In the United Kingdom in March 2008, 20,000 numbered packs of pink Blu Tack were made available, to help raise money for Breast Cancer Campaign, with 10 pence from each pack going to the charity. Originally Blu Tack was white, but consumer research showed fears that children may mistake it for chewing gum, so a blue colouring was added. While the inventor of the commercially released Bostik product is unknown, a precursor product to Blu Tack was created by a sealant developer around 1970, as an accidental by-product of an attempt to develop a new sealant using chalk powder, rubber and oil. Īs of 2015, Bostik was manufacturing around 100 tonnes of Blu Tack weekly at its Leicester factory. The material is not flammable, but emits carbon dioxide and carbon monoxide when exposed to fire or high temperatures. It is non-soluble and is denser than water. It can be swallowed without harm and is not carcinogenic. The composition is described as a synthetic rubber compound without hazardous properties under normal conditions. The spelling now used is without a hyphen. Generic versions of the product are also available from other manufacturers. Traditionally blue, it is also available in other colours. Blu Tack is a reusable putty-like pressure-sensitive adhesive produced by Bostik, commonly used to attach lightweight objects (such as posters or sheets of paper) to walls, doors or other dry surfaces.
