The virtual simulation technology

which is applied to the experimental teaching of polymer materials and engineering with strong practicality

is an important means for students to improve their ability of finding

solving and operating problems and cultivating high-quality innovative talents. The construction of virtual simulation experiment teaching project of thermal oxidation degradation and combustion process test of flame retardant modified polymer and its application in professional experimental teaching is discussed in this paper. Its teaching effect fully reflects the effectiveness of online experimental teaching and the compatibility with traditional experimental teaching mode. Meanwhile

the improvement direction of virtual simulation project construction has also been clarified

and the construction of all kinds of first-class experimental teaching courses is also promoted further. Therefore

virtual simulation experiment plays a positive role in enriching experimental teaching resources

cultivating students' experimental skills and promoting the quality of talent training.
