ULTRA BEND®
Ultrafab’s ULTRA BEND® offers OEMs and engineers a competitive advantage for products that require specific sealing solutions. The flex-back design also features an extremely dense, tight polypropylene fiber configuration that creates uniform density distribution.
Features & Benefits
Sealing Applications
Ultrafab’s ULTRA BEND® provides superior sealing advantages to a large variety of applications including window & door, HVAC, lighting, medical imaging, and printing/kiosk. Below are some practical examples of how it can benefit specific applications.
Increase Vinyl Window Lifespan
During the sliding process, a rigid-back plug is vulnerable to getting snapped off or caught due to irregular surfaces created by heat-welded seams on vinyl windows. The ULTRA BEND® is able to flexibly adhere to these irregular surfaces. This means the dust plug is less likely to get knocked off and will provide a longer lifespan.
Reduce Spindle Friction up to 360º
Spindles, or any component that turns up to 360º, can lead to production damage without protective fibers. ULTRA BEND® is able to wrap around spindles to provide 360º of friction reduction, no matter which direction the component turns. An example of this application is an automated manufacturing process where components run down an assembly line. In order to maintain aesthetics, ULTRA BEND® can be used to prevent product surface markings as components are guided through the assembly process.
Reduce Vibration on Radius Windows
Enclosures with radius contours, such as the sliding half-moon enclosures seen on modern boats, present a unique sealing challenge due to angles that aren’t restricted to 90º. Our flex-back product can be dropped into the bottom of that channel and give the sliding window a continuous contact area throughout the internal perimeter. When used in conjunction with other seals, this reduces vibration and creates a barrier against air and water infiltration.
Sealing Advantages
- Reduces or eliminates air/water infiltration, sound/vibration, and operational force
- Fits uneven surfaces (e.g., welded corners, pockets) due to flexible base
- Fits securely and eliminates “rise” that could occur with rigid-based plugs due to flexible base combined with superior adhesive options
- Provides industry leading durability and longevity with ultrasonically welded polypropylene filament assembly
- Provides ability to wrap sealing function around perimeter, corners, radius, and other difficult to seal areas
