Effect of Aluminium Hydroxide on Thermal, Dynamic Mechanical and Dielectric Properties of Hexafluoropropylene-vinylidinefluoride Elastomeric Composites

Abstract

Abstract. Aluminium hydroxide (ATH) particles were incorporated at different loadings into fluorocarbon rubber (FKM), to study the effect of filler loading on the cure characteristics, mechanical properties, dynamic mechanical properties and thermal stability. The mechanical properties of FKM/ATH composites were better than medium thermal black filled vulcanizates. The storage modulus (E') of the composites was found to increase due to the enhancement in stiffness. The viscoelastic properties revealed that there is a strong interaction between the polymer and the filler. The dielectric permittivity, AC conductivity and absorption coefficient of the highly ATH loaded systems are much greater than the unfilled and lower systems.
