The coefficient of friction of silicone rubber ranges from less than 0 25 to more than 0 75.
F f μ n 1.
Lower durometers have higher coefficients.
The force it takes to initiate movement between the silicone rubber and a steel panel static cof was measured as well as the force needed to keep the silicone rubber moving against.
Non coated silicone samples are compared side by side.
Values outside this range are rarer but teflon for example can have a coefficient as low as 0 04.
Nusil technology experts recently conducted a study to evaluate the static and kinetic coefficient of friction of coated versus non coated silicone surfaces.

Silicone is naturally quite tacky with a coefficient of friction of approximately 1 0 in many cases.
For example static friction can prevent an object from sliding down a sloped surface.
N normal force between the surfaces n lb there are at least two types of friction forces.
Static friction is friction between two or more solid objects that are not moving relative to each other.
50 decrease in the coefficient of friction when coated silicone samples vs.
The rubber static friction coefficient μ s contributes e g to the grip of tyres shoes and windshield wipers even though research is often focused on the sliding dynamic friction coefficient μ d the μ s is not purely a material property of contacting surfaces because it depends on the load temperature loading conditions and lubrication 1 2 3.
A value of zero would mean no friction at all an elusive property.
