What Is Silicone Rubber Calendering?

Silicone Rubber Calendering is a mechanical process that continuously feeds silicone rubber or other materials through one or more pairs of heated hard steel rolls, or calenders, to compress and smooth the material and create either uniform standalone sheets or hybrid composites with other materials. Other materials can also be used in the process, such as paper or textiles.

What is the difference between a calender & an extruder?

While calendering equipment may be more expensive than extruders, the process requires minimal cleaning. Extruders, on the other hand, must be purged and cleaned after use. Lgdsilicone Rubber manufactures rubber mixes, molds, extrusions, calenders and covers.

Custom Silicone Rubber Calendering FAQs

Calendering processes rubber by forcing the material softened by heat into the center of two to five counter-rotating rollers. The rollers compact the sheet as it passes through them. The thickness of the resulting product gets determined by the gap between the cylinders, called the nip region.

The uncured silicone HCR preform is typically compressed into a continuous silicone sheet by two or more hardened steel rollers rotating in opposing directions. The silicone may be pressed into a number of substrates, including glass, plastic, release film liners, different textiles, and more.

There are almost endless applications, including:

  • Construction linings
  • Products for interior design, including tablecloths, shower curtains, and coverings for the walls, floors, and ceiling
  • attire, such as waterproof clothing and highly coated protection gear
  • Products for use with food, such as flexible reservoirs and tanks
  • Medical applications for autoclavable items.

Calendering is a mechanical process used to manufacture uniform sheets made of silicone rubber. Raw materials, such as heat cured silicone (HCR) that are heat softened or extruded, are forced through a series of aligned cylindrical rolls that determine the thickness and mechanical properties of the finished products.
