What is thermosetting plastic? Answer only if you know spam answers will be reported....​

Answer 1

Answer:

A thermosetting polymer, resin, or plastic, often called a thermoset, is a polymer that is irreversibly hardened by curing from a soft solid or viscous liquid prepolymer or resin. Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst.

$\huge{\orange{\boxed{\fcolorbox{lime}{cadetblue}{\pink{ANSWER}}}}}$

☕ Thermosetting plastics are made up from long chains of molecules that are cross-linked. They have a very rigid structure.

☕ Once heated, thermosetting plastics can be moulded, shaped and pressed into shapes. Once set they cannot be reheated since they are permanently set.

NOTE ;-

• Thermosetting plastics are synthesized by condensation polymerization.

• Thermosetting Plastic is processed by compression moulding, reaction injection moulding.

• Thermosetting plastics have primary bonds between molecular chains and held together by strong cross-links.

• Thermosetting plastics have high melting points and tensile strength.

• Thermosetting Plastic is high in molecular weight.
