New material type - LUMI ("white") - not painted by titanium-dioxide, but natural snow-white color is one of the polymer characteristic....in addition, material is very hydrophobic, recyclable, and easier to clean...testing ongoing...
Even LUMI (Finnish word for "snow"), starting to melt above 0C, this LUMI (translated as "white") needs far above 100C to start melting.
