What is the real difference between low-value recycled PET and premium rPET sheet or film that can run smoothly, form cleanly, and deliver consistent quality? In many plants, the answer is not only raw material sourcing. It is what happens to molecular structure, melt behavior, and process stability Read More

High-strength PET compounds are not built by reinforcement alone. Many PET formulations look promising on paper, yet after drying, melt compounding, pelletizing, and molding, they lose stiffness, become brittle, or process less consistently than expected. The real bottleneck is often not the filler Read More

You deal with three main kinds of hydrolysis in polymers and plastics: acid, alkaline, and enzymatic. Hydrolysis breaks down these materials. This can make them last less time and work worse. Research shows that biodegradable plastics can lose strength fast or slow in the ocean. Read More

The most expensive yarn break is not always the one that stops the line. It is the one that reveals a deeper problem in the polymer itself: lower intrinsic viscosity, shorter molecular chains, weaker melt strength, and unstable spinnability. In PET filament and yarn production, those problems often Read More

Discover how PET chain extender agent helps flexible packaging films achieve better tear resistance, improved melt strength, stable gauge, fewer gels, and more consistent film quality in virgin and rPET film extrusion. Read More

Why do some PET bottles look acceptable at the start of production, then suddenly fail top-load checks, deform during capping, or show inconsistent dimensions from batch to batch? In many bottle plants, the real problem is not only mold design or blow pressure. The deeper issue is that the polymer e Read More

Your yarn can look fine, then breaks jump fast. Why does tenacity drop after one shift?A PET Chain Extender Agent can rebuild chain length in the melt. In this article, you’ll learn how it lifts spinnability and filament strength, plus drying, dosing windows, filtration, and simple QA checks. Read More

Biodegradable blends can look “green,” yet they can run messy. Why do PLA/PBAT/PBS lines still see haze, draw breaks, and wide MFI drift?A PET Chain Extender Agent can improve interface bonding and melt strength during reactive extrusion. In this article, you’ll learn dosing windows, key process knobs, and lean checks to scale stable film, sheet, or injection grades. Read More
