Deskripsi Produk

Description
 
    Methylcellulose is a non-ionic cellulose ether, which is produced by etherification by introducing methyl groups into cellulose.
Methylcellulose is a cellulose  White or light yellow or light gray small particles, filamentous or powder. Odorless and tasteless, with approximately 27% to 32% of hydroxyl groups present in the form of methoxy groups. Different levels of methyl cellulose have different degrees of polymerization, ranging from 50 to 1000; And its molecular weight (average) ranges from 10000 to 22000 Da, and its degree of substitution is defined as the average number of methoxy groups, which are connected to each glucose anhydride unit on the chain.

Physical and Chemical Properties
1,Appearance: White or quasi-white fibrous or granular powder, odorless and tasteless.

2,Solution: Almost insoluble in ethanol, ether, (1: 1) in the mixture can form a clear or suspended viscous solution. In 80-90 ºC hot water rapid swelling, cooling after rapid dissolution, water dissolution at room temperature is quite stable, high temperature gel, It undergoes a reversible transition from gel to dissolution after heating and cooling.

3,Characteristics: Excellent wettability, dispersion, adhesion, thickening, emulsifying, water-holding and film-forming, and oil impermeability. The film has excellent toughness, flexibility and transparency. Because it is non-ionic, it can be compatible with other emulsifiers, but it is easy to be salted out and the solution is stable in the range of pH 2-12.

4,Density: 1.3g/cm;Apparent density: 0.25-0.7 g/cm³.
5,discoloration temperature: 190-200ºC.
6,Carbonization temperature: 225-230ºC.
7,Surface tension: 47-53 dyn/cn.
