Polyethylene Wax (PE Wax) is a synthetic wax derived from polymerization or thermal degradation of polyethylene.
It is a low molecular weight, highly crystalline material with excellent lubricity, heat resistance, and hardness. PE Wax is available in various forms such as flakes, granules, and fine powder, and is used as a performance-enhancing additive in numerous industrial applications.
Key Features
- High melting point (typically 100–120°C)
- Excellent thermal and chemical stability
- Superior lubrication and dispersing properties
- Enhances gloss, smoothness, and abrasion resistance
- Low viscosity and good compatibility with other materials
- Resistant to moisture and many chemicals
- Available in oxidized and non-oxidized forms
Main Applications
1. Plastics Industry
- PVC Processing: Acts as an internal and external lubricant, improving flow and preventing sticking.
- Masterbatches & Compounding: Assists in pigment and filler dispersion, enhancing surface quality.
- Polyolefins (PE, PP): Improves extrusion and molding performance, reduces die build-up.
2. Coatings & Paints
- Industrial and Wood Coatings: Adds scratch resistance, slip, and anti-blocking properties.
- Powder Coatings: Serves as a texturizing and flow control agent.
- Printing Inks: Improves rub resistance, surface slip, and gloss.
3. Adhesives
- Hot Melt Adhesives (HMAs): Enhances heat resistance, open time, and cohesive strength.
- Pressure-Sensitive Adhesives (PSAs): Controls tack and viscosity for better performance.
4. Rubber and Tire Manufacturing
- Used as a processing aid, lubricant, and mold release agent during compounding and molding.
5. Textile and Leather Finishing
- Provides water repellency, gloss, and soft feel in textile treatments and leather coatings.
6. Polish and Wax Formulations
- Common in automotive, floor, and shoe polishes for enhanced hardness and shine.
7. Printing & Packaging
- Enhances slip and scuff resistance of printed surfaces; used in overprint varnishes and flexible packaging.
8. Cosmetics & Personal Care (special grades)
- In food- or pharma-grade PE Wax, used as a thickener and film-former in balms and creams.
