The main characteristics of the thermal insulation materials used in the production line equipment of polyurethane exterior wall thermal insulation board:

  1. No burning, good high temperature resistance.
  2. The tough and slender fibers of sound-absorbing and noise-reducing cotton form an elastic porous connection structure, which can reduce the transmission of sound.
  3. Anti-mold and anti-bacterial, rock wool has good respiration. After water barrier treatment, it does not have a microbial growth environment to control the production of mold.
  4. Good thermal insulation performance, save energy, protect the environment, reduce energy consumption, reduce greenhouse effect and carbon dioxide emissions.
