  As PET continues to expand across packaging, engineering plastics, films and consumer goods, large quantities of scrap, trimming waste, regrind and off-spec materials are generated during processing. Recycling these materials is no longer just a cost topic—it is a core strategy for sustainability and carbon reduction.   However, recycled or reprocessed PET faces several key challenges: • Chain scission after multiple heat histories → reduced IV and melt strength; &bu...

  Under global sustainability requirements, manufacturers face a key challenge: How to reduce carbon emissions while maintaining engineering-grade material performance? BAITONG provides a complete rPET-based modification solution that delivers both sustainability and high performance.   1. Challenges of Recycled PET (rPET) • High thermal sensitivity and IV loss due to multiple heat histories; • Reduced melt strength and poorer fiber/filler dispersion; • Large variations...

  Polyethylene terephthalate (PET) has long been the star material in packaging – from preforms and bottles to films and fibers. But when the target shifts to high-end engineering applications such as automotive parts, electrical connectors and appliance housings, conventional PET quickly reaches its limits:   • Instability in glass-fiber-reinforced systems, with fluctuating viscosity and mechanical properties; • Insufficient heat resistance, with HDT failing to meet h...

  Traditional physical recycling of PET faces unstable performance, downgraded use, IV loss, yellowing and insufficient heat resistance. rPET Physical Recycling: Turning Low-Value Waste into High-Value Material (BAITONG) BAITONG provides a molecular-engineering-based approach combining chain extension, anti-hydrolysis and functional add-on packages.   1. Key Challenges • Unstable IV and melt viscosity due to chain scission; • Unable to meet high-end applications such as bott...
