## About

Selective Absorption Fusion (SAF) Polypropylene (PP) is an industrial-grade, powder-bed fusion polypropylene engineered for high accuracy and cost-effective production. SAF PP enables durable, lightweight parts with outstanding chemical resistance, flexibility, and watertightness. It’s perfect for air- and fluid-handling applications, living hinges, consumer goods, and any use case demanding strong, ductile, and chemically resistant components.
