RENU™ PPS NAT-MP### is the custom-mesh version of PolyClean’s natural PPS powder, available across the 20–170 mesh range. All physical, thermal, chemical, and electrical properties match TDS-011; the variable is particle size distribution. Custom PPS mesh sizes are particularly valuable for fluidized-bed coating operations and thermal spray applications where specific particle size ranges optimize coating quality and uniformity.

RENU™ PPS NAT-MP140 is a precision-milled polyphenylene sulfide (PPS) powder produced from clean post-industrial natural (unfilled) PPS scrap. PPS is a semi-crystalline engineering thermoplastic offering excellent chemical resistance — one of the broadest in the engineering plastics category — combined with dimensional stability, inherent flame retardancy, and good electrical properties. The 140-mesh grade is well-suited for powder coating of chemical-resistant components, compression molding, and as a polymer matrix in industrial composite applications. RENU™ PPS provides an economical path to PPS performance.
