why not !!
Why is polystyrene brittle?
Unfilled polystyrene is also known as crystal polystyrene (PS) or general purpose polystyrene (GPPS). However, since crystal polystyrene is brittle, other polymers are added to polystyrene to improve its strength, and copolymers are formed as a result. One such copolymer is high impact polystyrene (HIPS), which is produced by adding polybutadiene rubber to polystyrene during the polymerization process. HIPS is tougher and has a greater impact strength than unfilled polystyrene. There are different types of polystyrene. Extruded polystyrene (XPS) is one form of the polymer that has high tensile strength, with good elasticity. It is commonly known as Styrofoam™. The other common form of polystyrene is expanded polystyrene (EPS). Both EPS and XPS are made from similar materials but there are difference between the two. XPS has a higher density as compared to EPS, due to the absence of air passages between its cells. The higher density makes XPS more rigid and strong. Also, XPS is waterproof and is an effective thermal insulator. Read more in the related link.
What are dangers of polystyrene beads?
Polystyrene is today difficult to be recycled.
Why polystyrene is homopolymer?
Polystyrene is formed from only one monomer - styrene.
Is styrofoam the same as polystyrene?
They are made from the same polymer, polystyrene. Usually polystyrene is clear, hard and rigid, for example in CD cases. However, styrofoam is created by blowing air through liquid polystyrene. The bubbles are locked in the polystyrene as it solidifies, giving the syrofoam used in packaging and cups. The reason it is compressible is because the air is compressed, rather than the hard, rigid polystyrene itself.
Why should you use polystyrene and thermalplastic to make ear defenders?

Why is plastic a good idea for ear defenders?
plastic is a good idea for the final layer of ear defenders because it is tough and effective. it's also relitavely cheap, when do not see plastic used on head/earphones, it helps block out sounds. BOOM
Who needs to wear ear defenders?
The people who wear ear defenders are the people who live or work in noisy environments, the Ear defenders protect them from loud noises, For example a builder might wear ear defenders to prtect his ears from the loud noise of the construction site. The noise may damage, His/Her ears.
Why do people wear ear defenders?
people wear eardefenders because some peoples ears get really cold and they can get an ear infection that's why people wear ear defenders
What part of the ear is protected when wearing ear defenders?
Well, ear defenders will sit over your whole ear protecting all of it. But the part that's important to protect is the inner ear, that's where the actual hearing takes place.
Who wears ear defenders?
work men
