Product Overview

The Critical Barrier for Quality Treatment

In any corona treatment system, the silicone sleeve acts as the vital dielectric barrier between the high-voltage electrode and the ground roller. A compromised sleeve leads to pinholes, uneven treatment, and costly downtime.

Anjali Corporation offers industrial-grade silicone sleeves manufactured from 100% pure silicone rubber, designed specifically to withstand the harsh environment of continuous high-voltage discharge and ozone exposure found in extrusion and converting lines.

Superior Dielectric Strength: Withstands high voltage (up to 20kV/mm) without puncturing, preventing arcing and roller damage.
High Thermal Resistance: Operates efficiently in temperatures ranging from -50°C to +250°C, making it ideal for high-speed lines that generate significant heat.
Ozone & UV Resistant: Specially formulated to resist degradation caused by the ozone generated during the corona discharge process.
Seamless Finish: Extruded with a smooth, seamless surface to ensure uniform film contact and consistent dyne levels across the web.
Flexibility & Durability: Retains elasticity over time, resisting hardening or cracking even under continuous mechanical stress.

Where are Anjali Silicone Sleeves Used?

Our sleeves are compatible with most major brands of corona treaters and are essential for:

Blown Film Extrusion Lines: Protecting the treater roller during the production of LDPE, HDPE, and PP films.
Converting & Laminating Machines: Ensuring the backup roller remains insulated during secondary treatment.
Printing Presses: Used on nip rollers and treater rollers in Flexo and Rotogravure presses.

Maximize the Lifespan of Your Sleeve:

Clean the Roller: Ensure the metal roller is free of old adhesive, dust, or rust before installation.
Use Air Assist: Use an air nozzle to expand the sleeve slightly while sliding it onto the roller to prevent tearing.
Check for Trapped Air: Ensure there are no air bubbles trapped between the roller and the sleeve, as this can cause hot spots and premature failure.
Regular Inspection: Rotate the sleeve periodically if possible and inspect for carbon tracking or pinholes.

Great technical descriptions of the machines and treatment process. The product brochure link is helpful. Still, the overall design feels a bit basic — improved layout and images could make the browsing experience better.”

The website has all key business info and product lists available, but navigating between pages isn’t immediately intuitive. More clear menus and responsiveness on mobile would improve usability.

The site provides solid information about Corona Treater systems and their applications, and contact details are easy to find. However, some sections feel dated and could benefit from more modern visuals and updated content.
