2 We explain some of the terms used in this guide: Adhesion strength Determines the strength of the bond between a tape and the applied surface. Adhesion strength is measured in N/cm. Elongation at break A measure of how much a tape can be stretched until just before its breaking point. Some tapes with a crepe or wrinkled backing may allow greater stretch. Tensile strength The force required to break a tape. This property is measured by taking a piece of tape, applying a pulling force and measuring the tension applied in N/cm. Conductivity For metal tapes, we specify whether the tape is conductive. This determines its usability for applications such as cable shielding applications. Operating temperature Indicates the ideal temperature parameters in which the backing and adhesive components of the tape will perform to a pre-determined specification. Operating outside of these limits will degrade a tape'

s performance. Foam density Density is measured by taking a sample of known dimensions and weight, and then dividing weight by the cubic volume. The following materials are used as adhesives in our tapes: Acrylic An adhesive that can have a low initial bond or '

tack'

, but is still excellent for outdoor sealing work. It has good resistance to varying temperatures, chemicals and UV light. Acrylic displays a good intimate contact with the substrate and is slow drying. Silicone An adhesive of high flexibility able to work in a wide temperature range. Silicones display excellent ageing characteristics and have a good resistance to solvents. Rubber Rubber has a very special chemical structure, and, mixed with a resin, is an extremely adhesive component. Displaying a high initial tack, higher shear strength and limited UV resistance, rubber can be used for ducting and surface protection work. Thermosetting acrylic Displaying a higher level of bond under stress, thermosetting an acrylic adhesive causes it to '

set'

. It remains in this state even during subsequent temperature variations. Acrylate A type of adhesive material found on some, e.g. copper sealing, tapes. It is especially resistant to UV, variable weather solvents and plasticisers. Acrylate has a high ageing ability.
