The European Chemicals Agency’s ( #ECHA ) fourth report on the operation of #REACH and the Classification, Labelling and Packaging ( #CLP ) Regulation shows that these laws continue to play an important role in managing chemical safety in the EU. Helsinki, 1 June 2026 – The Report, based on data from 2021 to 2025, confirms that the implementation of REACH and CLP continues to progress towards its objectives, protecting health and the environment in Europe, while supporting innovation and competitiveness. While the earlier reports focused on REACH registration deadlines, the current reporting period shows a shift towards the systematic examination of substances already in the database. This includes screening and prioritisation of substances, generating targeted data and applying structured risk management measures. As a result, substances requiring #regulatory action can be identified and addressed more quickly, contributing to further reductions in emissions and lower exposure for c...

Trinseo has developed its first recyclable battery top cover based on thermoplastic #polycarbonateunidirectional (PC UD) tape, marking a significant advancement in lightweight, fire-resistant composite solutions for next-generation electric vehicle battery systems.  Developed at Trinseo's Global Innovation Center in Europe, the technology addresses critical design challenges facing OEMs and Tier-1 suppliers as they work to reduce vehicle weight, improve battery safety and build more circular manufacturing platforms. A New Approach to Battery Casing Design Built on Trinseo's flame-retardant PC UD tape technology, the battery top cover offers a compelling alternative to traditional metal- and thermoset-based designs. Available in thin-wall configurations of 1.0 mm and 1.5 mm, it supports industry efforts toward more circular vehicle platforms.  "This technology reflects Trinseo's capability to address key requirements identified by OEMs and Tier-1 suppliers, and when us...

Today's KNOWLEDGE Share : High Performance Polymers - Bio based Epoxy Resin

Image
Today's KNOWLEDGE Share High Performance Polymers - Bio based Epoxy Resin Epoxy thermosets are a class of high-performance polymers known for their excellent mechanical properties, chemical resistance, adhesive strength, and thermal stability. They are formed by the irreversible crosslinking reaction between an epoxy resin (containing at least two epoxide groups) and a curing agent (hardener). Biomass-derived epoxy thermosets specifically refer to those where either the epoxy monomer, the hardener, or both, are synthesized from biomass sources. This means that the fundamental building blocks of the polymer network originate from plants, agricultural waste, or other renewable biological feedstocks. The goal is to create materials with comparable or superior performance to their petroleum-derived counterparts, but with a significantly lower environmental footprint. Bio-based epoxy monomers are typically synthesized via the epoxidation of hydroxyl or amine compounds, or through the ox...

The rejection bin is only collecting failures - not preventing them. Behind recurring rejection bins, there are usually deeper issues like: ⚠ Unstable process parameters ⚠ Tool wear not monitored ⚠ Weak root cause analysis ⚠ Overdependence on final inspection ⚠ Small abnormalities ignored daily ๐Ÿ’ก Lean thinking teaches us: Quality should be BUILT into the process — not inspected after failure happens. A full rejection bin is not a sign of control. It is a signal that the process itself needs attention. World-class manufacturing focuses on: ✅ Eliminating root causes ✅ Process s...

Example: Polyethylene (PE) Repeating unit: –CH₂–CH₂– During polymerization, chain growth does not occur uniformly: Some polymer chains remain short Some grow to medium length Some become very long As a result, a single polymer sample contains a mixture of molecules with different chain lengths. For instance, one chain may contain 500 repeat units, another 5,000, and another 50,000, all chemically identical, yet with different molecular weights. Because polymers do not have identical molecules, their molecular weight cannot be represented by a single value. Instead, we use average molecular weights, such as: Number average molecular weight (Mn) Weight average molecular weight (Mw) Polydispersity Index (PDI = Mw / Mn) These averages help explain and predict: Chain length distri...
