3M™ Bumpon rollstock is continuous urethane sheet stock, supplied with pressure-sensitive adhesive already on the back of the material.
We sell Bumpon rollstock by the yard at iTapeStore, which allows you to cut the bumpers to the dimensions you need for your application. Non-skid feet for an electronics enclosure, spacers between layers of stacked panels, stops for the inside of a cabinet door. You're in charge of the shape.
While molded Bumpons can lock you into certain diameters and heights, rollstock gives you a flat sheet of that same tough urethane which allows you to slit, die-cut, or trim it with a utility knife. That kind of versatility is why product designers, contract manufacturers, and maintenance workers prefer rollstock when the application calls for precision over convenience.
What Is 3M™ Bumpon Rollstock?
Bumpon is the name for 3M™'s portfolio of self-adhesive polyurethane protection products. The rollstock version refers to a continuous-sheet product. In simple terms, it's a roll of tough urethane with a powerful PSA coating laminated to one surface and protected by a release liner.
The polyurethane compound is an elastomer. It absorbs impact, resists abrasion, and stays stable over an extensive temperature range without losing its flexibility. All rollstock SKUs come with the adhesive already applied. Simply peel the backing, press onto a clean surface, and the bond sets.
We carry multiple rollstock series from the 3M™ Bumpon family in both clear and black, in thicknesses from 1/16 inch up to 1/4 inch. The 3M™ Bumpon SJ5616 clear rollstock is suitable in applications with glass and acrylic where visibility matters. The SJ5816 black rollstock and SJ5908 black rollstock cover many general industrial applications.
Rollstock vs. Molded Bumpon Shapes
3M™ offers Bumpon protective solutions in two formats, and the deciding factor is whether you require standard or custom. Molded shapes are individual bumpers such as hemispheres, cylinders, or flat-top discs, on a sheet. Take one off, press on, repeat. They work when you need a familiar shape in moderate quantities with no fabrication.
Rollstock is the raw sheet material on a roll, normally 4.5 or 9 inches wide and up to 72 yards long. You're purchasing polyurethane sheet stock that gets cut into whatever shape and size fits your application best. This is the preferable format when the dimensions of your footprint don't match anything in 3M™'s molded catalog, when you're doing concept development and experimenting with various pad sizes, or when the cost per piece is the deciding factor and purchasing bulk sheet material then manufacturing in-house proves less expensive than pre-molded parts.
For larger-volume operations, the typical approach is to buy rollstock and send it to a die-cutter. Smaller shops buy by the yard and cut on-site with a razor or scissors but both methods work, just at different scales.
Available 3M™ Bumpon Rollstock Products
Not all rollstock is the same thickness, hardness, or color. Here's what sets each series apart:
SJ5616 — Clear Rollstock
Clear polyurethane with acrylic adhesive. Use this one when you need the bumper pad to be practically invisible — glass shelves, display cabinets, transparent acrylic panels. The acrylic adhesive also resists discoloration and yellowing over time, which matters in applications under UV or fluorescent lighting. If the bumper pad is visible to your customers, SJ5616 keeps it discreet.
SJ5816 — Black Rollstock (1/16 inch Thick)
Black polyurethane, natural rubber adhesive, Shore A hardness of 36. The thinnest black option — low-profile anti-skid and surface protection without taking up space. Soft enough to cushion yet thin enough to stay out of the way.
SJ5808 — Black Rollstock (1/8 inch Thick)
Black polyurethane, natural rubber adhesive, Shore M hardness of 72. Twice the thickness of SJ5816, and significantly stiffer. The increased durometer means it can bear larger loads such as equipment feet, spacers between heavy panels, and mounts that need to resist compression from sustained pressure.
SJ5908 — Black Rollstock
Another black polyurethane variant with its own durometer and adhesive pairing. Get in touch for the specific thickness and hardness details on this series.
SJ5832 — Black, Brown, and White Rollstock
Thinnest of all at 0.032 inch (0.8mm), with natural rubber adhesive. Comes in three colors to accommodate applications where even 1/16 inch is too much height. Available in 4.5 inch and 9 inch wide rolls.
We sell every series by the yard and you can buy exactly what you need rather than committing to a full factory roll.
Specifications and Material Properties
Across the Bumpon rollstock family, the core material characteristics hold:
- Base material: Polyurethane elastomer
- Adhesive options: Natural rubber for high initial tack on most surfaces, synthetic rubber, or acrylic for better UV and temperature stability. The series determines which adhesive you get.
- Thickness range: 0.032 inch to 0.250 inch depending on series
- Hardness: Shore M 29 on the softer end up to Shore M 72 on the firmer end. Softer durometers absorb more vibration; firmer ones handle heavier loads without bottoming out.
- Roll widths: 4.5 inch and 9 inch standard
- Surface finish: Matte
- Liner: Translucent polyester film
- Durability: Won't crack, harden, or leave adhesive residue on contact surfaces over time

Applications for 3M™ Bumpon Rollstock
Non-skid fee: Die-cut squares, rectangles, or custom shapes and adhere them to the undersides of equipment housings, electronics enclosures, or benchtop fixtures. The urethane grips hard surfaces without marring them.
Door and drawer stops: A quarter-inch square of rollstock on the interior of a cabinet frame takes the slam out of closing and kills the noise. Thicker SJ5808 at 1/8 inch is worth the additional cushioning on heavier doors.
Cushioning spacers: Place rollstock between stacked circuit boards, glass panels, or machined components during transit or assembly. The material responds to pressure, recovers, and prevents surface contact damage.
Vibration damping: Rollstock placed under motor mounts, compressor feet, or pump bases isolates transmitted vibration. Match the durometer to the load: softer for lighter equipment, Shore M 72 for the heaviest.
Surface protection: Line your assembly jigs, sub-assembly racks, or fixture surfaces with rollstock. This prevents finished parts from acquiring scratches when moved about.
Die-cut gaskets: Rollstock can be die-cut into soft gaskets to block out dust and provide contact sealing where a full environmental seal isn't necessary. It doesn't replace a true environmental seal, but for dust exclusion in junction boxes and enclosures, it does the job.
Frequently Asked Questions
What is 3M™ Bumpon material?
Polyurethane elastomer, a synthetic rubber compound that 3M™ produces for long-term flexibility, resistance to wear, and durability. It does not become brittle or crack the way natural rubber can. All Bumpon products use factory-applied pressure-sensitive adhesive, so there's no separate glue step during installation.
What is 3M™ Bumpon SJ5832?
SJ5832 is a rollstock option at 0.032 inch (0.8mm) thick with natural rubber adhesive. It ships in black, brown, or white, in 4.5 inch and 9 inch wide rolls. Of the Bumpon rollstock range, this is the thinnest pad you can buy and is useful when height constraints are tight.
What is a bumpon?
Bumpon is 3M™'s brand name for their self-adhesive polyurethane protective products. The Bumpon family consists of pre-molded individual shapes (like the small hemispheres or cylinders you may see at the bottom of a laptop), along with the rollstock sheets shown on this page. Same urethane material, same peel-and-stick adhesive, but different form factors.
How do you cut 3M™ Bumpon rollstock?
For small runs and prototypes, a utility knife or rotary cutter on a cutting mat provides clean edges. Production quantities are generally run through a rotary or flatbed die so tolerances are consistent. We sell by the yard so you can buy the amount you need to match your cutting process.
