ABS fire rating.

The fire protection grade of ABS is mainly divided according to UL94 standard, and it is divided into six main grades: HB, V-2, V-1, V-0, 5VB and 5VA from low to high. Among them, V-0 is a high flame retardant grade commonly used in electronic and electrical industries, and 5VA is the grade. ‌‌ all sciences How to rank from low to high?

The flame retardancy is enhanced in turn, and the specific order is as follows: Hb grade: the grade, horizontal combustion, slow speed, suitable for ordinary parts with low flame retardant requirements. V-2, V-1 and V-0: According to the vertical combustion test, V-0 has the flame retardancy and V-2 is the weakest.

Grade ‌5VB and 5VA: the grade, and 5VA has the strongest performance for more severe industrial environment.
