Product features
Combizell®、Tecpoly® are easily soluble in cooling water instead of hot water. They are non-ionic cellulose ether which is compatible with many surfactants and polymers such as starch, guar and alginate.

Combizell®、Tecpoly® are pseudo plastic. Certain solutions behave thixotropic property. Solution viscosity relates with temperature and the viscosity drops when the temperature is going up. When it is up to gel temperature, polymer appears gelatinization and flocculation and this is reversible during cooling. Viscosity keeps stable in the wide PH range.

Combizell®、Tecpoly® cellulose ether behaves many features such as water retention, thickening, stability, conglutination, strong adhesion, protection colloid, suspension and latex stability as well as film formation. It is typically used for construction, coating, suspending polymer, ceramics, tobacco, cleaning and washing agent.

Packaging and storage
Combizell®、Tecpoly® cellulose ether is 25kg per bag, 20 bags per pallet (500kg). It is not easily rotten. We suggest following the principle of first in, first out at the warehouse. Keep original packaging and Keep dry, clean and far off hot resources where stored the goods. The products behave moisture absorption. The packaging bags are specially selected with water-proof. However, water content will go up if the storage condition is not dry enough. Shelf life for the product is no more than two years.

Combizell® 、Tecpoly®、Herancel®(only for Turkey)  are classified as:

◇ MC Methyl cellulose
◇ MHEC Methyl hydroxylethyl cellulose
◇ MHPC Methyl hydroxylpropyl cellulose
◇ Modified methyl cellulose

In the product nomination, F stands for special chemicals used for ceramics, G stands for special chemicals used for pharmaceuticals, CK stands for personal care application, the postfix with R stands for hydration and solution retardant.
