Welcome to inquire! Contact: Zhu Yong. Rigid polyurethane foam board with low thermal conductivity preservation box, good thermal performance. When the density rigid polyurethane for 35 ~ 40kg / m3 when fresh foam box specifications, thermal conductivity is only 0.018g ~ 0.023w / (m.k), equivalent to about half of the fresh sales EPS foam boxes, and is all the insulation material the lowest thermal conductivity. Antifreeze is good: After 25 consecutive freeze-thaw test, the performance degradation rate of <5%, which makes the foam wall insulation board weather resistance, in a complex change in the weather itself remain stable physical and chemical properties.
