High Temperature Rubber Hoses

Working temperature ranges from -45℃ to 260℃ , the maximum can arrive at +300℃ in a short time ; The bursting pressure is over 3 Mpa under +200℃ and over 10 Mpa under normal temperature . After getting aging under +200℃ for 168 hours , the hoses will still keep the bursting pressure over 3 Mpa and not fracture on their surface , the pulse frequency keeps over 200 thousand . Furthermore , we make up a standard for the products with Changchun Automobile Material Research Centre .
