Uncured rubber deforms easily when it is warm and is brittle when cold. In its natural state, it does not exhibit the properties that make it a flexible, valuable material for many finished products. Curing, also known as vulcanization, causes the long polymer chains that rubber is composed of to become crosslinked. This prevents the chains from moving independently, allowing the material to stretch under stress and then return to its original shape when the stress is released. The different curing methods available involve heating the rubber after a curing additive has been added to the compound. Kismet's rubber vulcanizing capabilities also include the vulcanization methods, listed below.

Rubber Vulcanizing & Vulcanization Methods

The curing methods Kismet offers are:

  • Continuous cure – Used for continuous processing operations, microwave curing and salt curing provide vulcanization for rubber compounds that are electrically conductive. The microwave cures the rubber from the inside out, curing the rubber quickly and evenly. Salt is excellent for curing due to its relatively short-length curing units. Salt bath curing has good heat exchange properties and can be used at extremely high temperatures.
  • HAV systems – Hot air vulcanization is a continuous process that provides uniform curing at high production speeds. The continuous circulation of hot, damp air over the parts provides fast, complete vulcanization. HAV is recommended for many modern rubber compounds, as well as silicone.
  • Steam Cure – Autoclave (steam) curing is used for discontinuous processing operations. It is used for large extruded and hand-built products, involves manual processing.

Microwave and HAV systems allow for tighter tolerances and the manufacture of longer-length parts in a fast production operation. Microwave and HAV systems can also be done on complex profiles.

At Kismet Rubber, we understand that the quality of your finished product is dependent on the quality of the components you use. We are committed to manufacturing your part to the highest standard of excellence so you can be assured that your Kismet component will meet or exceed your expectations.
