History, as usually taught, focuses on big actions leading to big results — Caesar, Napoleon, the American and French Revolutions, etc. That is not always the case. Sometimes a small act can have oversized consequences. The most astonishing ones are those whose impact can be directly anticipated, but in an area far removed from its original intent. One hundred ten years ago (September 6, 1916, to be exact) in Memphis, TN, Clarence Saunders, someone who knew nothing about plastics, did something that drastically changed the future of our industry. The results were entirely predictable, but seeing that would have been challenging. Looking directly at the fledgling plastic industry would n...

NIR sorting systems identify polymers by recording how light scatters off a sample. Carbon black absorbs too much of that light, leaving detectors without a usable signal. The result: black plastics are routinely diverted to incineration or landfill, even when the underlying polymer would otherwise hold value. Raman spectroscopy offers a different approach. A small fraction of scattered light undergoes an energy shift that reveals molecular bond structure. Because Raman scattering occurs at a different wavelength than the incident laser, it can be distinguished and measured even in black and transparent plastics. Canon's TR-A100 applies this principle as a desktop instrument for material verification and purity checking — not ...

Cambium, a developer and manufacturer of advanced materials for defense and high-performance applications, will launch its breakthrough #lasereyeprotection (LEP) for commercial and private pilots at the upcoming Air Line Pilots Association (ALPA) 70th Air Safety Forum September 14–17, 2026 in Washington, D.C. Cambium selected pilot eyewear industry leader #FlyingEyes® , a professional-grade #eyewear brand founded and engineered by pilots. The bespoke eyewear will feature Flying Eyes frames fitted with Cambium #LEP lenses. This introduces a new standard in laser protection, allowing pilots to comfortably and seamlessly protect their eyes from disorienting green laser dazzle, while still easily reading their instrument panel with excellent visual acuity and color contrast, even during night flights. Laser strike incidents are a clear and present safety threat for pilots that can cause flash blindness and transient eyesight impairment after just one second of exposure. These so-called ...

Toray Industries, Inc., announced today that it has developed a materials design technology that enables the highly accurate and efficient selection of #thermosettingresin materials, used as matrix resins (see note 1), that achieve both recyclability (ease of decomposition and reuse) and mechanical performance in carbon fiber reinforced plastics (CFRP). The company will demonstrate the technology in materials development in deploying highly recyclable #CFRP across diverse applications, including #aircraft , #automotive , and general industrial uses. CFRP is increasingly being adopted as a structural material in applications such as aircraft and automobiles due to its lightweight nature and outstanding mechanical properties. At the same time, growing volumes of end-of-life CFRP are expected to drive increasing demand for recycling solutions. However, recycling thermosetting resins used in CFRP remains challenging. Technologies such as chemical recycling to recover raw materials and co...

In extrusion, transfer lines must balance two competing demands: minimizing pressure consumption while maintaining sufficient wall shear stress to prevent resin stagnation. A pipe that is too large reduces pressure drop but allows polymer to linger at the wall, degrading over time and appearing as gels or black specks in the final product. Key design parameters to address both concerns: - Target wall shear stress of 20 to 30 kPa to ensure continuous material renewal at the pipe wall - Design the transfer line as short as possible, since pressure consumption is directly proportional to pipe length - Use clam-shell type elbows with a bend radius at least five times the pipe diameter - ...
