(1) Silicone Rubber Viscosity
Silicone rubber viscosity refers to the volumetric property of a liquid, quasi-liquid, or quasi-solid substance that resists flow, that is, the internal friction or flow internal resistance exhibited between molecules when flowing under external force. Generally, silicone rubber viscosity is directly proportional to silicone rubber hardness.
(2) Silicone Rubber Hardness
Silicone rubber hardness refers to the ability of a silicone rubber material to locally resist the indentation of a hard object into its surface.
Silicone rubber has a Shore hardness range of 10 to 80, giving designers ample freedom to choose the required hardness to optimally achieve specific functions.
Mixing different proportions of polymer matrix, fillers, and additives can achieve various intermediate hardness values.
Similarly, the time and temperature of heat curing can also change the hardness without compromising other physical characteristics.
