Question

Why thermosetting plastics cannot be remelted or reused ?​

Answer 1

Answer:

Thermosetting plastic molecules, on the other hand, form permanent chemical bonds or cross links with each other once heated. ... Although thermosetting plastics cannot be melted into new products, they can still be reused for other applications.

Explanation:

Thermoset plastics contain polymers that cross-link together during the curing process to form an irreversible chemical bond. ... Due to all these reasons Thermosetting polymers cannot be reshaped and reused.

Answer 2

Answer:

Thermosetting plastics cannot be remelted or reused because they only melt once, when they are first molded. They are cured with a heated mold (in injection molded thermosets), and solidify into their final
