RENU™ PEI LF NAT-MP140 is a low-flow grade polyetherimide powder milled to 140 mesh from post-industrial recycled PEI scrap. This grade shares the exceptional thermal, electrical, and flame retardant properties of the HF grade but is derived from lower-viscosity PEI feedstock. The lower flow characteristic makes this grade particularly suitable for compression molding and press-and-sinter processing where a more controlled, less runny powder is advantageous. All performance properties are equivalent to TDS-005 with the distinction being melt-flow behavior.

RENU™ PEI HF NAT-MP140 is a precision-milled high-flow polyetherimide (PEI) powder produced from clean post-industrial recycled PEI scrap. PEI is an amorphous, amber-colored engineering thermoplastic offering an outstanding combination of elevated-temperature performance, inherent flame retardancy (V-0 rating without additives), excellent electrical insulation, and broad chemical resistance. The 140-mesh cut delivers a free-flowing fine powder suitable for powder coating, SLS additive manufacturing, and compression molding of electrical and electronic components. At a fraction of the cost of virgin PEI, RENU™ PEI opens high-performance polymer applications to cost-sensitive industries.
