Product description:

The interior of a polyurethane water heater casing typically contains an inner tank and a polyurethane insulation layer. The inner tank is the core component for storing hot water, generally made of materials such as stainless steel or enamel. Stainless steel inner tanks have good corrosion resistance and strength, while enamel inner tanks perform excellently in terms of corrosion and scale prevention. The polyurethane insulation layer tightly wraps the outside of the inner tank, formed by on-site foaming or pre-foaming and then installing. It is made by foaming a reaction of raw materials like isocyanate and polyol, and the resulting cellular structure effectively prevents heat transfer.

 

Performance and uses:

1 , Efficient insulation: Capable of keeping the hot water inside the water heater's inner tank at a high temperature for an extended period.

2 , Good water resistance: Due to the inherent good hydrophobic properties of polyurethane material, its closed-cell structure can effectively prevent moisture from entering the insulation layer. This not only ensures the durability of the insulation performance but also prevents damage to the insulation layer and corrosion of the inner tank caused by moisture ingress.

3 , Stable mechanical properties: The polyurethane insulation layer has certain elasticity and toughness, capable of withstanding external impacts and vibrations to a certain extent.
