​Exploring Silicone Calendering

Posted

Silicone products for your industry!

Flex Technologies is known for the high-quality silicone hoses we produce, but we also offer a myriad of capabilities that industries can readily take advantage of. If you’re developing a product or innovating a process, silicone calendering may help elevate its application.

Are you an industry that could benefit from swapping out traditional rubber products to silicone? Flex Technologies is a solution-based company that can help you solve concerns or opportunities your industry may face. Learn more about the role of silicone calendering in today’s post.

What Is Silicone Calendering?

Silicone calendering is a mechanical process that utilizes large rollers to press silicone into sheets that can be used in textiles, most commonly in fabric, cloth, cord, etc.

If you’re not familiar with silicone calendering, the fabrication process creates a different silicone product that is widely used today.

These heavy-duty rollers — typically consisting of two or more — create silicone sheets that run either vertical or horizontal, depending on their purpose. Different types of silicone calendering include steel cord calendering and fabric calendering. Within these types, you have fabric inserted processing or unsupported.

Silicone Calendering Applications

Calendering silicone can improve your industry’s products or processes, transforming production and providing you an innovative edge in business.

Frictioning

Frictioning establishes a premier adhesiveness where silicone is forced into the fabric weave. A three-roll calendering machine is used because the top and bottom rolls run at a much lower speed than the middle, promoting versatile speed intervals needed to create this specialized silicone material.

Topping (Skim Coating)

The topping process creates a well-fortified material where silicone is coated on both sides of the material, thus strengthening the material. A three- or four-roll calender is used in the topping process.

Profile & Embossing

Material embossing calendering is most notably seen in tire treads and as the tread in footwear. This type of calendering creates patterns on the material sheet producing embossed or profiled treads.

Rolling

For a continuous sheet of silicone with a thickness of 3 to 4 millimeters, a two-roll calender can produce just that.
