CRP-1 The FM 4910 specification was created in response to requirements regarding the quantity of toxic smoke that can be emitted from some materials when exposed to high heat or flame. FM stands for Factory Mutual, the company that originally experienced a tragedy due to burned materials releasing toxic smoke. This led to the creation of the specification, and the materials that meet the stringent requirements are used in applications such as aircraft, semi-conductor, and highly chemical environments.
CRP-1 These materials are created to limit fire propagation, the spread of flame on the material, and smoke generation or the quantity of smoke generated by igniting the material. FM 4910 meets UL 94 V-0 flame test criteria and can withstand temperatures from 140 to 425°F. These materials also perform well in wet process applications and resist acids, bases, solvents, and oxidizers. Common applications include; tanks, vessels, and machine parts, and clean rooms, cabinets, enclosures, and view windows.
