Hexion reports its net sales for the year ended 31 December 2015 were US$4.1 billion, a decrease of 19% compared with US$5.1 billion in 2014. Net sales for Q4 ended 31 December 2015 were US$909 million, a decrease of 22% compared with US$1.16 billion in the prior year period. The decline in net sales was primarily driven by the strengthening of the US.dollar against most other currencies and lower selling prices from the decline in oil-driven feedstocks, which more than offset gains in specialty epoxy resins, the company said. Total segment EBITDA decreased 20% to US$73 million, compared to 2014, reflecting the strong US dollar and the absence of US$13 million in favorable one-time items in the fourth quarter of 2014. ‘Excluding the impact of currency, we were pleased to deliver an 11% year-over-year increase in Segment EBITDA in 2015 compared to 2014 due to the strength of our diversified portfolio and disciplined cost controls,’ said Craig O Morrison, chairman, president and CEO. ‘In 2015, we also drove strong levels of cash flow from operations and successfully completed construction of two new formaldehyde sites, with a third new formaldehyde site coming online as expected in the first quarter of 2016.’ ‘Our fourth quarter 2015 results reflected improvement in our specialty epoxy and versatic acids and derivatives businesses as well as productivity gains, offset by the negative impact of foreign currency, softer demand in Latin America and continued headwinds impacting our oil and gas related products,’ he added. ‘The structural cost savings program we began implementing earlier this year remains on track and we have identified approximately US$35 million in additional productivity savings to strengthen our position for profitable growth in response to the recent economic volatility.’ This story uses material from Hexion, with editorial changes made by Materials Today.

« Toyota developing wearable mobility device for the blind and visually impaired | Main | Juniper forecasts HEV & EV sales to total 17M by 2020; Tesla ranked leading EV manufacturer » Continental Structural Plastics (CSP) has signed a memorandum of understanding with Mitsubishi Rayon (MRC), regarding the development and manufacturing of innovative carbon fiber structural components for the automotive industry in North America. Under the MoU, CSP and MRC will begin detailed studies to substantiate the establishment of an equity-based joint venture. Specifically, the new joint venture will produce compression molded components made from carbon fiber reinforced plastic materials, which could include carbon fiber sheet molded compound (SMC) and/or Pre-preg carbon fiber Compression Molding (PCM).These components will include Class A body panels, as well as non-class A structural automotive applications including: pillars; engine cradles or supports; radiator supports; frames and rails; bumper beams; underbody shields; door inners and intrusion beams. JEC Innovation Award. Continental Structural Plastics recently received the JEC World 2016 Innovation Award in the Automotive Exterior Parts category for its multi-material decklid concept. This decklid, featuring a TCA Ultra Lite outer and a carbon fiber resin transfer molded (RTM) inner, weighs 12.11 lbs. (5.5 kg.)—a 13% weight savings over a similar decklid made from aluminum. The decklid was developed as part of a study to compare the weight of decklids made from steel or aluminum versus a multi-material approach. Also key was reducing the cycle time associated with the use of carbon fiber. The carbon fiber RTM structural inner component represents a number of breakthroughs in the use of recycled carbon fiber materials for cost-effective mass production applications. Using preformed carbon fiber mats infused with a Hexion fast-cure, epoxy-based resin played a key role in CSP being able to successfully reduce the cycle time associated with high carbon fiber content RTM. From injection time to cure to completion, the total cycle time for this component is 2.5 to 3 minutes. In addition, the infusion tool used to create functional prototypes was developed and produced using 3D printing. The entire process can be completed in 2-3 weeks. This is significant because it will enable CSP to take design data and provide an OEM with a functional prototype part in a significantly reduced timeframe than what is currently customary. Finally, to further reduce costs and control quality, CSP is developing a process to manufacture its own carbon fiber mat using various carbon fiber content. Introduced by CSP in 2014, and currently in production on the 2016 Chevrolet C7 Corvette, TCA Ultra Lite is a 1.2 specific gravity material that offers as much as a 40% weight savings over standard density composite materials. It provides automakers an opportunity to achieve a Class A finish with a material that is E-coat oven capable, and resistant to corrosion, dents and dings. Because there is no degradation of mechanical properties, lighter parts molded with TCA Ultra Lite do not have to be made thicker, or incorporate structural reinforcements, to maintain the desired performance qualities. Specifically, Ultra Lite technology uses treated glass bubbles to replace Calcium Carbonate (CaCO ), allowing the resin to adhere to the matrix and increase the interfacial strength between the bubble and the resin. This is a patented treatment technology that results in a more robust resin mix that makes molded parts more resistant to handling damage, and prevents the micro-cracks that cause paint pops, pits and blistering. The product also uses Owens Corning Advantex glass technology which can be manufactured with lower environmental impact compared to other glass types. Glass reinforced polymers can have a lower global warming potential (GWP) than steel in the production and use phase for automotive applications such as body parts. In addition, TCA Ultra Lite provides the benefits that come with using a composite over a metal, including significantly reduced tooling costs (50 percent or more, depending on production volumes) and the ability to achieve unique design cues such as deep draws that can’t be achieved with a stamped metal. In late 2015, CSP received the CAMX Unsurpassed Innovation Award and the SPE Grand Award for this material technology.

Hexion Inc has recently expanded its waterborne epoxy resin production capacity in Tianjin, China. The project, which will take advantage of modern technologies including a new reactor, will allow Hexion to meet increasing demand for its waterborne epoxy products used to made sizing for glass or carbon fibers used in wind energy, automotive and aerospace applications. Hexion will now be able to locally produce and shorten supply times for a broad range of epoxy resins, curing agent and modifiers. ‘Waterborne technology offers manufacturers a more sustainable alternative to solvent-based coatings by reducing volatile organic compounds,’ says Terry Shao, Hexion's regional market development manager for China.

The purpose of ANSI 118-15 and 118-11 is to facilitate design of high performance ceramic tile adhesives with improved bond strength on cementitious and plywood substrates. For these polymer modified mortars, the quantities of constituent materials must be properly selected to significantly increase bond properties of the tile adhesive. Consequently, interactions between all the components, such as the adhesion mechanisms between the latex film and the substrate and the effect of water on bond performances at the micro-level must be understood in order to design high performance polymer modified tile adhesives. The influence of percentages by mass of cement, latex polymer and cellulose ether were investigated. Results showed that the relative concentrations of these constituents exerted an influence on the adhesive properties of the mortars. To obtain maximum end use values, optimum dosages are to be found using design tools such as the ceramic tile adhesives design methodology presented herein. © 2015 Elsevier Ltd. All rights reserved.
