polystyrene (GPPS) is a transparent, hard, and brittle polymer that is used in various industries due to its easy processability. It has high transparency, good electrical insulation, and moderate chemical resistance, but is brittle against impact and is soluble in organic solvents. Its important applications include the production of transparent disposable containers, electronic components, laboratory equipment, and decorative products such as transparent talc. It is also commonly combined with HIPS (high-impact polystyrene) to increase impact resistance.
Technical Characteristics
| Molecular formula | (C8H8) n |
| Density (gr/cm3) | 0.96 – 1.04 |
| Melting point | 240(°C) |
| Melt flow index at 200°C and 5 kg load | 7 (gr/10min) |
| Tensile strength | 52(MPa) |
| Vicat softening temperature | 100(°C) |
| Appearance | Transparent, colorless and hard |
Applications
- Food packing
• Extrusion foam packaging
• Plastic compound manufacturing
• Production of household appliances
• Combination with SBS for impact-resistant applications in XPS insulation
• Medical laboratory utensils and containers
Environmental Impact of GPPS
GPPS has a notable environmental impact due to its non-biodegradability and contribution to plastic pollution. Its production relies on fossil fuels, leading to greenhouse gas emissions. GPPS waste persists in the environment for centuries, polluting land and oceans, with wildlife at risk from plastic ingestion. While recycling is possible, contamination and limited facilities result in most GPPS waste ending up in landfills or being incinerated, releasing harmful emissions.
Safety Measures and Regulations for Handling GPPS
Although GPPS is generally safe, heating or processing it can release styrene, a hazardous substance. Proper ventilation, protective gear, and controlled temperatures are essential for safe handling. Regulations vary by region, with agencies enforcing recycling and waste management guidelines. Compliance with safety standards, such as those set by OSHA and EPA, helps reduce environmental and health risks.
