Hydroxypropyl Methyl Cellulose (HPMC) 1.Surface tension:42-57 2. Water, wt%: 5.0 max 3. Fineness, mesh: 120, 100,80
Hydroxypropyl Methyl Cellulose (HPMC) Functions:HPMC is good non-ionic mixture fiber ether, and has good dispersion, thickening, water reservation and others. It can be widely used in food, cosmetics, ceramic, battery, pesticide, marker, pencil core, water based ink, leather, gum lac, textile, tobacco and so on.
Application:It is widely 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. lt also used in petroleum drilling and daily-use chemicals
Solution method:1. Get needed hot water according to different specification products.2. Put 1/3 or 2/3 hot water to add into fiber while mixing.3. HPMC has good solution, and is easy to dissolve in concrete, dye and other to get expected effect.
Packing, storage and cautions:Hydroxypropyl Methyl cellulose is packed in paper plastic lined with polyethylene plastic bag or paper drum. Net weight is 25kg or 20kg. Hydroxypropyl Methylcellulose should be stored in dry conditions
