UL 94 Flame Rating Comparison

Standard Acrylic vs YG FlameGuard™ Flame Retardant Acrylic Sheet

Standard acrylic sheets typically achieve only the UL 94 HB horizontal burning grade,
while YG FlameGuard™ Flame Retardant Acrylic Sheet has passed the more demanding
UL 94 V-0 vertical burning test, demonstrating superior
fire safety and flame-retardant performance compared with general plastics.

UL 94 Flame Rating Comparison Table
Rating	Test Direction	Requirements	Difficulty	Common Materials
HB	Horizontal Burning	Burning rate ≤ 75 mm/min or does not reach mark line	⭐ (Easy)	Standard Acrylic, ABS, PC
V-2	Vertical Burning	Dripping allowed; must self-extinguish within 30 s	⭐⭐	Modified Plastics, FR ABS
V-1	Vertical Burning	No dripping; must self-extinguish within 30 s	⭐⭐⭐	FR PC, FR Nylon
V-0	Vertical Burning	No dripping; must self-extinguish within 10 s	⭐⭐⭐⭐ (Most Stringent)	YG FlameGuard™ Flame Retardant Acrylic, FR PC

V-0 rating is among the highest classifications in the UL 94 standard,
indicating that a material can self-extinguish within 10 seconds after the flame is removed
with no dripping or secondary ignition. For more details, visit the
