PureHT™

Born from a five-year collaboration between Siser and the University of Biotechnology – Padua, Italy, PureHT™ represents a paradigm shift in the heat transfer materials industry. While conventional materials may take upwards of 20 years to break down, PureHT™ naturally decomposes within just 6 months, without releasing any harmful toxins or leaving micro plastics in the soil. When paired with ethically made natural textiles, PureHT™ is a conscious way to begin redefining industry standards.
