Thermoplastics, such as polyethylene and polypropylene, can be melted and molded because they can be reshaped multiple times when heated.
Thermoplastic plastics melt when heated and therefore can be easily molded and recycled. In comparison, Thermoset plastics utilize a chemical reaction to cure and irreversibly set.
Thermoplastics are lightweight, flexible, and have good impact resistance. They can be easily molded and reshaped when exposed to heat, making them versatile for various applications. Additionally, thermoplastics are recyclable and environmentally friendly.
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.
Plastics are lightweight, durable, and versatile materials that can be molded into various shapes and forms. They are also resistant to water and chemicals, making them suitable for a wide range of applications. Additionally, plastics are cost-effective to produce and can be easily recycled.
The objective of plastics is to serve as versatile, durable, lightweight materials for a wide range of applications, including packaging, construction, transportation, and consumer goods. Plastics provide cost-effective solutions and can be molded into various shapes and forms to meet specific requirements.

Plastics are cheap and can be molded into many things. One drawback to using plastics is they harm the environment.
Molded plastics is a huge business. Some examples of molded plastics include piping that carries water and sewage when constructing houses, housing for electrical goods such as DVD players and television sets and even parts for aeroplanes making them more fuel efficient.
thermoplastics can be melted / heated up and re-moulded into a completely new shape. usually once re-heated they will re-take their original shape. Thermosetting Plastics cannot be melted down or re-shaped once they have originally set.
Thermoplastics are the type of plastics that can be melted and re-molded using thinners. Common examples include polyvinyl chloride (PVC) and polystyrene, which can be softened with appropriate solvents, allowing them to be reshaped. This property makes thermoplastics versatile for various applications, including recycling and crafting. However, the specific type of thinner needed can vary depending on the plastic being used.

Polymers are large molecules made up of repeating units, while plastics are a type of polymer that can be molded into various shapes. Not all polymers are plastics, but all plastics are polymers. Plastics are a subset of polymers that have additional properties, such as being lightweight, durable, and easily molded.
Modern plastic is derived from petrochemicals, which are obtained from fossil fuels such as crude oil and natural gas. These raw materials are chemically processed to create various types of plastics, which are then molded or shaped into different products.
The blacksmith melted the steel down until it could be molded.
Thermoplastic plastics melt when heated and therefore can be easily molded and recycled. In comparison, Thermoset plastics utilize a chemical reaction to cure and irreversibly set.
They are melted down then used in other plastics
Assuming this refers to transparent physical boxes, the boxes are most commonly made of plastics such as polypropylene. The plastics are molded by machine into the required shape.
