Abstract: An electrical cable or an optical cable, which has a core with a cladding. An imprint is on the cladding and has the imprint formed by a plastic powder which contains copolymers of ethylene with unpolar comonomers.

Abstract: A shrinkable composite section is formed from a shrinkable composite foil composed of at least two shrinkable planar foils adhering firmly to one another. Each of the two shrinkable foils has a shrink direction proceeding at a suitable offset angle relative to the shrink direction of the other individual planar foil so that the resulting overall shrink direction occurring for the composite foil extends between the shrink directions of the two individual foils. The tendency toward tearing or, respectively, continued tearing of the shrinkable composite foil section is, thus, diminished.

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.
