Ashland Composite Polymers, a division of Ashland Inc. demonstrated a number of new resins at booth 718, and support the first electric car towards a new land speed record.
The new line of polyester and vinyl ester resins formulated specifically for the vacuum infusion process, produce a more structurally sound composite part in a “worker-friendly” environment with less resin waste. The new robust group of resins for infusion moulding include its Hetron, Modar, Aropoltm and Ame 2000 lines which aim to bring low viscosity and superior infusion performance to industries ranging from marine to mass transit.
“We’re pleased to offer a new infusion line of resins that meets the environmental concerns and production needs of today’s demanding marketplace,” said Dwight Rust, business development manager, Ashland Composite Polymers. “The high performance properties of our resins combined with the vacuum infusion process will provide dependable reactivity, excellent flow and rapid infusion.”
Ashland have also developed Arotran HMR for composites that they claim will virtually eliminate paint popping in OEM paint ovens. The resin was demonstrated at their booth during the show to illustrate the benefits of using Arotran HMR resin.
“Parts moulded with sheet moulding compound containing Arotran HMR resin resist paint popping in OEM paint ovens. The parts also are more resistant to cracking and crazing,” said Scott Hoertz, global marketing director, Ashland Composite Polymers. “These desirable features make this resin perfect for automobile and truck composite applications.”
Ashland have also issued a new corrosion-resistant Aropol Q7022 T-08 polyester resin, designed for underground storage tanks. Aropol is a low-styrene polyester resin that lowers hazardous air pollutant (HAP) emissions and is claimed to have less than 35 percent styrene while providing corrosion-resistance to petroleum products, alcohols and alcohol-gasoline mixtures.
“This resin is suitable for any open molding application and can be customized to meet fabrication needs,” said Carl Gleditsch, technical service chemist, Ashland Global Technology. “Q7022 offers an economical alternative to other low-HAP resins targeted for UL1316 and UL1746 regulated applications. The product provides excellent wet-out of glass fibres, tailored room temperature cure properties and demonstrated corrosion resistance as measured in the relevant UL test protocols.”
Gleditsch presented a technical paper “Novel New Low-Styrene Resin for Underground Storage Tanks” on Wednesday afternoon and there was also a demonstration by Ashland on ""The Basics of Infusion Moulding"" on Thursday in the demonstration area.
An electric vehicle student-engineered at The Ohio State University (OSU) and supported by Ashland Specialty Chemical, recently became the first electric car to break the 300-mph barrier. Dubbed theBuckeye Bullet, the car set an historic mark at 308.317 mph during testing at the Bonneville Salt Flats, Utah in August. Students are due to return there on Oct 13-16 in an effort to officially set the world electric land speed record.
The Buckeye Bullet features a carbon-fibre polymer composite body infused with one of Ashland’s premium epoxy vinyl ester resins. The vehicle’s tooling utilizes an Aropol polyester resin for overall strength and durability.
Fibrelite reports that since the start of its partnership with Trenwa more than 100 precast trench systems integrating Fibrelite composite covers have been sold for use in electrical substations, wastewater treatment plants, chemical refineries and many other applications across North America.
