Considering the poor wet-skid resistance (WSR) and facile abscission of natural rubber (NR) when applied in ligation band

a new ligation rubber ring based on NR was prepared when used fumed silica as reinforcing agent and glycerol-gelatin as processing agent

which met with the application of ligation bands in mechanical property. Meanwhile

the property of WSR of the ligation rubber ring was characterized by stress

stress relaxation

surface roughness

micro-hardness and dynamic viscoelasticity. The results showed that the stretching stress of NR on 500% was 6.12 MPa

surface micro-roughness (Ra) was 9.754

and excellent micro-hardness and tand. Besides

the coefficient of maximum static friction on wet surface was 2.6. All above results indicated that a good wet-skid resistance was obtained in the new ligation rubber ring.
