2.Performance

Tyrocell is a kind of important non-ion aqueous cellulose ether, the unique performance as below:

(1)Solubility in Water Tyrocell dissolves in water.

(2)Solubility in Polar Organic Solvent It can dissolve in polar organic solvents such as methyl alcohol, alcohol, chloroform, acetone etc.

(3)Hot Gelling Feature The water solution goes up or down with temperature, and takes on a reversible gelling process.

(4)Thermoplasticity The temperature of hot plasticity ranges between 130-150°C, within the range Tyrocell may be processed as plastic.

(5)Membrane Forming Tyrocell can form membrane with toughness, smoothness  and good elasticy.

(6)Cohesiveness lt has strong coherence, and is used as thickening agent in solution.

(7)Dispersiveness ıts water solution owns surface activity, providing effect of dispersion, emulsification and suspension.

(8)Anti-enzyme Property Owing to full reaction of substitution, the substitutive bases distribute homogeneous, HPC has comparatively strong anti-enzyme property and good resistance to bio-degradation.

(9)Hygroscopicity Tyrocell contains low average moisture.

(10)Liquid Crystal Reaction lts thick solution may form regular-directional liquid crystal.

(11)Safety Tyrocell has no medical effect, nor toxicity, with low ash, physiologically harmless, and offers inert to metabolism.

(12)Stability Tyrocell presents chemical inertia, stable even under lightly acidic or alkaline conditions.

IV.Usage

Tyrocell is used in industry mainly as disperser to produce PVC with suspension-method, such got PVC product presents uniform granule distribution, good plasticizing and adsorptive effect as well as excellent workability; used as thickening agent in oil-dissolving coating, glue bond, ing, cosmetics, paint remover, dry cells etc; used as controlled releaser in air freshening agent, solid spice, lavatory deodorant etc; used as fibre treatment agent, mixer of sand slurry and cement as well as coating agent for paper, protecting flim for metal surface; used in pharmaceutical industry as cohesive agent, pill coating, and low release agent; used as fresh-keeper for food, fruit and vegetables, and surface decoration for pastry, candy, chocolate with unique good effect.

V.Method of Use

1.Dissolve in Water

(1)Keep stirring, put Tyrocellslowly into water until fully dissolved.Adding too fast willmake difficult to dissolve.

(2)Heat 20-30% of the required water to around 60°C, gradually puy in Tyrocell while fully stirring, at last add in the left water, it can entirely dissolve.

2.Dissolve in Organic Solvent

While fully stirring, slowly put  Tyrocell into organic solvent (putting in one lump will make difficult to dissolve.)

3.Directly Use

Owing to Tyrocell’s very good thermoplasticity and compatibility, it can be used after hot shaping, also can be used kneading together with other ingredients in a su-itable proportion.

VI.Packing and Storage

20kg/25kg net wt.in carton drum, plastic-coated or paper-plastic compound bag lined with 2 inner PE bags.Store hermetically, prevent fire and wet.
