Abstract : This study experimentally investigates the mechanical stability and deformation mechanisms of flame-retardant polyvinyl chloride (PVC) compositions developed for fire-resistant cable sheaths. The mechanical properties of Germetik35 and Germetik-45 compositions under tensile and compressive loading were evaluated using a universal testing machine according to a methodology closely aligned with ISO 527 and ASTM D638 standards. Force-elongation and stress-strain relationships, together with maximum load, maximum stress, relative deformation, and elastic modulus, were determined to characterize the structural behavior of the compositions. The results demonstrated that the Germetik-45 composition exhibits higher mechanical strength and greater resistance to deformation, whereas Germetik-35 possesses relatively higher elasticity. The effective interaction between flame retardants and the PVC matrix promotes a more uniform stress distribution, thereby improving the mechanical integrity and operational reliability of cable sheaths under fire conditions.
