Brief Introduction:

1.Hydroxyethyl methyl cellulose HEMC LE100M is made from highly pure cotton cellulose. After alkali treatment and special etherification becomes HEMC. It does not contain any animal fats and other active ingredients.
2.Hydroxyethyl methyl cellulose HEMC LE100M is multifunctional additive for ready-mixes and dry-mix products. It is a high efficient water retaining agent, thickener, stabilizer, adhesive, film-forming agent in construction material.
3.The appearance of HEMC is white particles or powder, odorless and tasteless. It is hygroscopic and can not dissolve in hot water, acetone. ethanol and toluene. After swelling in cold water into a colloidal solution, dissolving is not affected by PH value. It is similar to methyl cellulose, but with the increase of hydroxyethyl groups, it has more tolerance, more easily soluble in water and has a higher condensation temperature.
4.Hemc plays a role of thickening, water retaining, which is very suitable for water based painting construction material, ink and oil drilling.
5.Good additive for powder materials. Used as gelling agent, water retaining agent of cent and gypsum.
