High fire resistance property Enhanced polyamide with high CT1 value

This invention discloses reinforced polyamide with high CTI value and high flame retardancy. The reinforced polyamide comprises: polyamide 3-60 wt.%, polymerizing flame retardant 5-25 wt.%, flame retardant aid 1-20 wt.%, lubricant 0.5-5.0 wt.%, surface modifier 0.1-2.0 wt.% and reinforcing component 10-50 wt.%. The obtained reinforcing polyamide has high CTI value and good flame retardancy at the same time, thus having excellent flame retardancy and excellent electric properties.
