CrodaTherm™ 21

CrodaTherm 21 is a readily biodegradable phase change material used in temperature controlled packaging and thermal energy storage applications. It can protect goods in specalised thermal shipping containers, and can increase the efficiency of HVAC applications, which are often very energy intensive. CrodaTherm 21 is a sustainable and non-corrosive alternative to more hazardous paraffins and salt hydrate PCMs on the market.
