Vacuum Static Cast Polyurethane System
One of the many things that set Imperial apart from the crowd is our ability to develop new products that meet customers’ most demanding quality specifications. An example is our ability to deliver high performance vacuum-static cast polyurethanes
What are Polyurethane Rollers?
- Rollers made of cast polyurethane
Who this is for:
- Paper, film and foil coaters and laminators
- Tissue and towel embossing lines
- Corrugated box and folding carton plants
- Wood and lumber processing lines
- Steel, aluminum and red-metals processing lines
- Rotogravure printers
- Offset printers
What problem this solves:
- Dramatic increase in roll life compared with conventional urethanes and rubber
- Can deliver a more precise film in certain coating applications
- Exceptional cut resistance in harder durometers
- Better vibration dampening than rubber
- Abrasion resistance that exceeds almost all rubber compounds
- Folder split nips that outperform other products with our “gapless” technology
Why this is special:
- Fewer roll changes reducing downtime
- Better coating laydown across the web, strip or sheet
- Sharp edges of metal or wood cause less wear or roll damage
- Roll shape is maintained longer, reducing frequency of roll changes
- Commercial printers using split nips receive an immediate performance increase
Availability, and when it can be delivered:
- Standard product; a wide inventory of molds provides flexibility to meet your scheduling needs
- Emergency services available
Comparison to competitive products:
- Imperial Rubber designs its own urethane formulas to suit your application
