PFA Color Concentrate
Get to Know Everflon+™ PFA Color Concentrate
Everflon+™ PFA color masterbatch is a concentrated pellet in which high-quality pigments and any performance additives are pre-dispersed in a PFA carrier resin. The masterbatch is blended into virgin PFA (typically at 2–10% addition) during processing so manufacturers can achieve repeatable color and consistent functional properties without compromising the base polymer's behavior.
Achieve vibrant, durable coloration without compromising the exceptional properties of PFA. Our high-performance PFA Masterbatch is expertly engineered to overcome the critical challenges of pigmentation, ensuring superior stress crack resistance, thermal stability, and processability for the most demanding industrial applications.

The Challenge of Coloring PFA
Coloring PFA is more demanding than many thermoplastics. Pigments behave like impurities in perfluorinated resins and can negatively affect melt stability and stress-crack resistance (SCR) if not selected and handled correctly. Achieving a successful PFA color or functional concentrate requires careful control of:
Resin match: Masterbatch carrier must be compatible with the target PFA grade and melt flow index (MFI/MFR). Mismatch causes processing issues and poor dispersion.
Pigment choice & loading: Choosing pigments that tolerate PFA processing temperatures and keeping concentrations appropriate for wall thickness and end use are critical. Typical loading ranges are 2–10 wt% depending on color depth and application.
Dispersion quality: Uniform, fine dispersion is essential to avoid localized weak points that cause melt fracture or premature cracking in service.
Processing window control: Compounding and extrusion temperatures, residence time and shear must be optimized to prevent pigment or carrier degradation.
