Johns Manville adds that ThermoFlow® 636 has been designed for automotive applications, such as inlet manifolds and front-end carriers to reduce weight of structural parts.

"Lightweight and long heat exposure performance are important drivers for automotive engineers designing cost effective and increasingly demanding automotive components with engineered thermoplastic polymers," said Enno Henze, senior vice president of Johns Manville’s Engineered Products Europe/Asia business.

Johns Manville say that ThermoFlow® 636 improves mechanical properties such as tensile strength and impact resistance by 10% compared with standard short glass fibre chopped strands. ThermoFlow® 636 is available in 10 and 13 micron fibre diameters, and is claimed to maintain the good high flow feeding performance of current ThermoFlow® chopped strands with low fuzz and less downtime to the benefit of our customers using large extruders even with high glass loadings.
