Recyclable thermosets & thermoplastic recycling techniques to watch out for

The global market for recyclable thermoset polymers has attracted considerable attention in the past few years and the field has significantly advanced toward the development of new classes and varieties of thermosets with recycling capabilities, as per Transparency Market Research. Thermosets refer to the covalently cross-linked polymers that have superior resistance to a variety of environmental, mechanical, and thermal factors even at high temperatures and have excellent dimensional stability compared to conventional thermoplastics, which are also called thermoset polymers. Thermoset polymers are linear polymers that can be recycled and reprocessed using thermal energy owing to their easily accessible melting points. However, thermoplastics are not durable enough to be used in high performance applications, and are replaced by thermosets for applications that require materials that are indestructible or are virtually impossible to break down/melt or process using conventional thermoplastic recycling techniques. Consequently, discarding these thermosets in landfills than trying to recycle them has been the most preferred course of action of working around with thermosets. But developments in the global recyclable thermosets market are projected to bring a substantial change in this scenario. There has been rising awareness regarding environmental protection by avoiding the accumulation of unrecyclable polymers in landfills and unregulated places. Tax incentives and regulations have been introduced to encourage the development of recyclable thermosets. In response, researchers have designed some novel polymers that do not only have high performance features in line with conventional thermosets, but are also recyclable. The favorable research activities have substantially boosted the global market for recyclable thermosets. The changing regulatory scenario and the rising consumer awareness regarding the importance of reducing the use of fossil fuels are also crucial for the market’s growth and will significantly drive the market over the report’s forecast period. Some of the key recyclable thermosets available in the market currently are polyhexahydrotriazine (PHT), hemiaminal dynamic covalent networks (HDCNs), polyhexahydrotriazine added with carbon nanotubes, epoxy/polyepoxide resins, phenol formaldehyde, and unsaturated polyester resins (UPR). End use industries such as aerospace, electronics, and automobiles are projected to lead to an increased demand for recyclable thermosets to manufacture a variety of products and product parts. Asia Pacific is likely to be one of the largest consumers of recyclable thermosets over the report’s forecast period owing to the rising production of automobiles in the region. The rising population, coupled with strengthening economies, and rising disposable incomes in Asia Pacific have led to significant growth of the automobiles sector in the past few years, thereby enhancing growth prospects of several allied industries. This has also benefitted the market for recyclable thermosets in the past years and is expected to do so over the report’s forecast period. Demand for recyclable thermosets is also expected to increase in developed regional markets such as North America and Europe where stringent government regulations pertaining to material recycling are stimulating manufacturers to switch to recyclable varieties of core materials.
