Hydrogen bonding Modified starch hydroxyl groups anchor onto cellulose via hydrogen bonds. This improves surface strength and linting resistance. 2. Polymer dispersion Latex or styrene–acrylate particles distribute within the starch matrix, forming a co-continuous film during drying. 3. Hydrophobic orientation As water evaporates, hydrophobic side chains migrate toward the air interface. This lowers surface energy and enhances water resistance. So sizing is not only “adding starch.” It is controlling interfacial chemistry, film formation, and molecular orientation during drying. Performance starts at the nano-scale. source : Packaging Simplified #FiberMorphology #SurfaceChemistry

Today's KNOWLEDGE Share Masterbatches play a critical role in the performance engineering of thermoplastic compounds. From a technical perspective, a masterbatch is a concentrated system of pigments, fillers, or functional additives dispersed in a polymer carrier resin, designed to be incorporated into a base polymer during processing. Its main purpose is to ensure accurate dosing, improved dispersion, and better process consistency compared to direct raw additive incorporation. The technical value of a masterbatch is directly linked to three key factors: 1. Dispersion quality 2. Carrier resin compatibility 3. Additive stability during processing Thermoplastics would not exist without proper additivation! source: polimerizze Technology

Most manufacturing capacity problems don’t come from lack of machines or people - they come from misunderstanding which type of capacity you are planning against. This framework highlights three distinct capacity levels every leadership team should track: 🔹 Design Capacity - Theoretical maximum output under perfect conditions. Useful for engineering; dangerous for planning. 🔹 Effective Capacity - Realistic output after planned losses like changeovers, maintenance, quality checks, and training. This is the correct baseline for Lean planning. 🔹 Actual Capacity - What you truly deliver after unplanned losses, variability, and instability. Why this matters for leaders: • Planning with design capacity leads to overload and constant firefighting • Planning with effective capacity creates stable, achievable schedules • Measuring the gap between effective vs actual reveals hidden process instability • Closing that gap unlocks capacity without new capital investment • Stability + standard wo...

  Today's KNOWLEDGE Share 📣 What makes PTFE so unique — and, somehow, so “magic”? 📣 At its core, PTFE (Polytetrafluoroethylene) is built from a simple repeating unit: (–CF₂–CF₂–)ₙ. A carbon backbone fully surrounded by fluorine atoms creates one of the strongest molecular structures in polymer science. 🧪 This “fluorine shield” is the key to: ✅ Exceptional chemical resistance ✅ Extremely low coefficient of friction ✅ Wide operating temperature range (–200°C to +260°C) ✅ Outstanding electrical insulation ✅ Non-stick surface behavior 💡 The result? A material engineered at the molecular level to perform in the most demanding environments — from aerospace to advanced industrial applications. 🎯 At Resitape, we are a leading manufacturer of PTFE tapes and monofilaments, helping our customers make the “magic” happen across a wide range of applications. source : Alberto Evangelista

As a leading manufacturer of potting compounds, adhesives and sealants primarily used to protect sensitive electronics, #Wevo is expanding its presence in the Asia-Pacific region with a new production site in #Singapore . Located in the Tuas industrial area, the facility will serve as a key hub for supplying customers with locally manufactured #polyurethane systems that offer proven solutions across a wide range of industries, such as e-mobility and white goods, as well as the generation, distribution and storage of energy. With its new production site in Singapore, Wevo is responding to the growing demand for proven polyurethane-based potting compounds, adhesives and sealants, thus becoming a regional manufacturer for the Asia-Pacific market. “Our engagement in Singapore is a central component of our globalisation and growth strategy.

The cooling channels follow the shape of the part and stay at a constant distance from the cavity. This means that heat leaves faster and more evenly. This results in fewer hot spots and reduced warpage. These are some practical design rules we follow when looking at concepts for conformal cooling, especially for AM inserts (inserts made by additive manufacturing). Let D represent the diameter of the channel. → Keep it conformal: Try to keep the distance between the channel and the cavity on the surface as close to constant as possible. → Spacing (pitch): Start between the centerlines of two channels that are 3D to 4D apart. → Depth: A common starting window is 2D–3D from the centerline of the channel to the...

SVHC testing, on the other hand, specifically focuses on identifying high-risk substances within this system. Substances of Very High Concern (SVHC) are chemicals that can pose serious risks to human health or the environment. These include substances that are carcinogenic, mutagenic, or toxic to reproduction, as well as those that are persistent, bio-accumulative, and toxic (PBT), or very persistent and very bio-accumulative (vPvB). Such substances may be added to the REACH Candidate List fo...
