Huntsman Advanced Materials states it will highlight some of the significant applications its products are helping to enable at JEC Europe 2014.
According to Huntsman, projects including structural composites parts on the BMW i, composite bonders on a prototype racing vehicle’s rear spoiler and prepreg components on a Richard Mille luxury watch, illustrate the spectrum of applications that it will exhibit during the show.
Huntsman explains that in high-volume automotive manufacturing, epoxy composites are used for structural applications on luxury brands and are now ready for the mass production of vehicle parts.
Huntsman claim it continues to meet demands for faster processing and reduced composites production cycles with the development of epoxy resin systems for High Pressure Resin Transfer Moulding (HP-RTM) and compression moulding. Where HP-RTM is preferable for the efficient production of highly complex parts, compression moulding facilitates much faster production but is restricted to low complexity parts.
Huntsman says it is the first supplier to have produced epoxy resin systems that are qualified for the mass production of structural parts. Including preform set, injection, curing and de-moulding, the latest system, Araldite LY 3585 / Aradur 3475, allows parts production in five and three minutes respectively in HP-RTM and compression moulding, exhibiting a one minute latency at 110°C. For HP-RTM, the company claims this equates to a 30% time saving when compared with first generation HP-RTM. Aided by computer simulation capabilities which speed-up ideal processing parameters identification, within its state-of-the-art laboratories in Basel the company develops fast and flexible epoxy systems designed with superior properties to meet the automotive sector’s demands for continuous improvements.
During the show, Huntsman says the resin systems for HP-RTM that produce high levels of targeted performance on vehicle wheel rims will also be showcased.
Huntsman’s Technical Support Applications & Processes Team Leader, Stephan Costantino, will give a presentation at the show on “Fast and cost efficient solutions for automotive mass production”, during which Araldite resin systems for compression moulding and HP-RTM will be highlighted as new developments enabling very short cure cycle times.
