Hot Melt Adhesive (Glue)
Sodium Carboxymethy Cellulose （ CMC ）
DESCRIPTION
High Purity Sodium Carboxymethy Cellulose
CAS NUMBER 9004-32-4
Sodium carboxymethyl cellulose is white or yellowish powder that is odorless, tasteless and non-toxic. It has high hygroscopicity and is soluble in water to form thick liquid. It is a polyanionic electrolyte and is not fermented. It has good heat-stability, resistance to salt and film-forming characteristics. It is a strong emulsifier for fatty and oil.
The product is widely used in the industry of oil field darilling, textile, daily chemicals, building materials, ceramals, food and medicine as thickener, emulsifier, adhesive, excipient, protective colloid, etc.
HANDLING & STORAGE
Handling Handle in a well ventilated area. The fine particles and powder should be regarded as an inert, nuisance dust with a threshold limit value of 10mg/m- for total dust and of 3mg/m- for the respirable portion. Avoid static build-up when emptying big bags. Earth all equipment and attach a grounding cable to the bag grounding connection.
Storage Product should be stored, under cover, in a clean wet ventilated area. Maintain a clean area by removing dust. Keep away from heat, sparks and other sources of ignition. Store in a dry area.
PHYSICAL & CHEMICAL PROPERTIES
Typical data are:
Form Free flowing powder or granulate
Color Light cream to white
