Tpnb/ Tripropylene Glycol Normal Butyl Ether CAS: 55934-93-5

TPNB glycol ether is a very slow-evaporating, hydrophobic glycol ether with outstanding surface tension-lowering ability; ideal where high polymer solvency and residence time are required. 

TPNB is the slowest-evaporating member of the family of  glycol ethers. 

TPNB is a high boiling, colorless solvent with low viscosity and practically no odor.

Due to its length and hydrophobic structure,  TPNB has a high organic solubility, low water solubility, and a high boiling point.

Izinzuzo

Sinezimboni eziningi zekhwalithi ephezulu ngokubambisana okujulile, ezingakunikeza ngemikhiqizo yekhwalithi ephezulu namanani ancintisanayo. Futhi singanikeza izaphulelo zokuthenga ngobuningi.Futhi sibambisana nezinkampani eziningi ezichwepheshile zokudlulisa impahla, zingaletha imikhiqizo ngokuphepha nangokushelela ezandleni zakho. Isikhathi sokulethwa cishe yizinsuku ezi-3-20 ngemuva kokuqinisekiswa kwenkokhelo.
