3M SJ5816

Main features

  • Die-Cut Protective Conversion
  • 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.

Mechanical Properties
Elongation
Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.

Thermal Properties
UL 94 Rating
Flammability rating classification. It determines how fast a material burns or extinguishes once it is ignited. HB: slow burning on a horizontal specimen; burning rate less than 76 mm/min for thickness less than 3 mm or burning stops before 100 mm V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed. V-1: burning stops within 30 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed. V-0: burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed. 5VB: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may develop a hole. 5VA: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole

Electrical Properties
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material. Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property. As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
7.87 kV/mm
