JH-721 MBS Toughening Agent / Impact Modifier for PC, PC/ABS & PMMA | Kane Ace M-721 Alternative
JH-721 MBS Toughening Agent / Impact Modifier for PC, PC/ABS & PMMA | Kane Ace M-721 Alternative
JH-721 — MBS Toughening Agent / Impact Modifier for Engineering Plastics
JH-721 is a core-shell structured MBS (Methyl Methacrylate-Butadiene-Styrene) impact modifier synthesized by emulsion graft polymerization. It is a direct, cost-competitive replacement for Kane Ace M-721 (Kaneka, Japan), delivering outstanding low-temperature toughness, excellent surface gloss, and broad compatibility with engineering plastic systems.
🏆 Key Advantages
- Direct replacement for Kane Ace M-721 (Kaneka, Japan) at a more competitive price
- Outstanding impact strength: 733 J/m at 23℃ and 640 J/m at -30℃
- Significantly improves low-temperature toughness of PC and PC/ABS alloys
- Maintains dimensional stability and load-bearing capacity at elevated temperatures
- Excellent surface gloss: 105 GU at 60°
- Very low yellow index: 3.25 — superior whiteness and color consistency vs. JH-701
- Adjusts refractive index in PMMA/SAN systems — improves impact while preserving light transmittance
- Compatible with POM modification for broadened application scenarios
🔬 Applications
- PC and PC/ABS alloys requiring low-temperature toughness
- PMMA/SAN alloy systems requiring impact improvement with light transmittance
- POM modification for broadened application scenarios
- Automotive parts, electronic enclosures, and high-end engineering plastic components
