Do Thermoplastics Have Cross Links?

When classified by chemical structure, there are two generally recognized classes of plastic materials: Thermosets, having cross-linked molecular chains, and Thermoplastics, which are made up of linear molecular chains. ... The second is done by the molder, who controls final cross-linking.

Are thermosetting polymer cross-links?

Thermosetting polymers are highly cross-linked polymers and cannot be recycled or reprocessed.

Can thermoplastics be reprocessed?

Thermoplastics are easily recyclable, compared to thermosets, because the polymer chain does not degrade when melted down. ... Recycling or reforming a thermoplastic is like chipping out the mortar and re-laying the bricks.
