Polyisocyanurate
Detailed Introduction
Specification Model:
保温保冷材料
Product Introduction
- Wear-resistant agent is a kind of solvent-based off-white flexible thick paste, which is mainly used between foam glass and base surface to prevent friction damage to the cold insulation layer of foam glass. It is usually preformed in the shop and coated on the surface of the inner layer of foam glass.
Adapt to the Scene
- Industrial chilled water pipeline cold insulation, cold storage insulation, air separation unit cold insulation, LNG supporting engineering, HVAC system cold insulation.
Product Features
- High efficiency and energy saving, adapting to the whole scene of medium and low temperature cold insulation, strong engineering versatility, reducing project energy consumption and construction costs.
