High-density polyethylene (HDPE blow-molding resin)

Description

1. Product Overview
This High-Density Polyethylene (HDPE) blow-molding resin is a high-molecular-weight thermoplastic engineered for the continuous production of hollow, impact-resistant industrial containers. Its primary application lies in manufacturing blow-molded articles such as jerry cans, industrial drums, and automotive fluid reservoirs. The key value proposition is its exceptional environmental stress crack resistance (ESCR) combined with high rigidity, enabling lighter-weight packaging without compromising stack strength. Strategically, this resin is critical for supply chains transitioning to durable, recyclable plastics, offering a direct replacement for less sustainable or heavier materials in logistics and chemical containment.

2. Key Specifications & Technical Characteristics

• Chemical Composition: High-density polyethylene homopolymer / copolymer (per buyer specification); CAS 9002-88-4

• Purity/Grade: Virgin blow-molding grade; ≥99% polyethylene; no regrind, no filler

• Physical Characteristics:

  • Form: Spherical or cylindrical pellets (2–5 mm)

  • Color: Natural (translucent white) / Custom colors available

  • Density: 0.954 – 0.962 g/cm³ (ASTM D1505)

  • Melt Flow Index (MFI): 1.8 – 4.0 g/10min (190°C/2.16kg) – optimized for parison sag control

  • ESCR (ASTM D1693): >1,000 hours (Condition B, 10% Igepal)

• Packaging Options: 25 kg moisture-barrier bags; 750 kg FIBCs (super sacks); 1,250 kg gaylord boxes

• Shelf Life: 24 months when stored indoors in original sealed packaging, <50°C, <70% RH

3. Core Industrial Applications

• Primary Industries: Chemical & hazardous goods packaging, lubricants & automotive fluids, household & industrial cleaning products, food-grade container manufacturing (non-oily), and agricultural chemical storage.

• Specific Use Cases:

  • Industrial drums (20–220L): Superior hoop strength and top-load resistance for stacking in supply chains.

  • Jerry cans: Excellent drop-impact resistance even at -20°C, critical for logistics handling.

  • Automotive reservoirs (coolant, washer fluid): Resists under-hood temperatures and long-term contact with glycol-based fluids.

• Why this product performs better: Its controlled bimodal molecular weight distribution delivers faster cycle times (15–20% reduction) than standard unimodal HDPE, while maintaining higher melt strength to prevent wall thinning. This translates to: lower energy consumption per part, reduced scrap rates (<2%), and ability to down-gauge containers by 8–12% without failure.

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified production with real-time SPC monitoring; each lot includes a Certificate of Analysis (CoA) for MFI, density, and ESCR.

• Supply reliability: Multiple feedstock-secured manufacturing sites (Asia-Pacific, Middle East) with 50,000 MT monthly capacity; 98.5% on-time-in-full (OTIF) track record.

• Logistics capability: Bagged or bulk truck/container loading; anti-humidity lining for ocean freight; warehouse hubs in Rotterdam, Houston, and Shanghai.

• Price competitiveness: Direct-from-manufacturer pricing with volume-based tiering; no hidden additives or filler markup.

• Sustainability: 100% recyclable (SPI Code #2); options for ISCC PLUS certified mass-balanced bio-circular or chemically recycled content available at premium.

• Technical support: Free process optimization audit (screw design, air cooling settings, mold venting) included for orders ≥100 MT.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 metric tons (MT) – equivalent to one full truckload (FTL) or 20-ft container.

• Bulk 20 MT: Standard commercial lot – allows full CoA traceability and facilitates blending homogeneity.
