Nowadays, people pay more and more attention to self-health. Therefore, environmental building insulation materials are highly required, Under this background, Greenthermal was naturally generated. Greenthermal series products are technically based on cross-linked polyolefin polymer compounds. Compared with other insulation materials, this odorless cross-linked polyolefin is more stable in chemical properties and won’t easily get decomposed. At the same time, it is waterproof and low thermal conductivity which makes it an excellent environmental energy-saving material.
