RENU™ PEEK LF NAT-MP### provides the same flexible custom mesh sizing as TDS-003 in the low-flow PEEK grade. Milled from clean post-industrial low-viscosity PEEK scrap, this product covers mesh sizes from 20 to 170 mesh and is selected for applications where controlled melt flow during processing is important, combined with a non-standard particle size distribution. Ideal for compression molding of complex geometries, thermal spray with lower-energy systems, and research applications requiring specific particle size ranges.

TYPICAL APPLICATIONS
Note: RENU™ recycled powders are suitable for non-critical industrial, electronics, automotive, and commercial applications. They are NOT recommended for safety-critical aerospace structures or life-sustaining medical devices.
Application Area | Specific Uses |
Compression Molding (Large Parts) | Coarser LF grades preferred for large tooling where finer powders compact unevenly |
Thermal Spray (Low-Energy Systems) | LF grade coarser powders for lower-energy spray systems with larger nozzle orifices |
R&D Applications | Laboratory work requiring specific particle size ranges in lower-flow PEEK |
PACKAGING & AVAILABILITY
Format | Details |
Box (Standard) | Up to 25 kg (55 lbs) per box — double-wall corrugated with poly liner |
Drum (Bulk) | 68 kg (150 lbs) bulk drums — fiber or plastic drum with sealed poly liner |
Custom Packaging | Available on request for larger volumes — contact PolyClean for details |
Labeling | Each container labeled with: RENU™ product code, mesh size, lot number, and date of manufacture |
Processing Notes See TDS-003 for complete mesh size conversion chart. LF grade is preferred over HF where flash or bleed at parting lines is a concern in compression molding. |
