High Impact PMMA
High impact modified PMMA is produced by blending or graft copolymerizing elastomers (such as butadiene-based rubber, acrylic elastomers, or TPU) into the MMA matrix. Its core objective is to substantially improve impact resistance while maintaining PMMA's excellent transparency. Impact strength can be 3~10 times higher than unmodified PMMA, making it suitable for transparent structural components with safety requirements.
Technical Parameters
Parameter | Unit | Typical Value | Test Standard |
Density | g/cm³ | 1.15~1.20 | ISO 1183 |
Light Transmittance | % | 88~92 | ASTM D1003 |
Tensile Strength | MPa | 45~60 | ISO 527 |
Elongation at Break | % | 20~50 | ISO 527 |
Flexural Strength | MPa | 70~95 | ISO 178 |
Flexural Modulus | MPa | 2500~3000 | ISO 178 |
Izod Impact | kJ/m² | 8~25 | ISO 180 |
Charpy Impact | kJ/m² | 15~35 | ISO 179 |
HDT (1.8MPa) | ℃ | 85~95 | ISO 75 |
MFR (230℃/3.8kg) | g/10min | 2~12 | ISO 1133 |
Molding Shrinkage | % | 0.3~0.7 | ISO 294 |
Performance Characteristics
- Izod impact strength up to 15~30 kJ/m² (vs. ~2 kJ/m² for unmodified)
- Light transmittance slightly reduced, typically ≥88%; high-clarity formulations ≥90%
- Significantly improved toughness, resistant to shattering upon impact
- Blended with PC to balance transparency and impact resistance
- Suitable for automotive and rail transit components with safety regulations
Application:
- Automotive side windows, sunroofs, instrument panel covers
- Rail transit windows, transparent partitions
- Safety goggles, sports protective face shields
- Children's toys, appliance transparent housings (drop-resistant)
- Outdoor lighting fixture impact guards
