What advantage does polyurethane foam machine have

Polyurethane foaming machine is applied in many fields: cold storage insulation, building external walls, roof, waterproof, sports venues, cars, boats, industrial anticorrosion, air conditioning insulation, solar water heater and other fields; All the key parts of the machine body are imported.

What are the advantages of polyurethane foaming machine?

1. Waterproof, anti-corrosion and anti-aging: as the closed-hole ratio of polyurethane foam is over 92%, the use of polyurethane foam as the insulation layer of the directly buried pipe can not only play a role in heat preservation and insulation, but also effectively prevent water, moisture and other corrosive liquids and gases from penetrating, and prevent the growth and development of microorganisms.

2. Low thermal conductivity: the thermal conductivity of polyurethane foam is the lowest among thermal insulation materials, so it can reduce the heat loss of materials to the minimum.
