SWM International recently introduced Naltex flow media for resin-infusion processes to its host of offerings. This new flow media is engineered to retain up to 15% less wasted epoxy resin, which is commonly trapped in media grid apertures after processing — while maintaining high flow rates compared to current technology.
Designed for wind energy resin transfer molding (VARTM) processes, Naltex resin infusion media also features a soft, flexible edge that is safe for use with sensitive vacuum bags that are prone to abrasion and puncture. In addition to partnerships with external testing agencies, SWM has also designed and fabricated its own internal flat panel VARTM testing station to simulate real-world processing conditions.
“This innovative, new flow media technology was engineered with our customers’ needs in mind,” said Daniel Lister, Executive Vice President of SWM’s Advanced Materials and Structures division. “As flow media is a single use product that is disposed of after use, it was paramount to find a solution that reduced the amount of retained resin after a lay-up, while maintaining high flow performance.”
The Naltex family of diamond net flow media includes a variety of resin material options, engineered to withstand high temperatures, improve “drape-ability,” increase flexibility, and reduce the amount of retained resin within the media apertures. Configurations are also available for applications that require low, medium, and high flow rates.
In addition to extruded netting, SWM also manufactures thermoplastic polyurethane (TPU) film and provides custom lamination and slitting services. SWM manufacturing facilities are ISO 9001-certified and located in the USA, Europe, and Asia.
