Because, it has no crosslinks therefore its molecules move more freely. On the other hand, some other polymers, such as Bakelite, are crosslinked and you cannot turn then into a liquid without breaking the covalent bond.
Tungsten is a metal with a particularly high melting point (which has made it suitable for use as a filament in incandescent bulbs); ionic compounds such as granite have high melting points. Ceramics have high melting points.
it has a low melting point
Chromium has a high melting point of 1,857°C (3,375°F) making it a refractory metal.
Uranium has a high melting point of 2,075°C (3,767°F), which is relatively high compared to many other metals. This high melting point makes uranium suitable for use in nuclear power reactors, where it needs to withstand high temperatures.

polythene bag has a higher melting point
One substance that has a high melting point is diamond.
it has a low melting point
All metals have different melting points but they are all high
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
Chromium has a high melting point of 1,857°C (3,375°F) making it a refractory metal.
Yes, it has a melting point of 1683 Kelvin.
No, this is a low melting point.
For example the melting point of acetylene -80,8 oC.
"High" is kind of subjective, but its melting point is 500oC, so I'd say that's pretty high.
