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.
