- Skid-Resistant Polyurethane Cushioning
- High-Tack PSA Installation
Product Description
3M Bumpon Resilient Rollstock SJ5816 is a black, self-adhesive solid polyurethane rollstock for conversion into die-cut feet, stops, spacers, and cushioning parts. The 1.6 mm sheet combines Shore M 72 polyurethane with an R-30 natural-rubber pressure-sensitive adhesive and PET release liner. Its resilient, skid-resistant surface is used to reduce vibration and noise, cushion components, and protect finished surfaces from scratching or marring. The roll format supports custom shapes and sizes, while the pressure-sensitive backing simplifies placement after die cutting. SJ5816 is intended primarily for interior applications; protected outdoor use may show discoloration or chalking.
Key features
- Die-cut rollstock conversion: Converts into custom feet, stops, spacers, gaskets, and protective shapes.
- Skid-resistant cushioning: Solid polyurethane provides grip, cushioning, and vibration or noise damping in compact assemblies.
- Natural-rubber PSA mounting: R-30 adhesive provides high initial tack for pressure-sensitive placement after conversion.
Applications
Applications include die-cut protective feet, stops, spacers, gaskets, anti-rattle parts, cushioning elements, and non-scratch surface protection.
