UT Type Heavy-Load Urethane Sheets (Shore A90) Sheet

This UT type heavy-load urethane sheet is used in injection mold tooling as a cushioning and wear interface component where mechanical contact, vibration, and repeated impacts occur. Its Shore A90 elastomer balance helps absorb shock while maintaining reasonable stiffness for stable fixture behavior.

• Vibration damping pads: Place between mounting surfaces or on tooling plates to reduce machine-induced vibration. The sheet format allows cutting to match the contact footprint.
• Protective wear pads: Use as a replaceable liner at guides, stops, or sliding contact zones to limit abrasion and prolong wear life.
• Handling system cushioning: Install in end-effector tooling or transfer fixtures to soften contact loads during part present/release cycles, improving consistency without rigid impact.

Because this is supplied as a sheet (not a molded component), you can tailor thickness and surface coverage to your mold support hardware while retaining the elastomer behavior expected from a Shore A90 formulation.

The product is an urethane elastomer sheet in the UT type heavy-load class with Shore A90, targeting a practical trade-off between impact resistance and abrasion/wear resistance. Shore A90 indicates a harder rubber-like material than softer cushioning grades, which typically improves load-bearing stiffness and reduces creep under sustained compression.

• Wear & cushioning balance: Suitable where you need abrasion resistance but still require elastic energy absorption.
• Toughness trade-off: Compared with softer Shore A grades, higher hardness generally reduces deflection; this can be beneficial for dimensional stability in fixture interfaces.
• Manufacturing state: As a sheet elastomer, the performance is inherent to the supplied cured urethane formulation; it is typically cut/laminated for tooling use rather than heat-treated like steel inserts.

No steel grade or HRC heat-treatment data applies to this urethane sheet product variant.

Selection is driven by the provided sheet geometry. Choose Height/Thickness (T) in the range 1 ~ 50 mm based on required deflection and contact stress. For coverage, select Width (A) from the available options: 500 mm or 300 mm.

• Match contact compression: Use a thicker T when you need more load capacity and longer wear surface; use thinner T for tighter space constraints.
• Fit to cavity/core interface: Cut the sheet to the tooling footprint of the press plate, guide contact zone, or protective liner area, ensuring full support under the contact patch.
• Tolerance/fit: Because this is a sheet elastomer, plan for cutting tolerances and verify clearance after machining/cutting. Avoid over-compression—target a controlled squeeze consistent with your fixture design.
• Configurable vs fixed: Width is fixed to 300 or 500 mm options, while thickness is configurable across 1–50 mm for your cushioning requirement.
