Siloxane-PTFE Masterbatch is a high-performance additive that combines the processing benefits of silicone (siloxane) with the anti-dripping effect of PTFE. It is designed for use in thermoplastic systems that require enhanced flow, surface quality, flame retardancy, and stability under high-temperature processing.
| Property | Typical Value |
|---|---|
| Appearance | White or light gray pellet |
| Siloxane Content | 10% – 30% |
| PTFE Content | 5% – 10% |
| Carrier Resin | PP, PE, PC, PA, or customized |
| Melting Point | Varies by carrier |
| Recommended Dosage | 0.2% – 2% |
| Problem | Solution via Siloxane-PTFE MB |
|---|---|
| Melt dripping during burning | PTFE network controls flow, passes UL94 V-0 |
| Surface swirl or gloss defects | Siloxane improves flow and finish |
| High friction in extrusion | Lubrication effect reduces shear stress |
| Poor mold release | Improves demolding and productivity |
Q1: Can this masterbatch be used in transparent products?
No, it may reduce clarity; not suitable for clear applications.
Q2: Is it suitable for food-contact plastics?
Food-grade versions are available upon request.
Q3: How should I choose the carrier resin?
Match the carrier resin to your base polymer (e.g., PP for PP, PC for PC).
