Ultra-High Molecular Weight Homopolymers for Critical Applications

Our Ultra-High Molecular Weight Homopolymers meet the needs of industrial processes that require consistent flow performance, reliable stability, and controlled molecular behaviour. 

Our UV-RAFT process is capable of producing Ultra-high molecular weight that is not possible to make using traditional processes. Our library of Ultra-high MW PAM includes homopolymers with narrow-distribution molecular weight of 35MDa to 140MDa.

These formulations use precision polymerization techniques to produce ultra-high molecular weight (UHMW) polyacrylamide products with exceptional viscosifying and friction reduction properties.

Whether applied in Oil & Gas Hydraulic Fracturing operations as a Friction Reducer or a viscosifier, the UHMWPAM solutions ensure strong performance even under harsh and challenging process conditions.

PolyPAM UHMWPAM formulations achieved exceptional friction reduction of over 70% in a high brine solutions of 225k TDS, using very dilute loading of 0.1 kg/m3. These formulations also achieved excellent dissolution properties, reaching full solubility within a minute.

Viscosifiers in Salty Environment

  • Salt-tolerant molecular design
  • Stable viscosity under harsh conditions
  • Compatible with produced and recycled water

Comparison of viscosity profiles in a 200k TDS salt solution

PolyPAM’s UHMW formulation maintains high viscosity in high salinity environments. This property is critical for viscosifying applications, and especially in Hydraulic Fracturing applications where the polymer must act as a Friction Reducer as well as a good viscosifier.

Backed by Research

At PolyPAM, every product is backed, meaning you don’t just get a high-MW label; you will get measured performance across shear, salinity, and temperature tolerances.

Our Ultra-high MW PAMs meet regulatory, sustainability, and operational efficiency goals, especially in settings where chemistry must deliver under pressure.
