JH-756 MBS Toughening Agent / Impact Modifier for PC, PC/ABS | METABLEN S-2501 & Kaneka MR-502 Alternative
JH-756 MBS Toughening Agent / Impact Modifier for PC, PC/ABS | METABLEN S-2501 & Kaneka MR-502 Alternative
JH-756 — Premium MBS Toughening Agent / Impact Modifier for PC & PC/ABS
JH-756 is the flagship MBS (Methyl Methacrylate-Butadiene-Styrene) impact modifier in the JH series, delivering the highest impact strength (778 J/m at 23℃) and the lowest yellow index (0.06) in the range. It is a direct, cost-competitive replacement for both METABLEN S-2501 (Mitsubishi Chemical) and Kaneka MR-502 (Kaneka, Japan).
🏆 Key Advantages
- Direct replacement for METABLEN S-2501 and Kaneka MR-502
- Highest impact strength in JH MBS series: 778 J/m at 23℃ and 685 J/m at -30℃
- Ultra-low yellow index: 0.06 — exceptional color purity, virtually colorless
- Highest heat resistance in JH MBS series: HDT 120.3℃, Vicat 140.8℃
- High stiffness: flexural modulus 2548 MPa
- Excellent surface gloss: 105 GU at 60°
🔬 Applications
- High-end PC and PC/ABS alloys requiring maximum impact performance
- Automotive parts demanding both toughness and color purity
- Electronic enclosures and components requiring superior heat resistance
- Medical and optical applications requiring near-zero yellowing
- PMMA/SAN alloy systems requiring impact improvement with light transmittance
