How to Select Thermal Material Products Based on UL Flammability Rating

Thermally Conductive Material

Learn about the UL 94 rating system: UL 94 is a commonly used flammability rating system used to test the burning characteristics of plastic materials. According to the UL 94 rating, materials can be classified into V-0, V-1, V-2, and HB grades, with the V-0 grade indicating the highest flame retardant performance.

Determine Application Requirements: Understand the requirements for thermally conductive materials for your specific application. Consider temperature range, environmental conditions, and other safety and reliability requirements.

Find a material's UL 94 rating: Consult the technical specifications and safety data sheet of the thermally conductive material product under consideration to determine its UL 94 rating. This will usually specify the flame retardant performance level of the material.

Choose the Appropriate Rating: Choose a thermally conductive material with an appropriate UL 94 rating based on application needs and safety requirements. If a high degree of flame retardancy is required, give priority to materials rated V-0.

Consider other factors: In addition to the UL 94 rating, thermal conductivity, mechanical properties and other relevant technical indicators should also be considered. Make sure the selected material not only has the appropriate flammability rating but also meets other application requirements.

Reference Supplier Guidance: Consult with thermal conductive material suppliers or manufacturers to learn whether their products meet UL 94 rating requirements and to obtain relevant technical support and advice.

Please note that the UL 94 rating is an important reference indicator, but not the only evaluation criterion. When selecting a thermally conductive material product, you should also consider other factors, such as thermal conductivity, material reliability and durability, to ensure the product selected meets your specific application needs and standards.
