Johns Manville (JM), a market-leading manufacturer of continuous filament glass fiber and a Berkshire Hathaway company, announced today the introduction of a new chopped strand: ThermoFlow® 641 for reinforcement of polypropylenes.
ThermoFlow® 641 Chopped Strands are designed to provide superior as-molded mechanical performance in polypropylene as well as high detergent resistance. The product will be introduced this week at the JEC World 2017 Composites Show in Paris. The JM booth is at Hall 6-G32.
“JM continues to bring new products to market in engineered and structural thermoplastic composites to serve our customers,” said Jared Cox, Global Chopped Strands Product Manager for Engineered Products - Fibers. “ThermoFlow® 641 capitalizes on JM’s professional expertise in technical service, product technology and builds on its leadership position in polypropylene reinforcement in Europe and North America.”
ThermoFlow® 641 delivers exceptional composite mechanical properties in polypropylene and is designed to perform in detergent resistant applications, such as washing tubs in appliances. The improved color performance and low yellowness enables compounders to further increase the use of polypropylene in general purpose consumer applications. The improved flow also yields more consistent properties in the final part.
