JH-768 MBS Impact Modifier for Transparent ABS (PMMA/SAN) | Kaneka M-733A & Mitsubishi C-223A Alternative
JH-768 MBS Impact Modifier for Transparent ABS (PMMA/SAN) | Kaneka M-733A & Mitsubishi C-223A Alternative
JH-768 — MBS Impact Modifier for Transparent ABS (PMMA/SAN Systems)
JH-768 is a core-shell structured MBS (Methyl Methacrylate-Butadiene-Styrene) impact modifier specifically engineered for transparent PMMA/SAN blends (transparent ABS). It is a direct, cost-competitive replacement for Kaneka M-733A and Mitsubishi C-223A, delivering matched refractive index, excellent impact performance, and high optical clarity.
🏆 Key Advantages
- Direct replacement for Kaneka M-733A and Mitsubishi C-223A at a more competitive price
- Matched refractive index — maintains high transparency in PMMA/SAN blends
- Good impact strength: 113 J/m at 23℃ in PMMA/SAN system
- High stiffness: flexural modulus 2748 MPa
- Easy processing with good fluidity (MFR: 23.2 g/10min at 220℃, 10kg)
- High whiteness: L value 95.27, low yellow index 5.45
🔬 Applications
- Transparent PMMA/SAN blends (transparent ABS)
- Styrene copolymer toughening requiring optical clarity
- Transparent packaging, consumer electronics covers
- Optical components requiring impact resistance with light transmittance
