Abstract
The invention relates to a heat-shrinkable article that is at least partially coated with a temperature indicator. This temperature indicator is composed of an organic polymer having a suitable bonding agent, whereby the organic polymer is contained therein in a finely ground condition. As a result of this condition, the appearance of the agent is opaque and has a color corresponding to the degree of granulation and material constituent. When the melting point of the composition is reached, the material melts and becomes transparent or at least translucent. The color of the article shows through, so that this color change can be interpreted as a temperature indication.
