Viscosity modifiers
Viscosity modifiers will influence the flow behavior of amorphous materials, XIBOND® can act as processing aid to optimize the viscosity for several processes such as blow molding or extrusion.

Viscosity modifiers can increase or decrease the viscosity of certain polymers. Viscosity modification does not occur via a chemical reaction, however. Because of a miscibility range in polymers such as styrenics and acrylics, a difference in molecular weight enables a difference in flow behavior. The viscosity modification can act as a processing aid for several processes, such as blow molding or extrusion.
The XIBOND® Viscosity modifiers can influence the flow behavior of various polymers such as ABS, T-ABS, PMMA and PVC. When XIBOND® is (partially) miscible with a polymer matrix, it can lead to altered flow behavior due to a difference in the molecular weight of the products. For example, by increasing the flow of PMMA with XIBOND®, the PMMA is more applicable in an extrusion process. When using a XIBOND® with low molecular weight, the flow of, for instance, ABS and T-ABS will increase.
