PAI Virgin Powder — Custom Mesh

RENU™ PAI VIR-MP### is the custom-mesh version of virgin (fully cured) PAI powder. Available across the
20–170 mesh range for applications requiring non-standard particle size distributions — large-part
compression molding, coarse thermal spray, or fine-precision molded parts. Properties match TDS-013; the
specified variable is particle size.
Available Mesh Sizes
Mesh Size Max Particle (μm) Typical Use
20 Mesh ≤ 850 μm Thermal spray, rotomolding, heavy coatings
40 Mesh ≤ 425 μm Flame spray, fluidized-bed coating
60 Mesh ≤ 250 μm Plasma spray, coarse compression molding
80 Mesh ≤ 180 μm Fluidized-bed, general compression molding
100 Mesh ≤ 150 μm Standard powder coating
120 Mesh ≤ 125 μm Precision powder coating
140 Mesh ≤ 105 μm Standard stock — SLS, compression molding
170 Mesh ≤ 90 μm Fine SLS, precision electrical applications
