Polystyrene
POLYSTYRENE CRYSTAL
FORMULA/ CHEMICAL COMPOSITION
MATERIAL DESCRIPTION
All polystyrenes have excellent process ability and a low heat capacity value leading to process energy reduction. With its high stiffness and low density, all articles made from polystyrene have excellent strength-to-weight ratio offering many environmental benefits, such a reduction of weight, nonrenewable resource savings, transportation costs and carbon footprint.
EXTRACTION PROCESS
Methanol extraction out of polystyrene at 100 ‘C and requires 6 hours
BASIC PROPERTIES
| COMPRESSIVE STRENGTH (N/M2) 10-60 PSI 69.000- 413.000 |
| TENSILE STRENGTH (N/M2) 46 x10^6 – 60×10^6 |
| STIFFNESS (N/M2) 3000 x10^6 – 3600 x10^6 |
| DENSITY (KG/M3) 16 – 640 |
| CARBON FOOTPRINT (AVERAGE, KGCO2E/KG) 1.87 |
| RECYCLABLE YES |
| LASER SMALL (According to thickness) YES |
| LASER MILLING YES |
| 3D PRINTING (If mixed with LIMONENE Solvent) YES |
ADVANTAGE IN THE CONTEXT OF DIGITAL FABRICATION:
It is a very inexpensive resin per unit weight, can be used by all machines, recyclable.
