Simulation experiment on Biofi toothbrush bristles
In order to promote the environmental toothbrush production, Tai Hing successfully has developed Biofil bio-degradable toothbrush filament, which is made from new environmental raw material.
In order to simulate the real brushing process better, we choose plasticine to substitute for our gum.
Next, putting Biofil and conventional toothbrush bristles on the plasticine surface. Both kinds of toothbrush filaments are used to rub the plasticine surface back and forth several times with the same force in one minute.
We find that conventional toothbrush bristle leaves more scratches than Biofil on the plasticine surface in the test.
