Is UL 94 V-0 the Same as UL94V0?
Yes, UL 94 V-0 is the same as UL94V0. The proper way to cite this specification is UL 94 V-0, but some part drawings may callout UL94V0 instead.
What Is a UL 94 V-0 Silicone?
UL 94 V-0 silicone refers to a silicone rubber material that meets the stringent UL94 V-0 flammability standard set by Underwriters Laboratories (UL). This standard classifies materials based on their ability to extinguish after being exposed to a vertical flame. To earn a V-0 rating, a silicone specimen must stop burning within 10 seconds after two flame applications, without dripping flaming particles that could ignite surrounding materials. This makes UL94 V-0 silicone ideal for applications where fire safety is a critical concern.
Silicone rubbers inherently offer good thermal stability and low flammability, but specialized formulations are needed to meet UL94 V-0 requirements. Flame retardant additives, such as silica, aluminum hydroxide, or proprietary halogen-free compounds, are typically incorporated to improve the silicone’s fire-resistant properties without compromising its flexibility, temperature range, or chemical resistance.
UL 94 V-0 silicone is widely used in electronics, aerospace, automotive, and industrial applications where regulatory compliance and fire safety are mandatory. Common uses include electrical insulation, gasket materials, thermal interface pads, and enclosures for sensitive components. These parts must perform reliably in high-temperature environments while reducing fire risks and meeting safety standards.
In addition to flame resistance, UL 94 V-0 silicone maintains typical silicone benefits such as weatherability, ozone resistance, and consistent performance over a wide temperature range—from -60°C to +230°C. Some formulations also meet additional standards such as RoHS, REACH, and FDA compliance.
Choosing a UL94 V-0 silicone is essential when a project requires both flame retardancy and high-performance elastomer properties. It ensures that the final product meets safety regulations without sacrificing durability, making it a trusted material in high-stakes environments like consumer electronics, EV battery housings, LED lighting, and aerospace systems.
