Waste polymer recycling can be carried out by four approaches in accordance with ISO 15270, namely: Primary recycling refers to the recycling of the scrap material of controlled history. What is the Difference between Thermoset and Thermoplastic? Thermosetting plastics and thermoplastics are both polymers, but they behave differently when exposed to heat. They are similar to PA6 and PA66 in many respects but with much lower water absorption. Thermoplastics are unique in that their polymer bonds allow them to be heated and remolded indefinitely, making them highly recyclable, while thermosets feature permanent chemical bonds that harden after a single. Medical Devices. The intricate world of polymers is a realm ruled by two dominant categories: thermosets and thermoplastics. The primary difference between the two is that Thermoset is a material that strengthens when heated, but cannot be remolded or heated after the initial forming, while thermoplastics can be reheated, remolded, and cooled as necessary without causing any chemical changes.
