UL 94 V-0 Flame Retardant Silicone Sheet

ElastaPro manufactures high-performance, flame-retardant solid silicone sheeting engineered to meet stringent fire, smoke, and toxicity (FST) safety requirements. Our premium compounds are specifically formulated to satisfy the UL 94 V-0 standard, ensuring that the elastomer self-extinguishes within 10 seconds after a flame source is removed and prevents flaming drops from igniting materials below.

These specification-grade silicone sheets deliver exceptional thermal insulation, ozone resistance, and environmental sealing for critical defense, aerospace, mass transit, and electronic enclosure applications.

Industry and Regulatory Compliance

Our flame-retardant HCR (High-Consistency Rubber) formulations are traceable and compliant with leading industrial safety standards:

  • UL 94 V-0 Certified (Vertical Burn Tested)

  • FDA 21 CFR 177.2600 compliant ingredients available upon request

  • FAR 25.853 vertical burn standards for aerospace interiors

  • REACH and RoHS compliant

What is the UL 94 V-0 Rating?

The UL 94 standard measures how plastic or elastomer specimens react to a controlled flame. The V-0 classification is significantly more rigorous than V-1 or V-2 ratings, requiring strict self-extinguishing behavior under vertical orientation testing constraints.

UL 94 Vertical Flammability Test Mechanism

To achieve a V-0 rating, the silicone specimen must:

  1. Stop burning within 10 seconds after the test flame is removed.

  2. Not exceed a total flaming combustion time of 50 seconds across 5 samples.

  3. Not drip any flaming particles that could ignite the surgical cotton placed directly beneath the testing rig.

Frequently Asked Questions

Does ElastaPro supply official UL 94 V-0 yellow cards?

Yes. Our flame-retardant materials are formulated to perfectly align with Underwriters Laboratories standards. We provide full lot traceability, material test reports (MTRs), and certifications of compliance to fulfill your quality control and AS9100D auditing requirements.

What makes silicone inherently flame retardant compared to organic rubbers?

Silicone possesses a backbone of alternating silicon and oxygen atoms (Si-O-Si), which requires significantly higher energy to break down than the carbon-carbon chains found in organic elastomers. When exposed to extreme flame, ElastaPro’s V-0 compounds form a non-conductive, fire-resistant silica ash layer that protects underlying substrates and retards flame propagation.

Can these flame-retardant sheets be used for outdoor environmental seals?

Absolutely. In addition to flame resistance, our solid silicone sheeting features exceptional resistance to UV degradation, ozone cracking, moisture ingress, and extreme temperature cycling. This makes them ideal for outdoor telecommunication boxes, railcar HVAC seals, and marine electronics enclosures.
