Outdoor Rainwater Barrier Properties Of Pre-insulated Sleeves

Under outdoor installation conditions, pre insulated sleeve exhibits a natural barrier against rain splashes. This barrier property stems from the combination of the pre insulated junction sleeve outer layer structure and materials, making it difficult for rainwater to directly penetrate the insulated joint sleeve surface and enter the internal insulation layer and piping system, thus maintaining the integrity of the component and the long-term stability of the outer protective layer.

The surface material, through design and manufacturing process control, can form a continuous, closed shell. This closed shell works in conjunction with the internal foam insulation layer, causing water droplets to slide off or disperse upon contact with the casing surface rather than seep in.
