Common Name(s): Synthetic polymer,rheology or film-forming modifier,performance polymer

CAS Number: N/a

DESCRIPTION

What It Does: Provides polymer-based thickening, film formation, or emulsion stabilisation through the specific molecular weight and monomer composition.

Why It's Used: Synthetic polymers deliver precisely engineered performance unavailable from natural biopolymers — molecular weight, composition, and architecture are controlled for specific application outcomes.

How It Works: Polymer chain entanglement and network formation above overlap concentration c* provides viscosity. film formation by solvent evaporation above tg. crosslinked networks provide yield stress gel for suspension stabilisation.
