Teijin Limited announced today that it has developed a thermosetting, long carbon fiber-reinforced plastic (CFRP) that combines a heat-activated self-healing function with high recyclability, while offering mechanical properties equivalent to those of conventional CFRPs. Damaged areas of the new material can be repaired by being heated for a short time at a specified temperature, enabling repair rather than replacement and thereby helping to extend product lifetime and reduce resource consumption. Further, Teijin’s CFRP enables recycling through a simple chemical decomposition process, thereby contributing to circularity. A wide range of applications can benefit from the strength and light weight of this CFRP material, including aircraft, automobiles and sporting goods. Sustainability requirements are driving material development There is growing demand for products that help to reduce greenhouse gas (GHG) emissions throughout the entire life cycle. However, CFRPs, made by impregnating...

Dyneema®, owned by Avient Corporation, an innovator of materials solutions, will exhibit at the SMM trade fair in Hamburg from September 1–4, 2026, sharing its portfolio of advanced fiber grades used in high-performance mooring lines and offshore marine applications. At this year’s event, Dyneema® will introduce its latest fiber grade to the maritime industry: Dyneema® SK80 fiber. Engineered at the polymer level, it delivers at least twice the durability and fatigue resistance of Dyneema® SK78 fiber in demanding mooring applications. As a result, Dyneema® SK80 fiber provides even greater reliability in the most challenging marine conditions.  Built on a strong legacy of fiber innovation For more than 20 years, Dyneema® SK78 fiber has been used in the core of the strongest, lightest, and most durable HMPE mooring ropes on the market. Now, following market feedback and years of rigorous in-house research, development, and testing, Dyneema® SK80 fiber builds on the proven performance ...

Mixed plastic waste is nearly impossible to recycle, with billions of tons choking landfills and incinerators worldwide. Now scientists in California and South Korea have developed a unique, experimental method to manage this problematic stream. It’s designed to deliver another advantage: converting the trash into clean hydrogen while trapping carbon before it’s released to the air. Mixed plastic waste is nearly impossible to recycle, with billions of tons choking landfills and incinerators worldwide. Now scientists in California and South Korea have developed a unique, experimental method to manage this problematic stream. It’s designed to deliver another advantage: converting the trash into clean hydrogen while trapping carbon before it’s released to the air. Study co-author Woo-Jae Kim, a professor at Ewha Womans University, Korea, believes the thermal technology could achieve a $4-per-kilogram (kg) hydrogen cost. This would put it in line with North American subsidized rates for gr...

Syensqo announced today that an Administrative Law Judge (ALJ) at the U.S. International Trade Commission (USITC) has issued an Initial Determination in a Section 337 investigation involving Syensqo’s #polyvinylidenefluoride ( #PVDF ) technology for lithium-ion batteries. The Initial Determination is subject to review by the full Commission and the USITC and is subject to appeal.  The ALJ found that the PVDF products at issue in the investigation infringe Syensqo Specialty Polymers USA, LLC’s asserted patent. The Initial Determination also affirmed the validity of Syensqo’s patent and concluded that Syensqo’s investments and activities in the United States satisfy the domestic-industry requirement under Section 337.    The respondents concerned by the Initial Determination are Hubei Fluorine New Materials Co. Ltd., Zhejiang Fluorine Chemical New Material Co. Ltd., Sinochem Lantian Co. Ltd., and Zhejiang Juhua Co. Ltd.  Syensqo’s Solef® PVDF portfolio includes materi...

The Pareto Chart is one of the 7 Basic Quality Tools that helps identify the few causes responsible for the majority of problems. 📈 🔍 What is a Pareto Chart? A bar chart that ranks problems from highest to lowest frequency, combined with a cumulative percentage line. 🎯 Why use Pareto Analysis? ✅ Identify the most critical defects or issues ✅ Prioritize improvement efforts ✅ Focus resources where they create maximum impact ✅ Reduce defects faster and more effectively ✅ Improve quality, productivity, and customer satisfaction 📌 Example Defect Analysis 🔴 Blow Hole – 250 🟠 Unfill – 200 🟡 Carbon – 110 🟢 Soldering – 90 🔵 Catching – 50 🟣 Dent – 30 ⚫ Blister – 20 ⚪ Crack – 10 📈 In this example, the first few defect types contribute to nearly 80% of total defects. Fixing these first delivers the biggest improvement. 💡 Key T...
