Polymers can be divided into which two sections?

Polymers can indeed be divided into categories based on their properties and behaviors when subjected to heat, which is captured in the classification of thermoforming and thermosetting.

Thermoforming polymers, such as PVC and LDPE, can be repeatedly softened upon heating, allowing them to be reshaped multiple times. This property makes them versatile for various applications in manufacturing processes, including packaging and various consumer products.

Thermosetting polymers, on the other hand, undergo a chemical change when cured, which means they cannot be remolded or reshaped once set. Examples include epoxy resins and phenolic resins, which are valued for their strength and heat resistance.

This distinction is fundamental in understanding how different types of polymers can be processed and utilized in product design, influencing decisions regarding material selection based on the intended application and performance needs.
