Slack Wax 5%

Description

1. Product Overview

Slack Wax 5% is a semi-refined paraffin wax derived from petroleum base stocks, containing a controlled 5% oil content by weight. It is primarily used as a processing aid, binder, or moisture barrier in industrial compounding and forming operations. The key value proposition is its optimal balance between hardness and ductility, which reduces cracking in finished goods while maintaining low melt viscosity. Strategically, Slack Wax 5% occupies a critical mid-tier position in the wax market, offering a cost-effective substitute for fully refined paraffin in non-food-contact applications where strict oil limits are not required.

2. Key Specifications & Technical Characteristics

• Chemical composition: Paraffinic hydrocarbon blend (C18–C40) with 5.0% ±0.5% oil content

• Purity grade: Semi-refined / Industrial grade

• Physical characteristics:

  • Form: Pastille or slab

  • Color: White to off-white (Saybolt +20 min)

  • Melting point (drop melt): 52°C – 56°C

  • Penetration (25°C, 100g/5s): 25–35 0.1mm

  • Density at 70°C: 0.78 – 0.82 g/cm³

  • Kinematic viscosity (100°C): 5.0 – 7.0 cSt

• Packaging options: 25 kg woven PP bags, 50 kg slabs, 850 kg jumbo bags, or bulk truck/train loading

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

3. Core Industrial Applications

• Primary industries: Rubber manufacturing, candle production, wood panel processing, asphalt modification, and construction materials

• Operational use cases:

  • Rubber compounding – functions as a processing aid, reducing internal friction and mold sticking

  • Candle blending – controls hardness and opacity when mixed with lower-grade waxes

  • Particleboard and MDF – acts as a moisture repellent in wax emulsions

  • Hot melt adhesives – modifies open time and set speed

• Performance advantage over alternatives: Unlike fully refined wax (0.5% oil), Slack Wax 5% offers better flexibility and adhesion in rubber compounds. Compared to higher-oil slacks (e.g., 10–15%), it reduces bleed-out and surface tack while maintaining lower cost than fully refined grades. This translates to 12–18% lower formulation cost for non-critical moisture barriers.

4. Competitive Advantages
