Study of the Characteristics of the Elasticity of Silicone Rubber Composites RTV 10 and RTV 52 with Talc Reinforcing Powder

Abstract

Insole made of silicone rubber material is capable of dampening heel strike during walking and running activities due to its high elasticity. To meet specific requirements, the elastic properties of silicone rubber can be modified by using it as a composite material by adding talc powder as a reinforcing agent. This study examines the elasticity characteristics of silicone rubber RTV 10 and 52 mixed with talc ranging from 5% to 35%. The testing is conducted by compressing specimens to a certain depth, and then measuring the compressive force and dimensional changes of the specimens. The test results indicate that the higher the percentage of added talc, the lower the change in diameter and the higher the compressive force.
