Precision-Cast Formathane Urethane Sheet (Shore A85)

This Formathane urethane sheet (Shore A85) is used in injection mold tooling as a replaceable wear pad and sliding interface material. Its medium-load design is well suited for contact areas where components experience repeated motion or rubbing, helping protect nearby parts and maintain consistent clearances.

• Wear protection on moving mold components: Fit the sheet as a pad on slide faces, guide contact areas, or auxiliary fixtures to reduce friction-related damage while retaining enough flexibility for stable contact under typical loads.
• Guided retraction/actuation interfaces: Use as a protective barrier in systems that cycle frequently, where predictable cutting/sizing makes it easy to maintain the same functional thickness across rebuilds.
• Industrial press and handling tooling: Apply where medium-load abrasion and contact wear are expected; the sheet format simplifies installation and allows clean trimming for tight fit.

The Shore A85 hardness supports a balance between durability and manageable deflection, making it a practical choice for medium-load wear pads and friction-reduction applications.

Formathane is a precision-cast polyurethane (urethanes) elastomer sheet supplied in the Shore A85 hardness grade, targeted for medium loads and controlled wear. In this hardness range, the material typically offers good abrasion resistance and stable contact behavior, while still allowing workable cutting and trimming during tooling setup.

• Hardness balance: Shore A85 provides a durability/flex trade-off—high enough for wear pad life, but not so hard that it becomes brittle under repeated contact.
• Wear & friction behavior: As a sheet wear pad, it is intended to reduce friction and help protect equipment surfaces in sliding/contact zones.
• Manufacturing: “Precision-cast” indicates casting-based production for consistent thickness and predictable sizing/cutting performance.

No additional heat treatment state (e.g., nitriding, quenching) is specified for this polymer sheet. Compared to harder urethane grades, A85 typically improves conformability; compared to softer grades, it generally improves load-bearing and wear resistance.

Selection starts by matching the sheet’s outer diameter (D) to the protective area you intend to cover. This product is specified with D = 15 in or D = 20 in, so choose the diameter that fully blankets the contact zone with minimal overhang.

• Match cavity/core contact footprint: Determine the circular or near-circular wear interface area in your mold tooling, then select the closest available D that covers the sliding path and contact edges.
• Allow for trimming: Because the sheet is supplied in sheet form and supports clean trimming to fit, you can reduce oversize sections to achieve a controlled contact geometry.
• Fit & tolerance considerations: Maintain consistent positioning to prevent uneven wear. If your tooling requires a specific gap or alignment to maintain actuation clearance, plan trimming so edges do not interfere with moving parts.

All listed dimensions are fixed by the provided D range (15–20 in); trimming is the practical way to adapt the cutout to your mold’s exact wear contour.
