As PFAS regulation intensifies across jurisdictions, producers of film processing aids continue to advance substitute chemistries. Non-fluoropolymer PPAs have made significant strides, particularly with newer polyamide-based chemistries that operate effectively at lower dosages. But the transition is not straightforward. Key challenges with NF-PPAs include: -𝐒𝐜𝐫𝐞𝐰 𝐬𝐥𝐢𝐩𝐩𝐚𝐠𝐞 𝐚𝐧𝐝 𝐬𝐮𝐫𝐠𝐢𝐧𝐠 𝐟𝐫𝐨𝐦 𝐡𝐢𝐠𝐡 𝐏𝐏𝐀 𝐜𝐨𝐧𝐜𝐞𝐧𝐭𝐫𝐚𝐭𝐢𝐨𝐧𝐬 - 𝐏𝐫𝐢𝐧𝐭 𝐚𝐝𝐡𝐞𝐬𝐢𝐨𝐧 𝐟𝐚𝐢𝐥𝐮𝐫𝐞𝐬 𝐥𝐢𝐧𝐤𝐞𝐝 𝐭𝐨 𝐢𝐧𝐜𝐨𝐧𝐬𝐢𝐬𝐭𝐞𝐧𝐭 𝐝𝐨𝐬𝐢𝐧𝐠 - 𝐃𝐢𝐞 𝐥𝐢𝐩 𝐛𝐮𝐢𝐥𝐝𝐮𝐩 𝐝𝐫𝐢𝐯𝐞𝐧 𝐛𝐲 𝐨𝐱𝐢𝐝𝐢𝐳𝐞𝐝 𝐩𝐨𝐥𝐲𝐞𝐭𝐡𝐲𝐥𝐞𝐧𝐞 𝐝𝐞𝐠𝐫𝐚𝐝𝐚𝐭𝐢𝐨𝐧 - 𝐂𝐡𝐞𝐦𝐢𝐜𝐚𝐥 𝐚𝐧𝐭𝐚𝐠𝐨𝐧𝐢𝐬𝐦 𝐛𝐞𝐭𝐰𝐞𝐞𝐧 𝐍𝐅-𝐏𝐏𝐀𝐬 𝐚...

Mold components exposed to continuous material flow need appropriate steel selection and surface treatments. ➡️ Gate design The gate location and type can influence fiber orientation, filling balance, weld lines and the final mechanical performance of the part. ➡️ Runner system Runners...

These materials are not simply “expensive resins.” Some require very high molding temperatures. Some have poor flowability, making mold filling difficult. Others flow too easily, making even slight changes in conditions lead to flash. That is why we look beyond the material itself. We consider factors such as: • Flowability and shrinkage • Molding and mold temperatures • Venting and gate design • Mold material and wear • The process window for stable molding Many of the materials we have worked with started with a customer saying: “We want to use this material.” We have e...

These five laws have been around for decades, and they still explain most of what goes wrong at work: → Deadlines slip because time expands to fill the space (Parkinson). → Plans fail because we’re always too optimistic (Hofstadter). → Teams game KPIs instead of improving the work (Goodhart). → Great performers get promoted into roles they hate (Peter). → Colleagues seem out to get you when they’re really just busy (Hanlon). You can’t escape these laws. But once you see them, you can plan around them. Set tighter deadlines. Pad your estimates. Measure what matters, not what’s easy. Promote for the next role, not the last one. And assume good intent until proven otherwise. Which one do you see most often at work? ♻️ Repost to help someone in your network. source : Jen Blandos

This process causes transparent materials to become hazy, severely reducing visibility. This isn't just a minor inconvenience; its a major issue impacting sectors like the automotive, medical, and solar industries where it can lower a drivers field of vision, diminish surgical clarity, and decrease energy conversion efficiency. Fortunately, polymer science and nanotechnology are leading the charge with a more durable and cost-effective solution: antifogging coatings. source : Roberto YAÑEZ #AntifoggingCoatings #Innovation #MaterialScience #PolymerScience #Automotive #MedicalDevices #GreenhouseTechnology
