Following a ban on many materials containing bisphenol-A, new bisphenol-free Boron silicates have been found as substitutes.
The purpose of this study is to describe the mechanical properties of these bisphenol-free magnetoactive borosilicate polymers
containing hard magnetic particles. Samples of 0%, 33% and 66% by wt. were loaded for compression using a universal
testing machine. The maximum forces occurring for different travel speeds were compared before and after post-magnetization
treatments. The post-magnetization included 2 stages. In addition, the change in mechanical properties within 24 hours after
the post-magnetization process was investigated. Furthermore, the influence of speed and particle content were investigated. In
general, there is a correlation between the required compressive force and, the level of post-magnetization stress, the increase in
travel speed and.. View more»
