𝐒𝐮𝐧𝐝𝐚𝐲'𝐬 𝐓𝐇𝐎𝐔𝐆𝐇𝐓𝐅𝐔𝐋 𝐏𝐨𝐬𝐭 𝐏𝐨𝐥𝐲𝐦𝐞𝐫 𝐂𝐨𝐧𝐟𝐨𝐫𝐦𝐚𝐭𝐢𝐨𝐧 𝐚𝐧𝐝 𝐂𝐨𝐧𝐟𝐢𝐠𝐮𝐫𝐚𝐭𝐢𝐨𝐧 To understand why polymeric materials behave the way they do, from stretchy rubber to rigid plastics, it is essential to understand their structure at the molecular level. Two critical concepts describe this structure: configuration and conformation. While both terms describe how atoms are arranged in space along a polymer chain, they are fundamentally different in the amount of energy needed to change that arrangement and the speed at which those changes occur.  #Configuration is fixed chemically and requires breaking bonds to change, whereas  #conformation is flexible and changes rapidly due to thermal energy. Understanding this distinction is key to designing materials with specific properties. This infographic provides a clear comparison of these concepts, illustrating how these molecular details determine the final behavior of the polymer. source : Rob...

That can help set realistic expectations for production. Consider: How can a minority of microscopic clay particles, through their surface charges and enormous collective surface area, bind a mass of other nonplastic mineral particles into something that can be shaped? Using just water as the glue? How is it even possible that a handle can become rigid during drying while the mug body continues to shrink and dry, yet no crack occurs? How can a clay-containing glaze powder, which must shrink on drying, stick to a smooth bisque surface and not crack off? Temperature gradients are inevitable, meaning different parts of the mug are not passing through the same stages of quartz inversion, yet it does not dunt. How can a clay body soften as if it vitrifies in the kiln yet still sta...

This temporary mixture of two immiscible liquids will naturally separate over time to reach a state of minimum free energy. 👉 The key factors behind this instability are the increase in surface area during emulsification and inherent interfacial tension between the immiscible phases. ◾The basis of thermodynamic instability: 🔹The thermodynamic stability of an emulsion is determined by the change in Gibbs free energy (∆G). 🔹For a system to be thermodynamically stable, the overall change in Gibbs free energy must be negative (∆G<0) and spontaneous. 🔹The equation for Gibbs free energy is expressed as: ∆G = ∆H - T∆S where: ∆H is the change in enthalpy. T is the temperature. ∆S is the change in entropy. 🔸For an emulsion, the change in Gibbs ...

DAHER's Highly Loaded Thermoplastic Wing Rib demonstrator is the product of deliberate R&D infrastructure, not a one-off experiment. Developed at the company's Shap'in TechCenter in Saint-Aignan-de-Grandlieu, France, the rib combines carbon fiber-reinforced thermoplastics with two patented processes: - Direct stamping eliminates the consolidation step between layup and stamping, reducing cycle time and cost - Infrared welding joins the two L-shaped halves into a T-shape without a single rivet Compared to bolted aluminum assemblies, the result is 22% weight reduction, 15% lower assembly cost, a 25% shorter production cycle, and full recyclability — a combination that earned a 2026 JEC Innovation Award. The Shap'in TechCenter was built to co-locate design, materials, and ...

Exel Composites and Suzlon Energy Limited are expanding their collaboration with a new multi-year supply agreement for pultruded carbon fiber planks used in wind turbine blade spar caps. At the time of signing, the parties estimated that the potential value of future deliveries under the agreement will exceed EUR 100 million through March 2029. Under the agreement, Exel Composites’ India-based joint venture Kineco Exel Composites India (KECI) will supply an agreed share of Suzlon’s requirements for the products covered by the agreement. The final value and timing of deliveries may vary depending on Suzlon’s actual production requirements and the resulting order volumes. Building on an established partnership The agreement builds on a collaboration that began in 2024 and supports the continued ramp-up of Exel’s manufacturing operations in India. Exel and Suzlon began working together in 2024 under a two-year supply agreement. The collaboration led to the approximately EUR 10 million pur...
