Product Overview
EBS (Ethylene Bis Stearamide) is a high-performance synthetic wax additive manufactured through the condensation reaction of premium stearic acid and ethylenediamine. This multifunctional processing aid delivers exceptional lubricity and interfacial activity, making it an essential additive for polymer processing applications.
Key Features
1. Superior Lubrication Properties
- Significantly reduces coefficient of friction (μ≤0.1)
- Enhances polymer melt flow characteristics (30-50% MFI improvement)
- Delivers outstanding surface finish (Ra≤0.2μm)
2. Excellent Thermal Stability
- Thermal decomposition temperature ≥250°C
- Continuous service temperature range: -30°C to 200°C
- Volatile content <0.3% (200°C/2h)
3. Broad Material Compatibility
- Demonstrates excellent compatibility with polyolefins (PP/PE), engineering plastics (ABS/PC), and elastomers
- Maintains consistent performance in both polar and non-polar systems
Typical Applications
1. Polymer Processing
- Injection molding: Recommended dosage 0.3-0.8% for improved mold release
- Extrusion: Effectively eliminates melt fracture
- Blow molding: Enhances surface gloss (60° gloss ≥90GU)
2. Coatings & Inks
- Prevents pigment settling (>6 months shelf stability)
- Improves coating abrasion resistance (Taber abrasion ≤10mg/1000 cycles)
3. Personal Care
- Cosmetics: Enhances spreadability (contact angle ≤30°)
- Skincare: Improves silky feel (40% reduction in friction coefficient)
