Syensqo’s bio-based registered trademark MTM 49-3 epoxy prepreg was incorporated in the rear brake duct wheel shields of Mercedes-AMG’s W16 race car, which competed in Azerbaijan Grand Prix in Baku in September, driven by British pilot George Russell. #Syensqo’s resin, which was launched in early 2024, includes 30% bio-based materials. A few weeks ago, the bio-based MTM 49-3 was awarded the Green Tech Award at the Race Tech World Motorsport Symposium. The #epoxyprepreg , which has been developed with 30% bio-sourced monomers, maintains the same mechanical strength, glass-transition temperature (190°C) and processability as its conventional counterpart. Compared with metals, it offers up to 40% weight savings. This is the first time that the team has used sustainable #carbonfibre composites on a technically performant component in race conditions. The new MTM 49-3 product variant incorporates bio-based content yet performs to the exacting standards of the motorsport industry,...

  Today's KNOWLEDGE Share 🔹 What Are Flow Lines in Injection Molding — and Why Should You Care? Flow lines are one of the most common (and frustrating) surface defects in plastic parts. They appear as: ➖ Wavy streaks ➖ Discoloration ➖ Directional lines following the melt flow These cosmetic issues don’t always affect function—but for customer-facing parts, they can ruin product aesthetics and perceived quality. 🔍 What causes flow lines? 🌡️ Material cooling too quickly in thin sections 🧊 Inconsistent mold temperatures 🌀 Flow hesitation around corners, holes, or sudden thickness changes 🐢 Injection speed too low or poor gate design 💡 How to reduce flow lines ✅ Optimize gate size & position ✅ Increase injection speed & pressure ✅ Improve mold temperature control ✅ Design smooth, even wall thickness transitions source : SCSplastic

  🔑 THE “BENT KEY PRINCIPLE” How a Tiny Mistake Inside Toyota’s Factory Created One of the Most Powerful Ideas in Modern Business In the early 1970s, Toyota’s assembly line stopped unexpectedly. Machines were silent. Workers froze. Supervisors rushed in. The entire line … capable of producing hundreds of cars a day…was shut down because of one tiny problem: A machine operator found a bent key inside a control panel. It was small. Barely noticeable. Harmless-looking. But the operator did something unusual: He pulled a cord above his station …the andon cord…which immediately stopped the entire factory. Managers panicked. Stopping the line cost thousands of dollars per minute. Engineers ran diagnostics. Maintenance teams checked panels. Finally, the confused supervisor asked: “Why did you stop production for something this small?” The operator held up the bent key and said: “If something this small is in the machine… something bigger is coming.” That one sentence changed the philosop...

Today's KNOWLEDGE Share You really understand how important mold temperature is in Injection Molding ? When molding semi-crystalline materials, a higher mold temperature will accelerate crystallization and possibly reduce (Yes, REDUCE) cycle time (see top right kinetic curve), while producing a stiffer part. When molding amorphous polymers, the degree of Physical Aging induced by a higher mold temperature will lead to a higher Yield Stress (left graph) and serious consequences on mechanical response. Creep performance and Impact will change by orders of magnitude, in opposite directions. Many erroneously interpret these effects as being due to residual stresses. source : Vito leo

In advanced chemical processing, material selection plays a crucial role in ensuring operational continuity, safety, and controlled process conditions. #Xenia expands its portfolio with a range of conductive thermoplastic solutions engineered to deliver consistent performance even when exposed to corrosive media, elevated temperatures, and stringent ATEX requirements. Conductive HDPE The combination of  #HDPE and carbon fibre results in a highly electrically conductive composite that offers an excellent balance between mechanical strength, electrical dissipation and chemical resistance. This material is particularly suited for components requiring mechanical performances and controlled electrical conductivity in industrial applications suchas piping systems and infrastructure,and insulation or protection  components. Conductive PP Xenia’s  #PP -based compounds are designed to enhance stiffness,...

Today's KNOWLEDGE Share The reality of Aramid fibres 0% biodegradable. That's the harsh reality of aramid fibres like Kevlar, Nomex, and Conex. These materials are engineered to be virtually indestructible (which makes them amazing at protecting lives), but nature has zero ability to break them down. Think about this: That old firefighting jacket sitting in a landfill isn't decomposing in a few years. It's not decomposing in a few decades. It's essentially a forever fibre, persisting in our environment indefinitely. The Environmental Double-Hit : Microfibre pollution: As aramid garments sit in landfills, they slowly fray into microscopic fibres that migrate into our soil and water systems. Just like microplastics, these aramid fragments persist indefinitely in our ecosystems. Toxic disposal: When incinerated, these flame-resistant fibres (designed NOT to burn) release dangerous gases including carbon monoxide and hydrogen cyanide. Add in the PFAS coatings used for ...
