Flammability chemistry
WebThe ability of the plastic part to extinguish or spread the flame after ignition. Its dripping behavior in response to a small open flame or radiant heat source under controlled laboratory conditions. This test is a preliminary sign to check the flammability of plastics used in any application. WebJan 9, 2024 · A combustion reaction is a major class of chemical reactions, commonly referred to as "burning." In the most general sense, combustion involves a reaction between any combustible material and an oxidizer to form an oxidized product. It usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water.
