VOC/particles
| Property | Value / Note |
|---|---|
| Composition | Methacrylate shell with rubbery butadiene core and styrene; engineered terpolymer |
| Physical state | Solid pellets/powder; dust may become airborne during conveying/mixing |
| Processing | Extrusion/molding temperatures typically 180–240 °C (grade-dependent) |
| Fume constituents | Residual monomers (styrene, methyl methacrylate) + thermal decomposition products |
| Reactivity | Combustible; dust may explode (Kst St-1 typical for polymers); avoid ignition sources |
| Typical uses | Impact-modification of rigid PVC, transparent housings, films, profiles |
