Bumper protectors are strong, flexible & highly resilient. Among their many features is the ability to withstand shock

and vibration, whilst being both non-slip and non-marking.

Bumper protectors are supplied kiss-cut on a sheet to allow ease of removal and aid application. Manufacturing so

many different shapes, colours and styles, the standard quantity on a sheet will always vary depending on the size of

the part. Information on this and the number of sheets and pieces in our cartons can be found in the product pages on

our website.

Exposure to the Environment Bumpers are intended for interior applications where physical properties will remain unchanged. When used

externally for extended periods, some discolouration as well as loss of adhesion may occur.

In the event bumper protectors are used for applications involving the support of heavy plate glass or similar, laboratory tests have

shown that cylindrical shapes perform better than hemispherical.

A heavy load supported by the wrong style of bumper protector could result in fracturing or "crumbling" of the polyurethane

material. Please refer to the chart for weight loading guidance.

Compression tests were carried out at ambient temperature (24ºC)

Standard Bumper Protectors Pressure Sensitive adhesive data Acrylic Adhesive Rubber Adhesive The acrylic adhesive is a medium tack adhesive with higher end use temperature and good clarity. Usually preferred for applications where good ageing properties are required. Unless otherwise requested this adhesive is standard on all clear bumper protectors because of its superior ageing properties.

Standard Bumper Protectors Temperature Data (Application) Usual application temperature advised for pressure sensitive adhesives are 18-30°C. We do not advise application at higher temperature Concerning lowest temperature, test have been carried out to evaluate the impact of lower temperature on initial adhesion. Indeed, the major risk is a lack of adhesion when temperature decreases.
