High Hardness Soft Sponge Foam Interface Cushion Pad

High Hardness Soft Sponge Foam Interface Cushion Pad: Balance Hardness & Softness for Precision Sanding & Protection 
Are you struggling with interface pads that are too soft or too hard? Our High Hardness Soft Sponge Foam Interface Cushion Pad solves these pain points—crafted with high-density polyurethane foam and a flexible, shock-absorbing structure, it balances rigid support for uniform sanding and soft resilience for surface protection. Ideal for pairing with sanding discs in automotive refinishing, woodworking, and furniture polishing, it’s the key to achieving smooth, scratch-free results while extending sandpaper life. 

Core Features: Hardness & Softness in One Pad 
The pad’s performance lies in its unique foam structure and material design, which addresses the contradictions between "precision sanding" and "surface protection": 
Controlled High Hardness: Made of high-density polyurethane foam with a Shore hardness of 40-60D—hard enough to maintain shape under sanding pressure, yet soft enough to conform to slight curves. Unlike low-hardness pads that sink and cause inconsistent sanding, this pad ensures the sanding disc stays flat and contacts the workpiece evenly, reducing the need for rework. 
Shock-Absorbing Soft Resilience: The foam’s closed-cell structure has excellent elastic recovery—when pressed during sanding, it absorbs 60%-70% of the vibration from electric sanders. This not only reduces hand fatigue for operators but also prevents "sanding marks" caused by sander vibration, especially critical for delicate surfaces like piano finishes or automotive clear coats. 
Hook-Loop/Adhesive Compatibility: The pad’s surface is treated with a wear-resistant coating that works seamlessly with both hook-loop sanding discs (easy to replace) and adhesive sanding discs. The coating also resists dust and sandpaper abrasion, ensuring the pad’s surface remains smooth even after 500+ hours of use. 
Temperature & Chemical Resistance: The high-density polyurethane foam is resistant to heat generated during prolonged sanding and common solvents. This prevents foam deformation and ensures stable performance, even in high-intensity scenarios like automotive body sanding.
