Does anyone know the viscosity of polyisobutylene?
Thread Content
Hello, everyone! Some customers need our high-viscosity gear pumps to transport polyisobutylene, and we can only provide a viscosity of around 100,000 cSt at 40 degrees Celsius. Could any friends provide the viscosity-temperature curve for this material? Thank you first! ! !
Viscosity needs to be measured experimentally, as the molecular weight (degree of polymerization) of the polymer directly affects its viscosity.
Our company sells polyisobutylene, and I have approximate curves; I’ll send them to you. Just now, a client wanted to ask for information
