Additionally, automotive parts and devices made from TPE make vehicles lighter and more fuel efficient. ; Thermoplastics – Thermoplastics refers to a type of plastic made from polymer resins that become homogenized when heated. For radical reactions (23, 24)—for example, inter-chain recombination reactions —a yield as low as a 10th of a percent can block an extruder ( 26). As mentioned earlier, thermoplastics can undergo melting and hardening cycles through heating, and all three recycling methods (mechanical, chemical, and incineration) are used for their recycling. Thermosets usually are three-dimensional networked polymers in which there is a high degree of cross-linking between polymer chains. Cost-effective: Thermoplastics are often cheaper than thermosetting plastics due to their ease of processing and recyclability. . The process of thermoforming. [Br. 6.
