resilon™

Light-weight, robust polymer springs are replacing steel coil springs in a range of energy management applications including track tensioners for light-duty mobile equipment such as skid loaders.

With safety as Priority #1, use of polymer springs eliminates a potential source of injury and safeguards workers during equipment assembly and installation. Polymer springs are much safer to install compared to steel coil springs because their lowered stored energy reduces the risk of injury and damage due to uncontrolled release.

Product Features:

• Safer. Lower stored energy vs. steel coil spring reduces risk of uncontrolled release
• Smaller. For a given spring force, up to 75% reduction in space allows simple fixturing and assembly
• Lighter. Up to 90% reduction in weight for a given spring force gives  equipment designers more degrees of freedom in weight distribution

The Engineered Polymer Systems Division of Parker Hannifin Corporation, the global leader in motion and control technologies, has launched a new material, Resilon® 4350 Polyurethane, delivering unmatched high temperature seal performance and reliability for a wide range of applications. This new material extends the high temperature sealing range of polyurethanes by over 20°F.

Parker’s Resilon Polyurethane is the established industry leader in high performance hydraulic sealing systems.  This newest addition, Resilon 4350, increases the high temperature operating window from 230°F to 250°F for continuous use in many applications while other critical performance attributes such as wear resistance, extrusion resistance, glass transition temperature, and rebound remain best in class.   All of this adds up to a new solution for seal designers as they push the envelope in temperature extremes.

Reliable Solutions:

Parker’s combination of advanced seal design technology and material expertise has produced a reliable zero-leak rod seal package for hydraulic cylinders for greater equipment output which:

• Extends useful cylinder life
• Maximizes equipment uptime
• Extends maintenance intervals

Integral to the design of the zero leak seal package are the characteristics of Parker’s Resilon™ polyurethane material – designed for extended temperature range, wear resistance, compression set resistance, and overall toughness.
