What is the mean cps in the hpmc cellulose viscosity ?
china manufacture hydroxypropyl methyl cellulose HPMC CAS 9004-65-3
HPMC is
Hydroxypropyl methylcellulose and another named is hypromellose, also simplified as hydroxypropyl methylcellulose (HPMC), is a kind of non-ionic cellulose mixed ether.
Usually we can see the unit CPS in the viscosity , but what is the mean CPS? please check following:
CPS is Brinell Viscosity Unit.CPs are also commonly used as a unit to indicate the viscosity of the glue, i.e. millipa seconds. The measurement methods of viscosity can be divided into absolute viscosity and relative viscosity. Absolute viscosity can be divided into dynamic viscosity and kinetic viscosity. The unit of dynamic viscosity is Pa s (Pa seconds), 1Pa s = 1Kcps, and 1cps = 1mPa s.
so hydroxypropyl methyl cellulose HPMC 15cps meaning the viscosity is 150000 . and the someone show the viscosity is 150000cps is wrong , it is 15 cps .
hpmc cellulose 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
