Silicone and epoxy hybrid resins exhibit wide range of mechanical properties

The largest range of silicone and epoxy hybrid resins for the 3D printing of wearable devices, biomedical equipment and soft robotics has been developed by researchers from the Singapore University of Technology and Design (SUTD). In a study published in Applied Materials Today, the range of tunable functionally graded materials, which displayed over five orders of magnitude of elastic modulus, demonstrated excellent interfacial toughness, higher precision in complex structures and better fabrication control for the integration of mechatronic components.

Progress in bio-based itaconate butadiene rubber

Bio-based itaconate butadiene rubber has been introduced by the Beijing University of Chemical Technology. This project was researched by professor Liqun Zhang’s team at the university. They started the research in 2008. After 13 years of hard work, a new generation of high performance and bio-based itaconate butadiene rubber has been successfully developed. Epoxy group functionalized poly(dibutyl itaconate-co-butadiene- glycidyl methacrylate) (PDBIBG) is the first class of macromolecular chain structures based on an itaconic acid resource which can realize the high value-added utilization of biomass resources and promote green and sustainable development within the rubber industry.

HeatBoss EPDM: High heat resistant EPDM promising for SAE J200 applications

In modern cars, the space for the engine compartment is continuously shrinking for both functional and aesthetic reasons. Increasing vehicle compactness by reducing the space available for design engineers results in hotter engine components which restrict the rubber materials that can be used. This has boosted a fast growing demand in the rubber industry for elastomer parts with durability and increased resistance to temperature extremes. Among elastomers, silicone elastomers and fluoroelastomers show very effective heat resistance resulting from the strong Si-O and C-F bonds present in their chemical structure. However, the main drawbacks are their high price and high processing cost that make compounding, molding and final production very expensive

Part design simulations for silicone rubber components

The successful design of medical device components is increasingly dependent on simulations based on finite element analysis (FEA). Simulations provide a rapid and cost-effective way to determine optimal construction of multi-component systems, as well as information on how components interact with each other during use. Investing in accurate, early design simulations can provide significant resource savings by decreasing the amount of iterative loops necessary in the prototype process to validate the overall device design for FDA or other governing body approvals.

Seals prevent bearing damage in EVs

Freudenberg Sealing Technologies’ new generation electrically conductive seals prevent bearing damage caused by electrically induced corrosion, and also increase electromagnetic compatibility. Electric cars with drive systems that operate at 800 volts instead of the usual 400 can recharge in just 15 minutes, and produce enough power to drive several hundred kilometers. The power semiconductors in the inverter ensure that the direct current stored in the battery is converted into the alternating current required by the electric motor while driving. These power electronics are often positioned directly above the electric motor, and are also known as electric engine injection systems.

An overview of the silicone recycling process

With global annual production of silicone expected to grow to 2.9 million tons by 2025, it is increasingly important to have an environmentally-friendly end-of-life option for silicone products. The current solution for discarding silicone scrap is to either landfill or incinerate it. Both of these are detrimental choices for the environment.
