Using polymers as rheology modifiers – keeping the flow under pressure


Rheology modifiers are used to change the way in which matter flows and how materials react under pressure. Crucial to many industries and processes, they alter viscosity and add or change the functional characteristics of products. Rheology modifiers are also important in manufacturing processes, c...
