Against the backdrop of global "dual carbon" goals and the full implementation of Extended Producer Responsibility (EPR) policies, TPU (Thermoplastic Polyurethane)—a critical material in footwear, automotive interiors, and electronic coating sectors—has seen its recycling and pelletizing demand surge at an annual rate of 22.3% (predicted by BloombergNEF). Traditional TPU recycling struggles to meet high-end market requirements due to performance degradation and complex processes. However, three frontier technologies—molecular-level chemical recycling, intelligent physical sorting, and high-performance modification integration—are comprehensively reshaping the TPU recycling and pelletizing industry landscape. As a professional manufacturer with over 10 years of experience in plastic recycling equipment, Weiquan Machinery translates these cutting-edge technologies into actionable production solutions through customized equipment R&D and full-chain service capabilities, helping global customers achieve the profit goal of "converting waste into high-value pellets."
I. Cutting-Edge TPU Recycling & Pelletizing Technologies: Breaking Through Performance and Efficiency Bottlenecks
Today, TPU recycling and pelletizing have evolved from "simple melt pelletizing" to a new stage of "precision recycling + performance enhancement." Three core technologies have become the key to industry competition:
1. Chemical Molecular-Level Recycling: Unlocking the "Performance Code" for High-End Applications
Chemical recycling decomposes TPU waste into monomers such as polyols and amines through alcoholysis, hydrolysis, and other processes, then resynthesizes high-purity TPU pellets. It is the only technical path that can achieve "recycled materials matching the performance of virgin materials." Its core breakthroughs lie in improved reaction efficiency and energy consumption control:
Microwave-Assisted Alcoholysis Technology: As adopted by Shenzhen Lvsu Technology, it achieves a one-pass TPU conversion rate of 92.5% at 180℃ under normal pressure. Compared with traditional heating methods, energy consumption is reduced by 35%, the tensile strength of recycled materials reaches over 95% of virgin materials, and the elongation at break stabilizes at 85%~92%. It has passed GRS certification and entered the electronic coating material supply chains of Huawei and OPPO.
Low-Temperature Depolymerization Process: Independently developed by Wanhua Chemical, this technology lowers the reaction temperature to 160℃. Special catalysts reduce molecular chain breakage, the VOC emission of recycled materials is less than 50μg/g (meeting the automotive interior standards of Volkswagen and BYD), and the daily output of a single production line is increased to 12 tons.
Addressing the needs of chemical recycling and pelletizing, Weiquan Machinery has custom-developed an integrated TPU depolymerization-pelletizing linkage line: equipped with an AI temperature control system for special reactors (real-time temperature adjustment ±1℃), an online viscosity monitoring module, and a closed-loop monomer purification device. This ensures the depolymerization reaction time is shortened to less than 2.5 hours while meeting CE and ISO certification standards. Currently, this production line has been exported to Germany, Southeast Asia, and other regions, serving TPU recycling projects supporting automotive OEMs.
2. Intelligent Physical Sorting: Laying the Foundation for High-Purity Recycled Materials
High-purity raw materials are the premise of high-quality TPU recycling. Traditional manual sorting is inefficient and error-prone, while intelligent physical sorting technology achieves precise separation of TPU waste from impurities through multi-dimensional identification and classification:
Near-Infrared (NIR) + AI Image Recognition Sorting: This technology integrates NIR spectral analysis and AI visual algorithms to identify TPU materials with different melting points, colors, and impurity contents at a sorting speed of 600 pieces per minute. The impurity removal rate exceeds 99.2%, effectively separating TPU from mixed plastics such as PVC and PE.
Electrostatic Separation for Micro-Impurities: Targeting tiny metal particles and inorganic contaminants in TPU waste, electrostatic separation technology uses differences in electrical conductivity to remove impurities as small as 0.1mm, ensuring the purity of recycled materials meets food contact and electronic grade standards.
Weiquan Machinery’s TPU physical recycling line is equipped with a customized intelligent sorting module that can be adjusted according to the type of TPU waste (such as post-industrial scrap, post-consumer footwear waste, or electronic coating leftovers). The line integrates crushing, washing, drying, and sorting processes into one, reducing intermediate transportation links and improving production efficiency by 40% compared with traditional discrete equipment. With its stable performance, the line has been widely used in recycling projects in Europe and North America.
3. Integration of High-Performance Modification: Enhancing the Added Value of Recycled Pellets
To expand the application scope of recycled TPU pellets, high-performance modification technology has become a key link in the industry. By adding functional additives and optimizing the extrusion process, the performance of recycled materials is enhanced or upgraded:
Reinforcement and Toughening Modification: Adding nano-calcium carbonate or elastomer modifiers to recycled TPU improves its wear resistance and impact resistance. The modified recycled pellets can be used in automotive door panels and shoe sole materials, with performance reaching 90% of virgin materials.
Flame Retardant and Antioxidant Modification: Through the addition of environmentally friendly flame retardants and antioxidant masterbatches, the recycled TPU meets the UL94 V-0 flame retardant standard and has a service life extended by 3~5 years, making it suitable for electronic device casings and wire and cable sheaths.
Weiquan Machinery’s TPU recycling and pelletizing line is designed with a modular modification unit that allows customers to flexibly configure additive feeding systems according to product requirements. The line is matched with a twin-screw extruder with precise temperature control and uniform mixing, ensuring the modified recycled pellets have stable performance and consistent quality. It has obtained relevant international certifications and is trusted by customers in high-end application fields.
