STYRENE & POLYSTYRENE

What is one key property of polystyrene that makes it useful in the production of packaging materials?

• • High resistance to high temperatures

• High electrical conductivity

• • Low thermal conductivity and brittleness

• High water solubility

Which of the following products is most commonly made using polystyrene?

• • Automobile tires

• • Disposable cutlery and food containers

• • Electrical wiring

• Solar panels

When working with styrene, which safety measure is essential to minimize health risks?

• • Storing styrene in an open, non-ventilated area

• • Wearing protective gloves, goggles, and ensuring adequate ventilation

• • Handling styrene near open flames for faster evaporation

• • Ignoring respiratory protection, as styrene does not release hazardous fumes

What is the primary use of styrene in the manufacturing industry?

• • As a monomer for producing polystyrene and other polymers

• As a lubricant

• • As a solvent for dyes

• • In the production of medicines

What is the main environmental concern associated with styrene and polystyrene?

• • They are highly toxic to aquatic life

• • Styrene is non-biodegradable and can cause pollution

• • They are radioactive

• • They contribute to global warming

What material was used in the concentrator to adsorb VOCs and prevent styrene polymerization?

• Activated Carbon

• Silicon Oxide

• Zeolite

• Magnesium Oxide

Which are the following below is not the forest waste biomass used in the production of styrene?

• Fresh leaves

• Carboxymethylcellulose

• Wood

• Soft bark

Temperature changes do not affect storage emissions of styrene.

• True

• False

Why was the emission concentrator coupled with a catalytic oxidizer more cost-effective than RTOs or bio-filtration systems?

• It required less maintenance

• It used water as a scrubbing medium

• It reduced process air needing treatment by a factor of 10

• It destroyed VOCs without heat

Low-styrene gel coats and resins can help reduce styrene emissions

• True

• False
