Abstract
This article discusses the effect of the cross-linking of diene elastomers (BR, SBR, NBR), with the use of an organic peroxide or sulfur, on their flammability and fire hazard. Flammability tests were carried out by the method of oxygen index, combustion time (in air) and ignition temperature measurements. Fire hazard was determined on the basis of test results obtained by means of a cone calorimeter. Toxicometric coefficients (\( {\text{RTFH}}_{{{\text{co}}/{\text{co}}_{ 2} }} \) and WLC50SM) and the emission of polycyclic aromatic hydrocarbons (PAH) were determined. Test results were interpreted from the point of view of the chemical constitution of elastomer macromolecules as well as the structure of its network structure.
