Thermosoftening plastics can be easily molded and reshaped when heated, making them versatile for various applications. They are also generally cheaper to produce compared to thermosetting plastics. Additionally, thermosoftening plastics tend to have better impact resistance and toughness.
Thermosoftening is when the bonds between molecules in a plastic are weak so that the plastic can easily soften. Thermosetting is when the bonds are strong so that the plastic can only be softened once and when it is, that is the only time that you can shape it.
Polymers are plastic. Thermosoftening is hard when it is cold and flexible when it is warm. Thermosetting is flexible when cold and hard when hotThermosetting plastics are polymers that, once heated, melted and moulded, cannot be re-moulded as the bond between their molecules are too strong. Thermosoftening plastics are polymers which can be re-moulded many times as the bonds between the molecules are very weak. Thermosetting plastics can only be shaped once. Thermosoftening plastics can be shaped and re-shaped many times. :) hope this is helpful x
The strong force holds atomic nuclei together.

Thermosoftening plastics soften and can be given any shape when hot. The different types thermosoftening plastics are Polyethylene, Polystyrene, Poly Vinyl Chloride, ABS plastics.

Thermosoftening plastics are plastics that when heated, the polymers turn into a gooey kind of material which can then be put into a mould of whatever shape you wish the plastic to be. when it sets, you have your shaped plastic. thermosoftening plastics can be reheated and remoulded whereas thermosetting plastics cant be as the polymers for them, once moulded, cannot go gooey again because they have stronger chains between the polymers.
Thermosetting, these plastics are rigid, resistant to higher temperatures compared with thermoplastics and once set, a thermosetting plastic cannot be remoulded.
There are rtwo ypes of 'Plastic'. Thermosetting and Thermosoftening. Thermosetting if heated will just char (go black) Thermosoftening is heated will alter its shape. Different Thermosoftening plastics have different temperatures at which they soften. A Casual way to tell the difference is that thermosetting plastics are generally opaque, and thermosofteneing plastics a generally clear(see -through).
we can join plastics by burnig
Any plastic that if you put a flame to it , it will char/ burn/go black. NB A thermosoftening plastic is one , if heted, will just change shape. As a 'rule of thumb' opaque plastics are thermosetting; clear plastics are thermosoftening.
Wood glue holds boards together.
The cell membrane holds a cell together.
well all say the gravity holds everything together but i don't know what holds everything together
