Fire Safety Science and Material Flammability

Cone calorimeter test underway at UDRI

Flame Retardant Material Design, Testing, Analysis and Connection to Real World Fire Safety Regulations

UDRI offers over 28 years of experience in flame retardant research and fire safety for all materials (wood, plastic, composites, aircraft materials metals, etc.) in all fire risk scenarios. We can deliver practical solutions to industrial, government and academic customers. We specialize in flame retardant and fire protection solutions that meet regulatory tests for just about all applications and materials in use today, including wildland fire and electric vehicle (lithium ion battery) fire protection. Research also covers combustion and emissions research of burning plastics for energy recovery and development of more sustainable fire safety solutions.

Research projects with UDRI in this area can simply involve fire testing, or can include product development and design. We also offer literature searches and analysis for patent and proposal writing that take advantage of an extensive intelligent database of fire safety, fire science and flame retardancy papers. We can also provide consulting services for meeting regulatory tests, troubleshooting and product development. With all projects, the customer owns all of the data and intellectual property unless UDRI is bringing existing technology to the project that requires licensing.

Our current research in fire safety science serves industry, academia and government customers, both in the United States and overseas. The Fire Safety Science Laboratory (FSSL) holds all of our test equipment, and the Quality Management System of the Fire Safety Science Laboratory is certified to ISO 9001:2015 (Eagle Certification Group, Cert No. 5587).
