Styrene-Butadiene (SBR) Rubber: Uses, Structure & …

Key Features: Good resilience and tensile strength Outstanding resistance to abrasion and fatigue Low resistance to oil, other hydrocarbon fluids and ozone Styrene Butadiene Rubber Vs Natural Rubber While most of the properties of SBR are comparable with NR, but in some respects like heat build-up, tack and gum tensile strength make it inferior to natural rubber.

Stability and stabilization of polymers under irradiation

appliion, it exhibits dramatically enhanced resistance to radiation-induced changes in properties from degradation (scission) effects. For pre-crosslinked PTFE, the radiation resistance is increased by 2 orders of magnitude. For a copolymer of C2F4 and C2F6

Effect of zinc oxide type on ageing properties of Styrene …

2010/3/1· The presence of zinc oxide in rubber compounds is tried to be minimized due to environmental concerns. In this study; the effect of different zinc oxide types on ageing properties of SBR compounds was investigated. Active zinc oxide and zinc oxide coat on CaCO 3 core were used in SBR compounds and their ageing characteristics were compared.
