polymer processing

I found polymer processing as something: new/fresh (it was for me, and it is comparing to tooling methods), exciting (later about it), growing (new: processes, tools, machines, materials, etc.) and mystery (viscoelasticity). It was about 10 years ago in Poland at Warsaw University of Technology. What I like in polymers the most? We know about the non-Newtonian characteristic of melted polymers. For that who are not familiar with basic terms for polymer processing I will prepare some more detailed information in the near future. Briefly it is non-linear characteristic between shear stress , and shear rate , known as a flow curve . For Newton fluids (ex. water, petrol, melted metals, etc.) the curve is straight and dynamic viscosity , (the most important term in polymer processing!!!) is constant. For melted polymers ( pseudoplastics fluids , viscosity falls with increasing shear rate) we can mark out tree characteristics stages for viscosity, linear for small shear rates, 1/10-10 [1/...

I would like to welcome everyone who is visiting the polymer processing’s blog. First of all I apologize for any language mistakes. I hope that I will be not prevent from supporting in helpful information and will not discourage you from visiting it. I am going to do one’s best. Why I decided to do it? I have started from http://www.tworzywa.blogspot.com/ this is about polymer processing. I understand you could not notice it because it is in polish. Most of my knowledge based on global sources and it is sometimes different from that I find in Poland. It is more complex. In this way of thinking about polymer processing I am away from that I see around and it sometimes helps but for this blog will be not competent. There are many others reasons but about them in the future. Both blogs will be living separate life because have different views. I hope meet from time to time. Both will be a record from my experience in the polymer processing field. Tools which I have explored, my point of ...
