Silicone rubber rollers are known for their excellent heat resistance, ozone resistance, chemical inertness, and non-stick properties to plastics. They are widely used in the processing of hot-adhesive products such as polyethylene calendering, embossing, printing, and dyeing of films and fabrics. These rollers also play a key role in plastic compounding, corona treatment, and other machinery, as well as in the production of release rolls and nonwovens on sugar production and packaging machines.

Overview of Silicone Rollers
Silicone rubber rollers are highly valued for their heat resistance, ozone resistance, chemical inertness, and non-adhesive characteristics. They are commonly used in the processing of hot-adhesive materials like polyethylene calendering, embossing, printing, and dyeing of films and textiles. Additionally, they are essential in plastic compounding, corona treatment, and in the production of release rolls and nonwovens on sugar and packaging machines.
In general, a silicone roller refers to a rubber roller used in heat transfer machines, specifically designed for pattern printing in thermal transfer processes. These are often used in the production of toys, electronics, craft gifts, and hot stamping products.
Materials Used in Silicone Rollers
Silicone rollers are made from high-quality imported liquid silicone, particularly high-tear-resistant silicone rubber. They are molded under controlled temperature and dust-free conditions, resulting in a seamless surface that is heat-resistant, non-sticky, and offers superior release properties compared to solid silicone rollers. Some manufacturers can add silicon carbide based on customer requirements to achieve a more brilliant finish. These rollers are widely used in the plastics industry, especially in high-end calenders and casting machines.
Types of Silicone Rollers
- **Electromagnetic Silicone Roller**: Designed for BOPP corona treatment, it is specifically matched with German BRUCKNER BOPP film units.
- **Hot Stamping Silicone Roller**: Used for sheet and paper stamping, such as corner board and bronzing paper.
- **Foamed Silicone Roller**: With a hardness range of 10–30 Shore A, this high-elastic, high-temperature resistant product is suitable for professional printers and washing equipment.
- **Falling Sand Silica Gel Roller**: Combines French fine diamond technology with silica gel to create both glossy and matte effects.
