AOWEIDA
Fire-Retardant Black EVA Foam Sheet (UL94 HF-1)
AOWEIDA manufactures fire-retardant black EVA foam sheets that pass the UL94 HF-1 horizontal burn rating — the strictest HF classification for foam materials. Our flame-retardant EVA is engineered for applications where safety, smoke suppression and self-extinguishing behaviour are non-negotiable: appliance insulation, automotive gaskets, packaging for electronics, acoustic panels and industrial sealing.
What Does UL94 HF-1 Mean?
UL94 is the globally recognised flammability standard from Underwriters Laboratories. The HF-1 rating means the material stops burning within a short window after the flame is removed and produces no flaming drips. HF-1 is a stricter grade than HF-2, making it the right choice when your product must meet export safety requirements or end-client flammability specifications.
Maximum Sheet Size: 1m x 2m x 50mm
Our fire-retardant EVA sheets are available up to 1m x 2m (1000mm x 2000mm) with a maximum thickness of 50mm. Need a smaller size or a custom thickness? We cut to your exact requirements — length, width and thickness are all customisable to match your production line.

Frequently Asked Questions
Can you cut the fire-retardant sheet to my custom size?
Yes. While our maximum sheet is 1m x 2m x 50mm, we cut to any smaller length, width or thickness you specify. Send us your drawing or dimensions and we will quote accordingly.
What is the difference between UL94 HF-1 and HF-2?
HF-1 is the stricter rating. Both measure horizontal burning, but HF-1 requires the material to self-extinguish more quickly and allows no flaming drips, while HF-2 permits flaming particles. HF-1 is preferred for most safety-critical applications.
Can you provide a UL94 test certificate?
Yes. We can supply the UL94 test report or a third-party test certificate with your order, and our factory also holds ISO 9001, REACH and RoHS certifications.
Do you offer other colours or densities?
Yes. Black is our standard for fire-retardant EVA, but we can match other colours and adjust density (typically 60–200 kg/m³) and hardness to your application.
What is the minimum order quantity?
MOQ depends on thickness and size. Contact our sales team with your specification for a fast quotation and sample arrangement.
