Product Features
- Dual Internal and External Lubrication: Reduces intermolecular friction (internal) while minimizing melt adhesion to equipment metal surfaces (external).
- Excellent release properties — low adhesion between part and mold ensures complete ejection and superior surface finish.
- Excellent thermal stability — does not decompose below 240°C, suitable for standard PP/PE/PVC processing temperatures.
- No bloom, no exudation — excellent compatibility with resins; no surface migration or exudation over extended storage.
- Improve product surface gloss — enhance finish and smoothness of injection-molded and extruded parts
- High-performance domestic lubricant with excellent value. Delivers performance comparable to leading imported brands, with stable supply and fast delivery.
Application Areas
Rigid PVC — Extruded Profiles, Pipes, and SheetsFlexible PVC — Cables, hosesPP/PE Injection Molding — Daily Goods & Packaging ContainersEngineering Plastics — ABS/PA/PBT Modified SystemsRubber Processing — EPDM/NBR Rubber-Plastic Mold ReleaseMasterbatch / Filler Masterbatch — Enhances Carrier Resin Flowability and Dispersion
App Data
| Applicable Systems | Recommendation | Behavior Description |
|---|---|---|
| Rigid PVC | ✅ Recommended | Use 0.3-0.8 phr to improve flowability and surface finish. |
| Flexible PVC | ✅ Recommended | Use 0.1-0.3 phr to prevent roller sticking and improve release. |
| PP | ✅ Recommended | Add 0.1-0.5 phr to improve melt flow and reduce screw torque. |
| PE | ✅ Recommended | Use 0.1-0.5 phr to improve processability and reduce energy consumption. |
| ABS | ✅ Recommended | Use 0.2-0.6 phr to improve release and enhance surface gloss. |
| PA | ⚠️ Use with Caution | Use 0.2-0.5 phr to improve flow and aid demolding. |
| Rubber | ✅ Recommended | Dosage: 0.5-1.0 phr; release and anti-stick |
Notes
- Please test with a sample first to confirm the optimal dosage and heat resistance conditions.
- The powder color chart may differ from the final product color. Please refer to the actual colored result.
- Evaluate weather resistance for long-term outdoor exposure.
