UL94V0 Certified Sheets, Seals & Gaskets

In industries where flame resistance and safety compliance are critical, the use of UL94V0 certified silicone plays a vital role in protecting lives, ensuring regulatory compliance, and minimizing fire risks. Only UL-Certified materials can provide a Yellow Card.

However, a growing number of vendors are falsely claiming UL-certification. If you dig deeper, their products really may only claim to “meet UL94V0 standards” or are “tested to UL94V0”—without actually being UL-certified.

The Difference Between UL-Certified and “Tested to UL94V0”

• UL-Certified: A material that has undergone independent testing by Underwriters Laboratories (UL) and is officially listed in the UL database.
• “Tested to UL94V0” (Non-Certified Claims): A manufacturer’s internal or third-party test without UL oversight or verification. 

Be wary of vague wording like “engineered to meet UL94V0” or “UL94 compliant” instead of UL-certified. Only UL-certified material can offer a Yellow Card for compliance.

Here’s why this is a major risk for procurement teams, quality managers, and design engineers:

• Regulatory & Compliance Failures – Using non-certified materials can result in audit failures and non-compliance with industry fire safety standards.
• Safety Hazards – Without independent UL verification, fire resistance properties are unreliable and could lead to catastrophic failures.

• Liability & Legal Exposure – If a fire occurs and the material doesn’t perform, your company could face legal action and product recalls.
