Johns Manville introduces new glass fiber for auto parts

Introduction of a new chopped strand glass fiber for high-performance polyamide

Johns Manville (JM), a manufacturer of glass fiber products and a Berkshire Hathaway company, recently announced the introduction of a new chopped strand glass fiber for high-performance polyamide (PA66) designed for automotive applications requiring combined hydrolysis performance and reduced weight. “Lightweight and long-term performance are important drivers for automotive engineers who are designing cost-effective solutions for next-generation automotive components with engineered thermoplastic polymers,” said Brian Sapp, Global Fibers business director for JM Engineered Products.
The new ThermoFlow® 675 provides improved mechanical properties in tensile strength and improved impact performance vs. standard short-glass fiber chopped strands. ThermoFlow 675 reportedly maintains the high flow feeding performance of current ThermoFlow chopped strands with low fuzz and less downtime to the benefit of customers using large extruders – even with high glass load.
“Our commitment to continuously innovate and replace metal with short- and long-glass fibers engineered thermoplastics will support our global customers who are seeking new solutions and materials to support their growth,” said Sapp.
