How water and working environment affect polyurethane?
Views: 49 | Update Date: Jun 10 , 2019

How water and working environment affect polyurethane? Water has two effects on polyurethane elastomers. One is the plasticization of water, that is, water molecules enter into macromolecular chains and form hydrogen bonds with polar groups in polymer molecules, which weakens the interaction...

Discussion about oil and chemical resistance of polyurethane
Views: 69 | Update Date: May 30 , 2019

Generally speaking, the oil resistance of polymers refers to the general oil resistance including solvent resistance, which is in principle adapted to the expansion equilibrium formulation developed by Flory et al. That is to say, only expansion occurs, and only equilibrium of expansion occurs. Chemical...
