Consider specialty compounds to take advantage of growing interest in molded liquid silicone rubber. Advantages of silicone rubbers include flexibility, thermal stability over a broad temperature range, resistance to solvents, and excellent biocompatibility. Silicones are increasingly being selected by design engineers for valve seats or hoses in autos and aircraft, where their resistance to solvents can be boosted through incorporation of fluorosilicones. Polyurethane is added to improve tear strength for some medical applications. New developments in specialty compounding were reviewed by Mary Krenceski, a research scientist at Extreme Molding in Watervliet, NY at Molding 2008.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
