From Bumper Specialites Inc.
We supply a complete line of moulded, self-adhesive, polyurethane bumpers.
Our Bumpers are 100% Polyurethane. We use no plasticizers, oils or fillers which are widely used in our competitors’ products.
We offer Bumpers with two different Pressure Sensitive Adhesives:
An Aggressive Synthetic Rubber or a High Performance Acrylic to meet your specific requirements.
Custom shapes, sizes, colors and pad configurations are available upon request.

Standard Colors: Clear & Black - Our most popular bumpers! Every bumper is available in Clear and Black. The crystal clear bumper is nearly invisible when used for translucent or see-through applications.
Additional Colors: White, Brown & Gray - Most bumpers are stocked in every color and ready for shipment, however '" colors are inventoried based on popularity. Please call to confirm availability of white, brown and gray. There is no additional charge for clear or pigmented Bumpers.
Custom Shapes & Colors - We are the only company that provides full engineering support to help you design a bumper to meet your particular needs! Our staff will meticulously assist your company with the completion of any project. A onetime charge (this differs with size) for tooling and set-up applies. Your final costlm (m=thousand) will be consistent with our existing line of bumpers. The volume of polyurethane required for custom shapes, difficulty of manufacturing, and normal and customary waste are factors in pricing. You can be assured we are dedicated to providing you with the most competitive prices in the global marketplace!
Special Die-Cut Pads - Available die-cut in strips or smaller pads for a minimal costlm and a one-time tool charge.
NEW Softer Durometer for Sound Dampening - A new softer durometer is offered in two of our standard profiles: BS-1-SD and BS-12-SD. (The -SD suffix designates the softer durometer.) Please call for the availability of other profiles. Not for load bearing applications. See technical information on Page 4.
Application Instructions - To obtain a maximum bond, surfaces need to be smooth, non-porous, clean, dry and free of all debris, oils and solvents. Clean the surface with a low strength solvent such as isopropyl alcohol (rubbing alcohol) or heptane. Follow solvent manufacturer's precautionary warnings and suggested handling procedures when using solvents. Bend pad slightly grasping bumper on sides without touching the adhesive. Apply with enough pressure to ensure a complete bond. Allow a dwell time of 24 hours before exposing to heavy force or weight. The composition of this product contains no migratory plasticizers of any kind, which would mar surfaces of contact. Users should evaluate the suitability of our Bumpers for a specific application under actual conditions.
Tolerances - Our products are manufactured within a tolerance of ~020" (0.5mm). |

Adhesive testing for the acrylic and synthetic rubber was conducted using a polyester carrier. This information is for typical values and is not a specification. End user assumes the responsibility for suitability testing and approval of this products functionality. Adhesives are resistant to water and detergents. Not recommended for use with aliphatic or aromatic hydrocarbons. |
| Polyurethane
The results of the physical test performed on the polyurethane material are summarized in the table below. Please note, these tests were performed on hand mixed samples and the values are averaged. Values obtained from machine mixed samples would be better due to improved mixing and reduction or elimination of entrapped air.
