Product introduction:
PU exterior wall panel include 2 kinds : 1) with decorative gaps;2) without decorative gaps.The outer wall sandwich panel with seam is mainly suitable for horizontal installation of the outer wall, and the panel’ seam can be adjusted. The seamless building exterior wall panel is suitable for vertical or horizontal exterior walls. The scientific node design can effectively prevent the rainwater leakage of the vertical panel.

Features of PU exterior wall panel：
1. Wide temperature range
The use temperature of the core material is -196 ℃ ~ 130 ℃, and the instantaneous temperature reaches 200 ℃. When used in a low temperature or even lower environment, the shrinkage is small, and it is not brittle. It is an ideal thermal insulation material for cryogenic (cold storage) engineering.
2. Low thermal conductivity
The thermal conductivity of the composite PU panel is small, and the thermal insulation performance is good.
3. Non-toxic and tasteless
The core material of PU panel didn’t use Freon as a foaming agent. It is non-toxic and tasteless when burning, and the volatilized gas is harmless to the human environment. It meets the national environmental protection requirements and is a new type of green building material.
4. Waterproof and moistureproof
The core material of PU panel is an organic polymer foam material with a closed-cell structure, which has good water absorption and water vapor permeability resistance.
