Product selection help

any different tapes are on the market, with estimates ranging form 200 to 400 different varieties. Tapes may be classified according to construction, function or to use. According their construction they may be subdivided into the following categories: fabric tapes, paper tapes, film tapes, foil tapes, non woven fabric tapes, reinforced tapes, foam tapes, double-face tapes and transfer tapes. As is obvious form the preceding list, the backing, rather than the adhesive provides the main distinction among various tapes. So the PSA tapes consist of two components: Backing and Adhesive. The purpose of the adhesive is to secure the backing to another surface in order to perform some function; Very important and mostly decisive for the right choice is to know the properties of the available backings, not only their advantages but also their disadvantages.

It is therefore that Carlisle Hardcast Europe B.V. offers the customer a selection guide with various backings in combination with a rubber adhesive.
