Silicone Rollers Able to perform well at temperatures as high as 500º F (260º C), silicone rollers and rolls offer high resistance to ozone and chemicals as well as being generally stable and non-reactive. However, silicone rollers are not typically used in situations requiring great tensile strength.

Additional industries that utilize silicone rollers include mining, commercial, marine and mail handling. Ideal for peripheral decorating, other beneficial characteristics of silicone rollers include great resilience, ability to strongly adhere to metals, low tack, low compression set and the ability to conform well to surface variations.

Silicone rollers are manufactured in the same two methods of other types of rubber rolls: injection molding and compression molding. However, silicone differs since it is not a true rubber, and the difference is most apparent in its liquid state. More commonly injection molded, liquid silicone is injected using a unique type of injection molding referred to as liquid injection molding (LIM). This process involves proportioning, mixing and dispensing of the two components of liquid silicone rubber, which are the heat-cured liquid silicone rubber and a catalyst, which is typically platinum.

Since it is not very viscous, liquid silicone rubber is pumped through pipes or tubes to the vulcanization equipment. There, the two components are mixed in a static mixer until a single homogeneous material is achieved. Then the homogeneous mixture is transferred to the cooled metering section of the LIM equipment where the liquid silicone rubber compound is pushed through cooling sprue and runner systems into a heated cavity in which the vulcanization occurs.

For compression molding, the liquid silicon rubber is injected into an open mold, which is closed with pressure that forces the liquid silicone rubber to solidify in the mold. Silicone rollers often consist of a silicone layer of rubber that has been bonded to a metal core, typically aluminum or steel.
