Recently，our PP halogen-free intumescent flame retardant FR-PP NP can reach UL94 5VA in modified PP! It opens up a new field of flame retarded PP,and also is the highest level of flame retarded PP.
In UL94 test, 5VA is the highest grade of FR test. Bar and plaque specimens are tested at the same time, and the flame intensity is 500W which is different than 50W in the UL94 V grade test. The details of test information is listed below.
