of Table 13, represents the product produced and is controlled by LUDE CHEM
Technical Requirements:
CMC-LVT shall be free of any starch or starch derivatives. Therefore, a qualitative starch determination shall be performed before proceeding with the CMC-LVT performance testing.
