RENU™ PEI HF NAT-MP### is the custom-mesh offering of PolyClean’s high-flow PEI powder line. Available across the 20–170 mesh range, this product allows customers to specify the exact particle size distribution required for their process — from coarser grades for thermal spray and fluidized-bed coating to finer grades for precision SLS printing and fine-detail compression molding. All technical properties are equivalent to TDS-005; the variable is particle size. Contact PolyClean for availability and lead times.
