Construction grade Hydroxy propyl Methyl Cellulose
Hydroxy propyl Methyl Cellulose(HPMC) is widel used as thickener, adhesive, water preserving agent, film-forming agent in construction, building materials, dispersion coating, wallpaper paste, polymerization aids, leathers, printing ink and paper making etc.l also used in petroleum drilling and daily-use chemicals.
Packaging Detail: 1.Double-layer Bag, The product is packed in polyethylene film bag and then in PE bag. Net weight is 25kg per bag.
Specifications:
1.Appearance: HPMC is white or similar to white fiber or granular powder; odorless.
2.Properties: almost insoluble in ethanol, ether and acetone; quickly dispersed in 80-90 water; aqueous solution is very stable in room temperature; has good wetting/dispersing/adheisve/thickening/emlusifying/water preserving/film-forming properties; can prevent the infilration of grease; film formed has excellent flexibility and trransparency; has good compatibility with other emulsifier; easy salting-out. its solution is stable with PH 212. 3.Apparent density: 0.30--0.70g/cm3, density is 1.3g/cm3.
