SFX Heatwave

Raffir Heatwave are four new special effect colors that are now also available in the Raffir Metapol series. They have the same physical properties as the other Metapol products. However, they are special in their ability to change color depending on temperature.

All four Heatwave colors are dark at temperatures below 28C (82F). Meanwhile, they turn respectively bright blue, green, yellow or red at higher temperatures. Furthermore, all four thermo-sensitive colors are available in three different Metapol types as illustrated on the blocks below. Their upper halves are dark, because they are cold. While their lower halves are bright colored, because they are hot.
This ability to change color can be used functionally to indicate whether a finished product is hot or cold. Alternatively, it can simply serve as a visual effect that it changes color in use.

The material has a maximum recommended working temperature of 60C (140F). Standard handle blocks dimensions are 120*40*25mm, but custom sizes are also available.
