A calendar machine is a mechanical device that is used in the manufacturing of sheet material. A calendar may be used to make sheet from a ranges of substrates including paper, cloth, and raw rubber. In sheet rubber manufacturing, the rubber compound passes between two or more parallel counter rolling rolls in a controlled environment. The calendar provides the dimensionality to the rubber compound by controlling the thickness gauge and width.
Carbon Black is a material of partial (incomplete) combustion or thermal decomposition of hydrocarbons. It is essentially elemental carbon in the form of extremely fine particles having an amorphous molecular structure. Rubber grade carbon blacks are characterized by four basic properties: surface area, particle size, structure and surface activity. These properties of carbon black effect on rubber properties. Carbon black is one of the major fillers used in rubber production as pigments, reinforcements and to meet specific requirements.
Provides added cushioning to steady material flows and conveyors. Also prevents damage or build up of material along the chute over time.
Fabric re-enforced sheet rubber enhances dimensional stability and is typically used in applications with high compression loads.
A polymer made of two different monomers. For example, SBR is a rubber co-polymer and is made up of the monomers Styrene and Butadiene.

Intimate mixture of a polymer(s) with all materials necessary (oil, carbon black, curatives, etc.) for the finished article.
A press (commonly hydraulic press) that molds and laminates material into a desired three-dimensional shape. Learn more about WARCO BILTRITE’s Molded Rubber Capabilities
The decrease in thickness of a test specimen 30 minutes after removal from a device in which the specimen has been subjected to compression deformation.
The condition where a shaped article is processed through vulcanization reaction without pause. Microwave cure is one example of continuous vulcanization.
An irreversible process during which a rubber compound through a change in its chemical structure (cross–linking, for example), becomes less plastic and more resistant to swelling by organic liquids and elastic properties are conferred, improved or extended over a greater range of temperature. Cure and vulcanization are interchangeable terms as they share the same definition.
