It dissolves at ordinary temperature in water or in any organic solvents, such as absolute methanol, ethanol, isopropanol propylene glycol and methylence chloride, also in acetone, chloroform, toluene or cellosolves. The solution is very clear and transparent.

HPC is a highly thermoplastice substance and shows an excellent film forming property. The film obtained is very tough. Ash content is exceedingly low, so that the product has excellent binding property, stabilizing property for viscosity-increasing emulsions and in dispersibility.

HPC shows no medicinal action by itself, has no toxlcity and is physiologically harmless.

HPC is chemically inert, so that it hardly reacts with other reagents.

The addition of antifungous agents is not necessary when HPC is used.

Equilibrium moisture content of H-HPC is low.

Process for dissolving H-HPC

Dissolving in water

HPC is introduced little into water being stirred vigorously, dissolving is difficult if all the amount is added at once.

20% to 30% of a prescrided amount of water is heated to a temperature above 60 centigrade and HPC is slowly introduced under the remaining 80% to 70% water is added, by this process, quick dissolving is realized.

Dissolving in organic solvents

HPC is slowly introduced into the organic solvent under sufficient stirring, dissolving is difficult if all the amount is added too quickly.

Main uses of H-HPC

1. Use as binders: In the pharmaceutical field, as a binder for tablets, granules and fine grains or as the pase of ointments. It is used in an amount of 1% to 5% by weight of the medicine.

2. As film-coating agents; HPC has an excellent film-forming property. The film obtained in tough and flexible and has a noticeably good compatility with plasticizers, the film-forming property coating agents, maybe further impoved by using together with other moisture-proy.

HPC is used as dispersing agent for PVC, plasticizer absorbing property is improved, so that particles of uniform size are obtained. Compatibility with plasticizers, extrusion property is improved. Formation of so called "fish-eyes" is inhibited. It is used as a viscosity-increasing agent for pyinting inks, cosmetics, paint removers, dry cells etc, and as binder for ceramics. HPC is used as gelation agnts for water and alcohols, especially for solidifying aocoholic solutions of perfumes to obtain solid perfumes having a delivery-retarding effect.

HPC is further used for fiber-treating agents, mortar and ancrete mixing agents and for paper coating agents.

Package, storage, transportation

It is packed in cardboard drum and lining with polyethylene film bag. Net weight 25kg per drum. Storgeand transportation: Well-closed, direct sunshine and raining and moisture must be avoided.

Brief introduction

The luminescent film is researched and produced by ourselves. Which have excellent effects of storing any visible light and glowing. After absorbing visible light for 10 to 30 minutes, they can glow in the dark for 12 hours at least. And it can be repeated any times for storing and glowing process. And they have good performance of enduring weather with non-toxic and harmless and no any radioactivity.

The luminescent film with self-adhesive can be used onto the surface of varied equipment or article, which use is the same with hard board, even more is more convenient. Such as it can be cut into many kinds of shapes or signs and put onto the place where need. Anyway it is useful and novel. For example, it is used in furniture decoration or put onto the surface of switch, telephone, handle, stationery, toy, sport article or indication in the public area, recreation ground.

Functions:

1. High fire retardedness by use of illuminating film made by PVC plastics

2. High capacity of saline resistant and detergent resistant

3. High capacity in cold/heat resistance

4. High mechanical functions for illuminating films

5. Strong sticking ability for illuminating films.

Usage Procedure:

1. Preferably to be applied for construction on smooth surface with the temperature of 10~40C

2. Cut the film into different sizes and can be directly pasted to the places like switch for decoration use.

3. Figure/ character printed on the surface.

4. Clean the surface clean before pasting. No grease mark or dust allowed on the surface.

5. The film is expandable. Be careful not to dispose it at will and recommended to keep it pressed.

6. It is prone to humidity. Preferably have it processed in environment with 40%-60% in humidity.

7. Remove the paper from back and press neatly on the surface.

8. At times, the products with different batch numbers have color differences.

9. The color films of MY, MR, MB and MG are recommended not to be used outside.

10. The film at length of 10m is likely to have junctions.

Packing and Storage

1. Packing; Curly or slice shape for handi-wrap.

2. Storage: Keep in warehouse where is ventilated, dry and cool with temperature between 15Cand30Cand relative humidity between 40% and 60%.

Million Killer 601s is the most effective anti-bacterial material, produced by Japan WAKO Chemical Ltd.

As the best inorganic anti-bacterial material, it is composed with silver ion and glass. The silver ion kills bacterial effectively, and will not be consumed by bacterial, so it lasts almost life long.

It doesn't affect the transparency of plastic (glass containing silver), for this, it can be used in all the plastic.

Million Killer 601s is used widely in plastic, textile, painting, toys, food package, etc. Dosage of only 0. 3% is enough to maintain a life-long 100% anti-bacterial.

Comparing with other silver anti-bacterial material, Million Killer posseses the advantages:

1. Keeps high transparency of plastic.

2. Stable quality, it releases silver ion at a stable speed in standard testing, so it kills bacterial steadily and permantly.

3. Very low dosage added (0.3% is adequate normally).

4. Safe & environment protective (LD50>2000mg/kg).

5. Humidity resistant (absorption of moisture: 0.4% in humidity of 81%, 24 hours).

1. Food grade of Glycine is mainly used as nutritional supplement and food additive
