Rubber Friction Coefficient vs. Durometer - 65 duro vs. 85 duro

Rubber Friction Coefficient vs. Durometer - 65 duro vs. 85 duro

(OP)
Eng-tips members,

I have measured friction coefficient of 85 duro mixed rubber compound with no waxes or lubricants on smooth steel - the result is roughly 0.5. I would like extrapolate that data to 60 duro friction same basic rubber compound and same substrate.

Thanks,

Jeff C.

RE: Rubber Friction Coefficient vs. Durometer - 65 duro vs. 85 duro

Sir,
by reducing hardness you will get higher co.of friction.
you can use graphite powder that give you low co.of friction.
or you can use Teflon powder to reduce value of friction.
also you can reduce filler to lower compound hardness and use graphite power or Teflon powder.

RE: Rubber Friction Coefficient vs. Durometer - 65 duro vs. 85 duro

I assume its a rolling friction coefficient (not starting or sliding)- the OP is obviously only concerned with a correlation not achieving a certain amount of friction.
