Profile: Keller Products Inc. specializes in providing plastic extrusions. Flame retardant package is added to the thermoplastic material, which must be effective, utilized at a minimum loading, and be safe. They cannot affect any of the properties of the material or adversely affect processing it. We generally use non-halogenated flame retardants in synergy with smoke suppressant technology so they provide an increase in the materials resistance to ignition, reduce the burn rate, reduce the spread of smoke emissions and flames, while minimizing the plastic dripping during combustion. We even offer a plastic that is flame retardant and biodegradable.
