Slack Wax 5% Oil Content

Description

1. Product Overview

Slack Wax 5% Oil Content is a semi-refined paraffinic wax fraction, derived from petroleum base oils, with a tightly controlled oil content of 5%. It is primarily used as a cost-efficient intermediate feedstock for producing refined paraffin wax, candle blends, and moisture-resistant board coatings. The key value proposition is its balance between purity and price, delivering predictable performance for large-scale industrial conversion. Strategically, it enables buyers to reduce raw material costs while maintaining downstream processing flexibility in volatile paraffin markets.

2. Key Specifications & Technical Characteristics

• Chemical composition: Paraffinic hydrocarbons (C18–C40), <5% oil by weight

• Purity level: 95% minimum paraffin content; oil content 5% ±0.5%

• Physical characteristics:

  • Form: Soft, semi-solid slab or pastille

  • Color: White to off-white (ASTM D6045 ≤3.0)

  • Kinematic viscosity (100°C): 4–7 cSt

  • Congealing point: 50–54°C (ASTM D938)

  • Density (20°C): ~0.80–0.82 g/cm³

• Packaging options: 25 kg bags, 500 kg flexible bulk bags, or bulk containers

• Shelf life: 24 months in dry, shaded conditions (below 40°C)

3. Core Industrial Applications

• Primary industries: Candle manufacturing, paperboard coating, rubber protection (antiozonants), and paraffin wax refining

• Operational use cases:

  • Direct blending with hard paraffin for economical candle production

  • As a sizing agent in corrugated board to improve moisture resistance during shipping

  • Feedstock for solvent dewaxing to produce fully refined paraffin (oil <0.5%)

• Performance advantage: The precise 5% oil content minimizes smoke during candle burning and reduces volatile emissions in board coating lines. Compared to higher-oil slack wax (6–8%), this product improves final product gloss and hardness, yet costs 20–30% less than fully refined wax.

4. Competitive Advantages

• Quality consistency: Lot-to-lot congealing point and oil content variation <±0.3% – traceable via GC-MS certificates

• Supply reliability: Multiple refinery sources with 50,000+ MT annual dedicated capacity

• Logistics capability: Bulk flexibag, ISO tank, or break-bulk shipping available from 3 global hubs (Rotterdam, Houston, Singapore)

• Price competitiveness: Fixed quarterly pricing or spot-linked formulas available for contract volumes >500 MT

• Sustainability: Reprocessed from refinery streams; supports circular economy goals (no virgin crude cracking)

• Technical support: Full SDS, batch COA, and application lab access for blend optimization

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (one truckload or less-than-container load consolidation)

• BULK loading capacity: 24–26 MT per 20ft standard container (bulk bagged palletized); 21–23 MT per ISO tank
