Learn more about our rollers, benefits and applications.
Market-Leading Roller Range
United Silicone provides silicone rubber rollers with a market-leading silicone-to-metal bond. We also lead the market in size range with diameters up to 20 inches and face lengths up to 110 inches.
We provide complete rollers (core plus coverings) along with roller re-coats to create rollers that work on our systems as well as competitor systems.
Benefits
Market-Leading Size Range, Repeatability and Adhesion
| Benefit | Description |
| Market-Leading Adhesion | Proprietary system for chemically bonding silicone to metal cores provides market-leading adhesion without the need for messy adhesives |
| Superior Repeatability | Each roller is surface ground, ensuring precise TIR and OD measurements as well as a smooth, surface finish. |
| Seamless Finish | Manufacturing process eliminates the appearance of a ‘meeting point’ common in competitive production processes resulting in blemish-free contact and heat transfer for your applications. |
| Fast Turnaround | Often in 7-10 days if not faster. |
Applications
The many benefits of silicone rubber rollers make them well-suited for a wide variety of applications. Silicone conforms readily to surface variations ensuring smooth seal application without air entrapment. Our silicone rollers are used for sealing and film feeding in rigid and flexible packaging applications.
