High-Impact Polystyrene (HIPS)

High-Impact Polystyrene (HIPS) is a versatile, impact-resistant polymer made from styrene monomer. It is known for its excellent processability and ability to provide a combination of strength and flexibility. HIPS is widely used in various industries due to its high resistance to moisture absorption and good electrical insulation properties. However, it is sensitive to high temperatures and should not be used above 85°C. Its applications are vast, including food packaging, household appliances, and electronic components.

Technical Characteristics:

• Molecular formula: (C8H8) n
• Density (gr/cm³): 1.04 – 1.06
• Melting point: 240°C
• Melt flow index at 200°C and 5 kg load: 4.5 (gr/10min)
• Tensile strength: 23 (MPa)
• Vicat softening temperature: 97°C
• Appearance: Transparent, rigid, and glossy

Applications:

• Packaging for food, medicine, cosmetics, industrial, and horticultural products
• Toys
• Household appliances
• Plastic containers
• Electrical components
• Medical equipment
• Packaging film for various products

Environmental Impact of HIPS

HIPS, like many plastics, contributes to environmental pollution as it is non-biodegradable and can persist in the environment for centuries. Its production depends on fossil fuels, leading to greenhouse gas emissions. While HIPS is technically recyclable, contamination and limited recycling facilities mean that much of it ends up in landfills or is incinerated, releasing harmful pollutants. Efforts to reduce HIPS waste focus on improved recycling methods and reducing plastic usage in various sectors.

Safety Measures and Regulations for Handling HIPS
HIPS is generally safe to handle, but, like all plastics, it can emit fumes if heated improperly. Adequate ventilation, protective equipment, and careful control of temperatures are necessary to ensure safe handling. Compliance with safety regulations and industry standards is crucial to prevent health hazards and environmental damage. Standards such as those from OSHA and EPA help mitigate risks related to the handling and disposal of HIPS.

Packing
HIPS is typically available in 25 kg bags.
