Plastic Lumps / Purges
Bulk Raw Material for Grinding into Regrind
Our Plastic Lumps / Purges represent bulk, unprocessed plastic material in solid, irregular chunks. This stream typically originates from machine purges, startup/shutdown waste, or solidified material from various industrial processes. Ideal for buyers with robust grinding capabilities, these lumps offer a cost-effective source of polymer once converted into usable regrind.
Key Characteristics
Core attributes and inspection points for Plastic Lumps / Purges
| Characteristic | Detail | Importance for Buyer |
|---|---|---|
| Form | Solid, irregular, dense lumps/blocks | Requires heavy-duty grinding and shredding equipment |
| Polymer Type | CRITICAL: Must be specified (e.g., PP Lumps, HDPE Lumps, LDPE Lumps) | Determines chemical, thermal, and mechanical properties |
| Color | CRITICAL: Must be specified (e.g., Natural, White, Black, Mixed) | Directly affects end-use coloring and compounding options |
| Source | Post-Industrial (PIR) typically | Generally cleaner, less contaminated than PCR streams |
| Contamination | Low (single-stream) to Moderate (multi-product purges) | Should be inspected for foreign materials or mixed polymers |
