PP Copolymer Regrind (PPCP)
The High-Impact, High-Flow Grade for Durable Applications
PP Copolymer Regrind (PPCP)
The High-Impact, High-Flow Grade
Our PP Copolymer (PPCP) Regrind is the essential material for high-impact applications. Chemically blended with ethylene during polymerization, this grade offers superior impact strength and flexibility, particularly at lower temperatures, where standard Homopolymer PP would become brittle.
Technical Snapshot & Specifications
Key properties and trading details for PPCP Regrind
| Specification | Primary Value | Key Trading Detail |
|---|---|---|
| Grade Type | Copolymer (PPCP / Co-PP) | Superior impact strength & flexibility |
| Material Source | Post-Industrial / Post-Consumer (Automotive trim, containers, battery cases) | Higher tolerance for filler/contamination than Homo-PP |
| Density | 0.895 – 0.905 g/cm³ | Slightly lower density than Homo-PP; very lightweight |
| Melt Flow Index (MFI) | 10.0 – 40.0 g/10min (at 230°C / 2.16 kg) | High flow; optimal for complex, thin-walled, or large parts |
| Color | Mixed (Jazz), Black, or Specific Compounds | Mixed color is economical; ideal for dark/black compounds |
| Processing | Excellent stability with minimal moisture concerns | Reduces processing defects and improves production consistency |

1. PP Copolymer Bucket Regrind
Durable Grade for High-Volume Containers
Our PP Copolymer Bucket Regrind is sourced primarily from post-industrial scrap (rejected food, paint, or chemical buckets/pails) or extremely clean Post-Consumer (PCR) streams. This material retains the superior impact strength and stiffness required to manufacture new, durable containers, lids, and industrial housings.
Technical Snapshot & Specifications
| Specification | Primary Value | Detail for Bucket Manufacturing |
|---|---|---|
| Grade Type | Copolymer (PPCP) | High impact; necessary for bucket handles, bases, and lids |
| Material Source | PIR / Clean PCR Buckets & Pails | High mechanical strength is retained from original end-use |
| Color | White, Grey, or Specific Solid Colors | Clean white/grey grades preferred for compounding or direct use |
| Melt Flow Index (MFI) | 8.0 – 15.0 g/10min (at 230°C / 2.16 kg) | Moderate flow; ideal for medium-thick walled buckets and lids |
| Density | 0.90 – 0.91 g/cm³ | Keeps final product weight low, minimizing raw material costs |
| Contamination | Low (PIR) to Very Low (Washed PCR) | Essential to avoid brittleness or weak spots in molded parts |
2. PP Copolymer Battery Regrind
Heavy-Duty, High-Impact Grade with Chemical Resistance
This PP Copolymer (PPCP) Regrind is sourced exclusively from spent automotive and industrial battery casings. The material is engineered for impact resistance and chemical exposure (sulfuric acid and lead). Its high mechanical performance makes it an ideal, cost-effective substitute for virgin PPCP in non-critical applications requiring extreme durability.
Technical Snapshot & Specifications
| Specification | Typical Value Range | Significance for Buyer |
|---|---|---|
| Grade Type | Impact Copolymer (PPCP) | High impact strength and rigidity for heavy parts |
| Source | Automotive / Industrial Battery Casings | Provides high chemical and stress crack resistance |
| Color | Solid Black | Consistent color; ideal for dark/black finished goods |
| Melt Flow Index (MFI) | 8.0 – 20.0 g/10min (at 230°C / 2.16 kg) | High flow for injection molding thick-walled components |
| Ash Content | High (3% – 6% max) | Often includes BaSO4 filler; enhances rigidity but must be measured |
| Lead Content | < 50 ppm (or required legal limit) | CRITICAL. Must be tested and certified clean of heavy metals |
3. PP Copolymer Filter Plate Regrind
Heavy-Duty, High-Impact & Chemically Resistant Grade
Our PP Copolymer Filter Plate Regrind is a highly specialized Post-Industrial Recycled (PIR) material, sourced directly from the manufacturing scrap of filter press plates and industrial filtration components. This PPCP grade is engineered for extreme durability, rigidity, and chemical resistance, designed to withstand high pressures and corrosive environments in its original application.
Technical Snapshot & Specifications
| Specification | Typical Value Range | Significance for Buyer |
|---|---|---|
| Grade Type | Heavy-Duty Impact Copolymer (PPCP) | Unmatched strength and rigidity; resists deformation under load |
| Source | PIR Filter Press Plates & Industrial Filtration Components | Clean, high-performance material from demanding applications |
| Color | Natural/White, Grey, or Specific Solid Colors | Neutral colors allow versatile re-compounding |
| Melt Flow Index (MFI) | 2.0 – 8.0 g/10min (at 230°C / 2.16 kg) | Low–medium flow; ideal for thick-walled, structural parts |
| Density | 0.905 – 0.920 g/cm³ | Reflects robust, high-strength formulation |
| Filler Content | Optional: May contain mineral fillers (e.g., Talc, CaCO3) | Enhances rigidity and dimensional stability; must be clearly specified |
| Contamination | Extremely Low (PIR) | High purity suitable for demanding industrial applications |
