FAQs
Do you have UL94 V-0 certification? Can you provide a UL File Number verifiable on ul.com?
UL94 HB (Horizontal Burn): Confirmed and tested, sample reports available
UL94 V-2 (Vertical Burn, drips allowed): Confirmed and tested, sample reports available
UL94 V-0 (Vertical Burn, 10 seconds self-extinguish, no drips): Application submitted to UL Guangzhou Q3 2026, testing scheduled at CTI Shenzhen, expected certificate delivery Q4 2026
UL94 5VA: Not planned currently (specialized aerospace/military grade)
For projects requiring UL94 V-0 immediately, we recommend splitting your PO: standa
What flame retardant additive do you use? Is it halogenated, halogen-free, or antimony-free?
Halogen-free and antimony-free formula using a synergistic system of:
Metal hydroxide (aluminum trihydroxide, ATH): primary flame retardant, releases water on heating
Phosphorus-nitrogen synergist: secondary flame retardant, forms char layer to block oxygen
No brominated or chlorinated compounds (avoiding REACH SVHC restrictions on decaBDE, HBCDD)
No antimony trioxide (Sb2O3) (Prop 65 listed as possible carcinogen)
Why this matters for B2B buyers:
Can you customize density and hardness? How does density affect flame retardancy?
Parameter Standard Range Custom Range
Density 60 to 300 kg/m3 40 to 400 kg/m3
Hardness Shore C 30 to 70 Shore A/C full range
Thickness 0.5 to 50 mm Custom up to 100 mm
Color Black, white, gray standard Custom Pantone (MOQ 500 m2)
Density and flame retardancy relationship (technical honesty):
Lower density (60 to 100 kg/m3): more air voids, faster oxygen access, harder to achieve V-0 without high additive loading
Medium density (100 to 200 kg/m3): sweet spot for balance of flame retardancy and m
Does the flame retardant performance degrade after long-term high-temperature aging?
For applications below 100 degrees Celsius (furniture, packaging, consumer electronics), our formula maintains rated flame retardancy for 5+ years
For applications above 100 degrees Celsius (EV battery under thermal event, industrial equipment), we recommend our upcoming UL94 V-0 formula with heat-stable phosphorus-nitrogen system (Q4 2026)
For continuous operation above 120 degrees Celsius, EVA is not the ideal material choice. We recommend switching to silicone foam or PU foam for those applic
