Hard polyurethane (PUR)

Rigid polyurethane (PUR) is a low-temperature insulation material formed by chemical reaction through mixing and stirring polyether or polyester with polyisocyanate as main raw materials, supplemented by flame retardants, stabilizers and foaming agents. It has high closed-cell rate and low water absorption. Due to the presence of foaming agent gas with low thermal conductivity in its pores, it has certain heat resistance capability and is commonly used for cold insulation and thermal insulation in low-temperature ranges.
