why thermoplastics are used in making buckets
Answers
Answer:
because thermoplastic is a long lasting plastic
Thermoplastics: Thermosetting and Thermosoftening Plastics
Manufacturing Technology / By Asheesh / Mechanical Engineering
Plastic has various unique properties compared to other materials, and it is being used to increase the quality of our daily life. We use plastic bags, nylon shirts, chairs, etc.; all are different types of plastic products. You can recognize by a touch that these products are not same. Some of them are very soft and some of them are significantly harder. We also use them as electrical and thermal insulators; for example plastic handle used in a pan and insulation around electrical fittings.
These different types of plastics are divided into two types, thermosetting and thermosoftening plastics. They have different properties and application areas.
Thermosoftening Plastics or Thermoplastics
The intermolecular forces between the polymer chains of thermoplastics are very weak; due to this, they can be remolded into new

shapes easily. They can be softened between the temperature 65ºC and 200ºC (149°F to 392°F) and once set, can be returned to their plastic state by reheating. The methods that are used to mould them are injection molding, extrusion, vacuum forming, compression molding, and rotational molding.
