electrical insulator, rubber and polystyrene isFISCHER ERNSTWASSMANSDORFF HANS
Many coffee travel mugs are made of hard plastic, either polystyrene or polycarbonate. Their insulative values are higher than glass, but lower than paper. Plastic travel mugs are tougher and thicker than either paper or Styrofoam cups. This not only improves the insulative ability of plastic mugs...
Ray McIntireinvented Styrofoam by accident. Polystyrene already existed and was a good insulator. However, it was too brittle. Ray was trying to develop a more flexible insulator. He combined styrene with isobutylene under pressure. When the pressure was released, he found that the isobutylene ev...
Styrofoam is non-biodegradable. It is also called polystyrene and is made from a petroleum by-product called Styrene. Styrene can be described as a toxic chemical and synthetic material, giving it a non-biodegradable nature.
A form of substance or material is known as an insulator that retard the transformation or flow of the electron (that denotes the electrical current), or heat from it is known as an insulator. Like, Styrofoam, Plastics, Glass, Rubber, and Fiberglass are some simple examples of...
Explain why polystyrene is much more readily oxidized by O_2 in the air than polyethylene is. Which H's in polystyrene are most easily abstracted and why? Explain why there is no change in the net electric charge of an isolated system. ...

6 First, the beads of polystyrene must be expanded to achieve the proper density. This process is known as pre-expansion, and involves heating the polystyrene either with steam (the most common method) or hot air (for high density foam, such as that used for a coffee cup); the heating ...
Plastics are created from single units, monomers, combined in a variety of ways. This process is called polymerisation. This is why plastics are also called polymers. And you often find the word poly used in the name i.e. polystyrene. ...
Expanded polystyrene is a plastic foam material that's commonly used for heat and sound insulation. Though expanded polystyrene is...
