JH-736 MBS Impact Modifier for POM Toughening | Kaneka M-231 & Formosa M51 Alternative
JH-736 MBS Impact Modifier for POM Toughening | Kaneka M-231 & Formosa M51 Alternative
JH-736 — MBS Impact Modifier for POM (Polyoxymethylene) Toughening
JH-736 is a core-shell structured MBS (Methyl Methacrylate-Butadiene-Styrene) impact modifier specifically engineered for toughening polyoxymethylene (POM). It is a direct, cost-competitive replacement for Kaneka M-231 (Kaneka, Japan) and Formosa M51 (Formosa Plastics, Taiwan). With just 5–15% addition, it boosts POM notched impact strength from 64 J/m to 91 J/m (+42%).
🏆 Key Advantages
- Direct replacement for Kaneka M-231 and Formosa M51 at a more competitive price
- Significant toughening effect: impact strength 64 → 91 J/m (+42%) at just 10% addition
- Outstanding elongation at break: 177.4% — dramatically reduces POM brittleness
- Excellent POM matrix compatibility — MMA shell provides strong interfacial adhesion, no phase separation
- Maintains material modulus: flexural modulus 1925 MPa after toughening
- Low dosage required: only 5–15% addition for significant improvement
- Good processing fluidity (MFR: 5.41 g/10min at 190℃, 2.16kg)
- High gloss: 87 GU at 60°
🔬 Applications
- POM (Polyoxymethylene / Acetal) toughening and brittleness improvement
- Automotive POM components requiring impact resistance
- Industrial gears, fasteners, and mechanical parts
- Consumer electronics and appliance POM components
