That’s because people don’t just pay for what you sell - they pay for where they find you. If you’re not happy with what you’re making,  stop blaming the market. Start looking at: ↳ Where you’re playing. ↳ Who you’re selling to. ↳ How you’re positioning yourself. I learnt this the hard way. When I launched my communications and PR training company in the UK, I underpriced myself thinking I’d be booked solid. Instead, I was ignored by the very corporates and government clients I wanted to work with. When I raised my rates to match the market’s top tier, I was booked months in advance. Same service. Same expertise. Different perceived value. Here’s the takeaway: 1/ Everyone has an audience. 2/ M...

The Company has commenced sample work for these new products. Because it is lightweight yet offers high strength and stiffness, carbon fiber reinforced plastic (CFRP) is used in a broad spectrum of applications, from sports and leisure to mobility and industry. In terms of physical properties, damage to CFRP often originates not in the carbon fiber itself, but in the resin that supports the carbon fibers or at the inter...

A mix of recycling technologies is necessary to ensure that a broad variety of plastics can be recycled. Unlike high-volume commodity plastics such as the polyolefins used in packaging, specialty plastics often require recycling technologies tailored to their specific properties and applications. This applies, for example, to compounded polyolefins, polyurethanes and polyamides. These materials are designed for demanding uses, such as automotive applications, where standard plastics often do not provide the required performance. This is the subject of a recent article by BASF researchers in the prestigious U.S. academic journal Accounts of Materials Research. Achieving circularity for plastics from heterogeneous waste streams requires two things: scalable sorting processes and the right mix of recycling technologies. The suitable approach depends on the material itself as well as on the composition of the waste stream. “There is not one single standard technology for recycling engineer...

  𝐓𝐨𝐝𝐚𝐲'𝐬 𝐊𝐍𝐎𝐖𝐋𝐄𝐃𝐆𝐄 𝐒𝐡𝐚𝐫𝐞 🔬 𝐇𝐲𝐝𝐫𝐨𝐠𝐞𝐧 𝐯𝐬 𝐏𝐞𝐫𝐨𝐱𝐢𝐝𝐞 𝐢𝐧 𝐏𝐨𝐥𝐲𝐩𝐫𝐨𝐩𝐲𝐥𝐞𝐧𝐞: 𝐖𝐡𝐲 𝐌𝐞𝐥𝐭 𝐅𝐥𝐨𝐰 𝐈𝐧𝐝𝐞𝐱 𝐀𝐥𝐨𝐧𝐞 𝐈𝐬 𝐍𝐨𝐭 𝐄𝐧𝐨𝐮𝐠𝐡 In polypropylene (PP) production, melt flow index (MFI) is often treated as a defining property. However, identical MFI values (for example, 25 g/10 min at 230 °C / 2.16 kg) do not imply identical molecular structures or processing behavior—particularly when comparing fiber-grade PP and spunbond PP. ⚛️ Role of Hydrogen during Polymerization Hydrogen functions as a chain transfer agent during PP polymerization: • Terminates growing polymer chains • Reduces average molecular weight • Increases MFI • Preserves the catalyst-defined molecular architecture Hydrogen control is effective within a limited window. At elevated levels, it offers restricted control over molecular weight distribution (MWD) and may challenge reactor operability. ➡️ Hydrogen governs chain growth during polymerization but...

Most of the time, the resin isn't the problem — the wall thickness is. Here's what's actually happening: 🧊 Uneven cooling — thick sections (bosses, ribs, thick walls) stay hot and keep shrinking long after the surrounding thin walls have solidified. That continued shrinkage pulls the surface inward — that's your sink mark. 📏 The rule of thumb: ribs and bosses should stay at 50–60% of the nominal wall thickness. Go thicker "for strength," and you're almost guaranteed a visible sink on the opposite face. 🌡️ It's not just geometry — packing pressure, hold time, and gate location all affect how much material is fed in...

Sweden has announced plans to ban PFAS in certain consumer products, as part of their new national action plan on PFAS, which the government adopted on 23rd July. The Swedish government has opened a consultation on the proposed ban, which would restrict the use of PFAS in a range of products, including clothing, footwear, kitchenware, cosmetic products and ski wax. Read more in their press release (in Swedish). PFAS are a group of around 10,000 chemicals often referred to as ‘forever chemicals’ as they are highly persistent and take generations to break down in the environment. They are used in industrial manufacturing and in a wide range of consumer products due to their ability to repel both grease and water. Exposure to some #PFAS has been linked with adverse health impacts, including certain cancers, reduced fertility, and the disruption of the immune system. The Swedish government wants to act ahead of the EU universal PFAS ban that proposes to cover all 10,000 PFAS as a group. S...

A baby’s first steps are an important, memorable milestone. Baby walkers complement parents’ guiding hands, aiding an infant’s early mobility and exploration of their surroundings. Today, baby walkers come in compact, foldable designs and are embellished with various elements for infant entertainment and visual and tactile learning. As trends evolve, safety remains the foremost standard in baby gear design. Thermoplastic elastomers (TPEs) are ideal for these applications due to their soft-touch properties, impact absorption, slip resistance, and durability, helping improve safety and comfort in use. #KRAIBURGTPE , a global manufacturer of #thermoplasticelastomers and customized material solutions, offers specialized TPE solutions for baby gear applications, designed to deliver the required performance, durability, and functionality. Soft-touch advantage for comfortable use: KRAIBURG TPE materials provide a soft-touch surface that enhances comfort and improves the look and feel of baby...
