Transparent Plastic Impact Modifier & Toughener for PMMA/SAN
Review RC-768 application tests for transparent PMMA/SAN and transparent ABS-type formulations at three distinct test addition levels.
Products for Evaluation
Short answer
RC-768 is the primary grade for evaluation in transparent PMMA/SAN and related transparent styrenic systems. Application tests are available at 20%, 25% and 28% addition levels. Optimum dosage depends on the resin system and target properties.
Application Test Evidence
| Property | 20% addition | 25% addition | 28% addition |
|---|---|---|---|
| Source formulation | PMMA / SAN / MBS = 40 / 40 / 20 | AS / PMMA / modifier = 37.5 / 37.5 / 25 | AS / PMMA / modifier = 36 / 36 / 28 |
| Izod | 113 J/m | 179 J/m | 200 J/m |
| Tensile | 51.8 MPa | 49.08 MPa | 45.5 MPa |
| Elongation | 53.9% | 28.98% | 27.81% |
| Flexural strength | 80.6 MPa | 77.9 MPa | 71.2 MPa |
| Flexural modulus | 2748 | 2777 | 2443 |
| MFR | 23.2 | 20.67 | 19.53 |
| HDT, 1.8 MPa | 72.8°C | 71.2°C | 70.2°C |
| HDT, 0.45 MPa | 87.0°C | 86.1°C | 84.8°C |
| Vicat | 93.9°C | 89.8°C | 87.5°C |
| L | 95.27 | 94.99 | 95.02 |
| a | -0.42 | -0.61 | -0.63 |
| b | 3.02 | 3.84 | 4.02 |
| Haze | 4.43 | 4.31 | 4.38 |
| Transmittance | 87.03 | 86.12 | 86.13 |
| YI | 5.45 | 6.81 | 7.12 |
Source terminology is preserved: the 20% formulation uses SAN, while the 25% and 28% source formulations use AS. Transparency is not assured and must be validated in the intended formulation.
Application test results are formulation-specific and should not be interpreted as guaranteed product specifications. Final grade selection and dosage should be validated in the customer’s own formulation and processing conditions.
