Vydyne R550HR BK0777 is a 50% glass-filled, heat-stabilized PA66 based resin designed for injection molding applications. It was specifically developed to withstand long term exposure to coolants at temperatures up to 135°C. R550HR BK0777 maintains the excellent resistance typical of PA66 in chemicals, machine and motor oils, solvents, and gasoline.
