New thermoplastic colour compounds have been recently launched, which change colour when exposed to body heat (31°C) or higher temperatures (45°C). Customers have the option of choosing the colours both before and after exposure to heat. These compounds are made by adding thermochromic pigments to low-temperature resins such as polypropylene or thermoplastic elastomers. The new thermochromic compounds provide an indicator of how hot a given object is once the activation temperature is reached. These new thermochromic compounds are particularly well suited to applications where heat-induced colour change can be an added safety feature. Products such as infant feeding spoons, automotive radiator shrouds and medical devices are particularly expected to benefit from these new compounds. In the case of radiator shrouds, the idea would be to in-mould the word "hot" into the shroud which would turn red when the water inside would begin to heat up. Asia is expected to have good potential for these colour changing compounds in the areas of medical, small appliances, automotive, besides the general consumer markets.
