Performance

1. Good stability;
2. Good water retention;
3. Good dispersibility;
4. Good thickening.

Usage

1. All models can be added to the material by dry mixing method;
2. The need to add directly to the normal temperature aqueous solution, the best use of cold water dispersion type, after adding generally for 10-90 minutes to thicken;
3. The common model first uses the hot water to stir disperses, joins the cold water to stir cools dissolves;
4. When the phenomenon of caking and wrapping occurs when dissolving, it is because the agitation is not sufficient or the common model is directly added to the cold water, it should be stirred quickly.
5. When the bubble is dissolved, it can be settled for 2-12 hours (determined by solution consistency) or by vacuum, pressurization, etc., or by adding a proper amount of defoaming agent.

Customization

HuaMao® can customize according to customer demand, production of goods.
1. HuaMao® can customize the packaging according to the customer's requirements.
2. HuaMao® can produce HPMC which is the special technical index, according to the customer's demand.

This product is water-soluble ether, with the characteristics of hot gel, that is, excellent cold water soluble and hot water insoluble characteristics; it is a nonionic mixed cellulose ether with no ionic charge, no interaction with metal salts or ionic compounds, PH stability, strong enzyme resistance and metabolic inertia, and good dispersion, emulsification, thickening, Bonding, water retention and adhesive properties.
