Paraffin wax

Description

1. Product Overview
Paraffin wax is a refined, crystalline hydrocarbon blend derived from petroleum, serving as a critical raw material for high-volume industrial processes including candle manufacturing, packaging, and rubber compounding. Its primary industrial use centers on providing a clean-burning, low-odor, and dimensionally stable medium for binding, coating, and molding. The key value proposition is its exceptional thermal stability, consistent melting profile, and cost efficiency—enabling predictable output at scale. Strategically, paraffin wax remains irreplaceable in global supply chains for food-safe packaging and specialty chemicals, offering a reliable price-to-performance ratio that synthetic or bio-based alternatives have yet to match at comparable volume.

2. Key Specifications & Technical Characteristics

• Chemical composition: Saturated straight-chain hydrocarbons (C18–C40), fully refined

• Purity level / grade: Fully Refined Grade (oil content ≤0.5% wt.), also available Semi-Refined and Slab Wax grades

• Physical characteristics:

  • Form: White, odorless, translucent slabs or pastilles

  • Melting range: 52°C–64°C (ASTM D87)

  • Congealing point: 50°C–62°C (ASTM D938)

  • Penetration (25°C): 13–20 (1/10 mm, ASTM D1321)

  • Density: ~0.88–0.92 g/cm³ at 25°C

• Packaging options: 25 kg multi-wall paper bags, 50 kg woven PP bags, 500–1,000 kg super sacks, or bulk molten tanker delivery

• Shelf life: 36 months when stored below 40°C, away from direct sunlight and strong oxidizers

3. Core Industrial Applications

• Candle manufacturing (primary): Provides excellent fragrance retention, uniform burning, and smooth mold release. Performs better than beeswax or soy wax in cost-per-unit and dimensional stability at high line speeds.

• Packaging & food coating: Used for moisture-proof coatings on corrugated boxes, cheese wheels, and fruit. Outperforms polyethylene emulsions in hot-melt application speed and FDA-compliant direct contact safety.

• Rubber & tire compounding: Acts as a processing aid and antiozonant. Delivers superior dispersion versus microcrystalline waxes at lower raw material cost.

• Wood & match production: Improves water resistance and friction control. Cost advantage over stearates for high-volume match splint treatment.

• Construction board (MDF/particleboard): Internal sizing agent that reduces water absorption. More consistent than slack wax for automated slurry mixing.

4. Competitive Advantages

• Quality consistency: Lot-to-lot variation <2% on melting point and oil content; certified by ISO 9001:2021 and third-party SGS testing available per shipment.

• Supply reliability: Multiple upstream refinery agreements (Middle East, Southeast Asia, Russia-alternative routes) with 98.5% on-time-in-full track record over 24 months.

• Logistics capability: Dedicated heated container fleet; ability to ship molten (65°C–70°C) in ISO tankers or solid slabs in standard 20’ containers.

• Price competitiveness: Direct ex-refinery pricing with volume-based quarterly adjustments; no hidden additives or filler dilution.

• Sustainability / environmental benefits: 100% recyclable process waste; chlorine-free refining; available with HCS (Hydrocarbon Solvent) low-aromatic certification.

• Technical support: Full documentation pack (CoA, SDS, FDA 21 CFR 172.886, REACH compliance, Halal and Kosher certificates) delivered within 24 hours of order confirmation.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 metric tons (MT) – equivalent to one full 20’ dry container of solid slabs or one ISO tank of molten wax.

• BULK 20MT: Standard truckload (solid) or ISO tank (molten) – 20 MT net weight.

• Loading capacity per container:

  • 20’ dry container (slabs/bags): 24–26 MT (max payload 28 MT depending on packaging)

  • 40’ dry container: 26–28 MT (theoretical max, subject to axle weight limits)

  • ISO tank container (molten): 20–24 MT net (heated, 60–70°C fill temperature)
